Hope you enjoy this new episode of TikTok ridiculousness! I'm thinking the next episode might be TikTok "hacks"? Or are there tests I missed that you think I should talk about?
For the white board, if that's not a window behind the curtains you could mount it behind the curtains? Or mount it beside where the curtains are now and also mount an extra curtain panel to cover it sometimes? Or get a sturdy easel for it Also on the easel train, a chalkboard might look better blank so could hang out as background/bookstand when you weren't using it?
Something I struggle and concern over in my regimen is interactions. I've done a bit of searching on the web but it seems like there's a lot of varying/contradicting opinions, especially on TikTok and RUclips shorts. Hearing a chemist's opinion on common active interactions would be so so helpful!
Michelle thank you for this video!😊 Can you please give us a full Anatomy & Physiology lesson on the Integumentary System (Skin, Hair and nails) please!😅 You're the best teacher!
The way the last “doctor” just used the SAME STIRRING STICK in each little beaker. What is even happening here? At least pretend not to contaminate your experiments. 😂
I'm a medical doctor. We did a little bit of toxicology in 2nd year of med school. Can confirm, "The dose makes the poison" was literally the first title of the introduction to toxicology chapter.
Yeah, but if people use a plethora of products, day in, and day out, for decades, and Many of those products have toxic ingredients in them, then the totality of those toxic ingredients add up to a higher percentage of "Poison". The Food and Cosmetics Act hasn't been updated since the 1970's!!! So there are plenty of TOXIC chemicals out there that aren't even tested, nevertheless, there needs to be the consideration of the synergistic effects of Several of these toxic chemicals all interacting together. And that doesn't seem to be a concern of the chemists that have a financial stake in the outcome of the financial profits of the products that they formulate for Big Corporations.
My question is how do we know what the dose in a skincare/bodycare product is? Percentage wise I suppose. People say how bad petrolatum is for you in skincare formulations but obviously that, as both of you drs stated, is based on dose. So how are we as consumers to know what dose is considered unsafe and what the dose is in the product?
@@michelletidler6773typically, products provide an ideal “serving size” for each product or will ensure that one bottle or tube does not have enough to harm you
@@michelletidler6773 usually these products that have things that are harmful in larger doses will have instructions written on them and how often you can or should use them in a day which is measured against the safe percentages that are allowed in the area you're in (unless the amount is so small you could even use a whole bottle without nearing that dose). Its very rare that you'll find something that doesn't have this if it does have a larger amount of a substance that could cause harm if overused
The sunscreen guy drove me nuts, as soon as he started talking I thought "they already test the sunscreen!!! they already test it! that's where the spf number comes from!!!"
The thing I forgot to mention (that I mentioned in my comments on the post) is that I'm less annoyed at him, and more annoyed that OneSkin approved this as an ad - they should really know better.
@@carolinacarolina4950 I mean, Michelle already made a video about that back when it happened, and a handful of companies throughout the years circumventing regulations and getting caught doesn't mean the regulations are useless, definitely not to the level of this guy kinda implying in his post that you should assume a sunscreen is a fraud unless you test it yourself. In the US specifically they're regulated as drugs, so there's no need to be any more skeptical of a sunscreen than you are of a bottle of Tylenol or something
@@LabMuffinBeautyScience Definitely rather scummy of them to allow a non-specialist science communicator to represent their product in a way that is misleading but "accurate" for evaluating metrics irrelevant to actual efficacy. I think laypeople, even people who are rather science literate, can get fooled by a video like this. Despite the average person understanding on some level that specialists with degrees in their fields are more qualified than their favorite science communicator, they're more likely to trust that science communicator more than a rigorous number (SPF) because they've seen that person talk about science and teach them things and created a parasocial connection.
A generation ago, I worked at Sephora and was recommended to get one of those natural apps. I downloaded it and it shocked me. I looked up one of my personal care products, my eye drops. It said that it had a bad rating because it has propylene glycol in it. Propylene glycol irritates and causes your eyes to water; WHICH is what I want it to do! 😂 I was already very skeptical of the whole “clean” trend, but, this secured it for me! 😅😂 37:28
15:31 I totally get what the person is trying to say, but I love the implication that you want to put pure 100% vitamin c on your skin. The phrase "It contains pure X" is really funny to me in general, because it states that it is "pure" while also directly implying that it contains other ingredients. They didn't say "it IS pure vitamin C", you probably wouldn't want to put that on your face anyway. It's kind of like when water is labelled as "pure mineral water" when the whole point of getting mineral water is that it is not pure and contains minerals.
I think what I love about your content is that even though I learn a lot, you also convince me about how much I DONT KNOW which is kind of a relief to know that black and white is not a thing and pretty much anyone making blanket statements online you should be very skeptical of lol 🎉
Man, I really appreciate that lady using the Yuka app explaining that ingredients are safe when they’re natural minerals from the Earth. I can’t wait to bring my new brand of asbestos-based cosmetics to the market! It’s entirely 100% natural!
@@renaissancewoman3770Lead white makeup was popular in the past so it's also ✨traditional skincare✨, as we all know things being used in the past means it's good!
33:21 "this product doesn't break me out, should I stop using it?" no, you have already done n=1 science showing that it doesn't cause pimples on you specifically!
your "performance art" interpretation really inspires me to look at post like these in a different way. makes it a bit easier to cope with all the bs. :D
"The dose makes the poison" is so important, It's really good that more people know that phrase because of your videos. You need some water, too little water will leave you dehydrated, too much water will give you brain swelling, blood thinning and other life threatening symptoms. Water can be toxic just from the amount. It's the dose that makes the poison. This is also one of the reasons it is so important for your health care practitioner NEEDS to know your weight. It is LITERALLY a science to know what dose one may need and what may be too much or not enough of a possibly dangerous medicine for someone. Dose is important as heck.
It's also very easy to make water sound scary if you list all it's properties without context. Like did you know that water can spontanously turn into both an acid and a base? that water can cause proteins to misfold, or kill cells through osmotic pressure?
Just listening to your lip balm test discussion. it reminds me of the difference between accuracy and precision, and how precision is often mistaken for accuracy.
@@neuro-mm8in Precision (without accuracy): 2+2=5 Accuracy (without precision): 2+2>1 The first example is more precise bc the answer is a much narrower range. The second example is accurate because it's correct - even though the "range" of correct (ie, all numbers greater than 1) is pretty large, and hence not precise. Another way to think about it is the difference between a detailed false story (precision) and a vaguer recounting of... what the weather's like (accuracy). Ofc, it's obviously possible for an answer to be high in BOTH accuracy and precision, like 2+2=4. but they are still different concepts that often get muddled.
A better test for lip balm is going outside in southern NSW today (it’s freezing and very, VERY windy). Lanolips has done a terrific job (it’s the caramel one and so lovely to wear). Great video.
michelle! i would seriously love for u to do a video explaining active encapsulation. it's so hard to find layman's explanations for this topic 😢😢 like, we know the max molecular size for penetration is 500Da but do encapsulated actives still apply to this rule? & is there a difference in efficacy of liposomal encapsulates vs eg dextrin encapsulates. & how do encapsulated ingredients stay interact with surfactants & emulsifiers? love ur vids & love skincare science ❤
When people feel like they have no control over their lives they seek the little things they think they might be able to control as a coping mechanism, food especially often becomes a target. The growing distrust in authority (government, doctors etc.) is making it especially bad.
@@morgianasartre6709 it's called anti-intellectualism, something that the US is the best at, huge groups of people hating on experts thinking their dumb ideas are better than PhDs.
Although these tiktoks may seem harmless, to me they have deep undertones of science fearmongering and the anti-education movement. I thank you so so much for debunking these people and providing clarity. Don't even get me started on how much the word "theory" is misappropriated... like i have a "theory", no bro you have a thought. Also love listening to a fellow Aussie :)
That last one was wild, but I kind of appreciate that she didn't try to BS her way through it. "What does it all mean? I leave it to you, dear viewer, to draw your own conclusions." Me, I'm going with performance art because that would be hilarious.
Thank you Michelle, for your very informative videos. You've allowed me to use things without feeling like I need to over scrutinise everything. It's made me feel at ease and feel more relaxed instead of believing BS online.
Are we not going to talk about with the toast/sunscreen video that they put the toast in one direction and pulled it out another thinking we wouldn't see??
At this point I'm convinced that my chemistry degree of 4 years of studying made me more knowledgeable about skincare than most of these dermatologists who studied for 12 years will ever be. These tests done by dermatologists are honestly like middle school projects... What is this... Edit: The "dermatologist" at the end using the same pipette for all the different "tests" makes my skin itch
I think the disconnect is that skincare is a minuscule part of a dermatologist's standard training, but the really big social media-famous dermatologists make it seem like it's all they studied for 12 years. Most dermatologists get a couple of lectures (if that) on skincare, so when they try to expand that into 1000 TikTok posts it gets inaccurate quickly - I know quite a few dermatologists who are pretty annoyed at how the trend makes their profession (which is actually very complicated) seem like a joke. @doctordoublechin makes some hilarious reels about it on Instagram!
Yup. Biochem degree here. Definitely have a more advantage on skincare science. Though I still learn from cosmetic chemists and other ppl in the field like Lab Muffin because I don't work in the cosmetic industry 😁😁.
Can people claim they are dermatologists with no relevant qualifications...some professions have a protected standard in law and ppl who falsely claim the qualifications can be in trouble like dietitian you need the degree but anyone can say they are a nutritionist....
These videos always teach me so much and make me feel like a much better consumer of beauty information. I'm grateful you've become a relative expert in sunscreen science. It's really a gift to all of us since this is such an important but very neglected part of health education in the US.
I love how you make science so accessible without dumbing it down. Would be very interested to see a video on vitiligo and some of the weirder stuff around it like its relationship with vitamin C and D, and how it compares w eczemma as another autoimmune condition
Thank you! Please keep tagging me in them, it's really useful and even if I look like I'm not responding, I usually get around to talking about them (or other posts on the same topic!) ❤️
The reason I have used yuka in the past is not because I think companies are trying to harm me willingly through their products, but because they have made bad mistakes in the past and sometimes tried to cover their asses afterwards, delaying the recall of products. I had hoped that apps like yuka would help me avoid "suspect ingredients", but I see that it's very inconsistent. Would love to see you talk more in depth about these apps!
For me yuka has been great in my experience bec now i dont get rashes from my bath products anymore & my hair is the healthiest its been in years. And i havent had to spend a bunch of $$$ to get these results, using products from walmart. I feel like people don’t understand you need to use discernment when it comes to apps like these and ultimately trust your gut and do what’s better for your skin and hair. If you feel like the app is incorrectly labeling one of your favorite products that’s worked for you in the past as harmful when it’s not then maybe you should trust yourself instead of an app 🤔
Video idea for when you’re too busy for all the research (even you need breaks 😊) - I would love to see your lipstick/lip product collection! I notice you don’t always wear the same makeup but you’ve found a really gorgeous shade range for yourself, and I’d love to see what you use and hear about your preferences - if im right, you focus color & shine on your lips usually. I’m currently obsessed with mentholatum brand (no menthol in them tho) tinted spf balms & layering tints/stains with spf. I’m hoping you’ve got some spf lippies I am not familiar with, tbh. After spending $25 on 6 k-beauty lip products that all look & feel amazing, I’m done with western lippies. I spent 30 years looking for lip products like these, I’m pretty sure I could have gotten them ten years ago at least, and how did I not know how affordable some of these very posh products are?
To be honest my lip product collection is pretty weak - in my videos I'm almost always wearing Revlon Toast of New York with a lip gloss on top (currently using Australis Lip Glaze). Sometimes I blot off more colour to add variety 😅 Which K-beauty products do you use? I'd love some recommendations!
no shame to anyone -- no one pronounces it how I learned back in college when dinosaurs still roamed the planet, but it's pronounced "MY-yard" (like my yard, not your yard), not mall-ee-yard. love your work SO much.
Thank you for educating us on the misinfomation being spread on tictok, even by doctors. Have you ever done a video on facial steaming? Some beauty experts agree with doing it, and some speak against doing it. I was wondering about it.
I have never watched a video on cosmetics before. I kind of hate even looking at cosmetics because the advertizing feels really deceptive. I was instantly entraced by this video. This was great and I feel like I learned a lot!! So happy to stumble onto a great science communicator in this field with a good sense of humor! I have a PhD in geochem and work on ISO standards, I really appreciate the attention paid to the work people put into the industry standard analytical methods!!
It’s perfect timing for me to be learning as much as my brain can from your videos 😅 because I’ve just been watching people, whom I consider quite stupid, convincing people that the tests they’ve done are showing that your products are harming you. The fact that if someone posts a video, everyone seems to suddenly believe it, without even looking into the person who’s telling them this, or what education they’ve had. It’s ridiculous just how blindly people believe anyone and also dangerous. This is why I love your channel and as one of my daughters has a science PhD, except based on a different area to you, I know just how hard you have to work, study with blood, sweat and tears to get there. ❤
Yay, Michelle in the house! Breakfast and anti-BS - awesome! Random comment re: differing physiology - you can give a dog paracetamol (though there are better options) but NOT cats!
There is also an anti-convulsant drug (gabapentin) for humans that works (in an animal-appropriate dose) as an anti-anxiety med for cats 🤷♀ humans and different animals have different amounts of chromosomes, and many animals grow full body fur, which should tell us something about their different physiology already.
@@lillylilium497 It's actually used in dogs for pain relief too (as well as anxiety), as it helps block stimulation of nerve cells. The presence or absence of fur has less to do with physiology though :)
@@lillylilium497 gabapentin has a number of effects on humans that it's prescribed for, including anticonvulsant effects, treatment of pain (specifically nerve pain), and has been used for anti-anxiety/ sedation. so not the best example of meds working differently in animals - but it's kind of a weird medication anyway because its effects on just humans can be so vastly different from person to person
I love your videos xxx I would love a video about UV nail lamps and their safety/dangers etc. as someone who gets their nails done fortnightly…. I’d like to know my risk of skin cancer from prolonged use with these UV lights, why they sometimes cause hot spots on the nail, and why generally my nail health has declined from getting them done, whether that be due to the files, UV, etc. AND if it is worthwhile for me to wear gloves or sunscreen to the salon…. On a similar vein, wtf is red light therapy!
I often wonder at these "pore-clogging" vs not ingredients. I have the impression that for my skin, it's not "pore-clogging" ingredients but rather ingredients that irritate my sensitive skin that cause breakouts. A lot of products (including "natural" ones) irritate my skin and cause spots, but I can put Nivea creme (the super thick gloop that comes in a blue tin) on my face with no issues.
there are actually no known comedogenic ingredients (not anything that is cosmetics anyway). It's layering and overuse of products that tends to cause clogging.
@@SueRosalie Sure. What I'm saying is that I wonder if, like me, the "acne" reaction some people have to some products is a reaction to irritating ingredients rather than blocked pores. I wear no make-up, only moisturizer and sunblock in summer, so it's definitely not over layering in my case; there are some products I just get an irritated skin reaction to and this also results in red spots that look a lot like acne. I would guess there are others like me who thought they had very greasy clogging-prone skin but in fact just have sensitive skin that gets irritated easily. For example, I know now not to try "natural" creams that have a huge list of different plant extracts and oils in them, since the likelihood that one of them will irritate my skin is high.
Can you a video overview on hair? I’m curious to know where you stand on things. I’ve been listening to a lot of The Beauty Brains podcast lately and I’m surprised how much skepticism there is around products, especially bond builders, protein, citric acid and chelating shampoos. There have been a ton of new bond builders, such as K18, Epres, Living Proof, CurlSmith, Paul Mitchell, Not Your Mothers Tough Love, Garnier Filler and even Dove has a Bond Strength line now. Would love to hear your thoughts on the efficacy of these products. If you do, can you also speak on a couple things 1 - Do bond shampoos offer any real “bond” benefit to the hair when they are usually only used on the scalp for a minute before being rinsed off? Are we to understand that the suds simply running down the ends for a few seconds while being rinsed off is enough to repair bonds on the lengths because of some super advanced technology? 2 - A handful of brands also offer oils/serums that claim to have their bonding technology in it. K18 has at least started their oil only has bonding benefits when it’s applied to damp hair. Others such as, Olaplex, Paul Mitchell EverStrong, Quidad don’t mention any limit of that sort on their oils. Is it physically possible for these products to still repair bonds on dry hair? Which I would assume that means that all conditioning agents from conditioner, leave ins, styling products are semi permeable in order for this to happen? 3 - Concerning citric acid preshampoos, or even the CurlSmith Bond Salve/ Olaplex #3 and Not Your Mothers Tough Love pre shampoo, do we get benefits from these products when applied as directed on dirty hair? I’ve seen a few hair influencers, especially Abbey Yung, claim that these types of products work better when applied on freshly shampooed hair. My question is, are the benefits of using these products as directed inferior to those benefits that you would get on washing after clean hair? I only want to do what will give my hair the most effective result. So why are brands marketing these products to be directed in a way that is not as helpful? 3a - Does the hair get better results leaving in these treatments longer than directed or are the results the same no matter the time spent in the hair? If the science says the results you get from 1 minute are the same as leaving in for 10 minutes, I would love to know that so I can stop wasting my time in the name of healthier hair. In a similar vein, how can a consumer decipher if the results of using as directed are the most efficacious when most hair treatments/masks don’t state the time a products taps out? Should we just trust the label directions or the influencers who claim you can get more benefit with longer wait times? 4 - Is it correct to assume that if bond building treatments work the way they say they do, those benefits would not be noticeable to the consumer? The Beauty Brains podcast has mentioned a similar sentiment that even if the hair bonds are getting stronger, they wouldn’t be noticeable to the user, which I am, personally fine with. I use bond repair products with the hope that my hair is indeed getting stronger so it can withstand more wear and tear as it grows out. I seek to my rinse out conditioners and leave in products to get my hair well conditioned. But the question stands, do these benefits of bond repair work even if a person can tell no difference in their hair? Abbey Yungs microscopic strand tests kind of reminds me of this issue, not being able to quantify the results of products like this. So do the people who not notice a difference not see a difference because A- they are not physically able to feel a difference even though the said ingredient is doing what it needs to do or B- because the products can’t do what they claim to do and you wouldn’t be able to tell /prove the difference anyway? 4 - Lastly, on the Beauty Brains podcast episode 328 Perry states that chelating shampoos are a marketing gimmicking. He said there isn’t enough chelating agents in shampoos to make much impact in mineral removal and that a regular shampoo would remove minerals. What is your take on this? This isn’t a problem I have personally but it surprised me when he said this because of all the success I’ve read with people who do struggle with hard water. I would really love if you could take the time to respond to these questions. It is a struggle to try to find out this kind of information when you don’t have the knowledge or background that you do. Especially when a lot of other influencers and scientists themselves are claiming different things. I just want what is most efficacious for my hair and I think the majority of people can relate to that as well. We just want to save our time and money. If all of this is a bunch of bull crap please set us free from these myths so we can move on.
That's a lot of questions, it would be many many videos! I do plan to do more hair science videos soon that will cover some of the many myths out there. But in short, I disagree with The Beauty Brains on a lot of things - I think Perry tends to be too cynical (understandable), I remember him saying that he doesn't think any cosmetic skincare products work because cosmetics legally aren't allowed to change the structure or function of skin, for instance. I also have a write-up on my blog responding to their tranexamic acid episode. On hair science, TRI Princeton is a fantastic source - their research has found that bond building and chelating products do work, but it seems like there isn't a good way to work out which products work best without testing the individual product (not that dissimilar to skincare, really!). Unfortunately Abbey Yung's microscope test was simply the wrong test for bond building products - it only shows the morphology of the cuticle surface, which bond building products have minimal impact on (bonds are too small to be seen), so it was actually more of a test for conditioning. TRI Princeton's tests for those are generally mechanical e.g. seeing how much hair stretches when wet vs dry, which is also what consumers should be able to observe. Bond building products need to be used on the hair - I focus bond building shampoos less on the scalp and more on the actual hair.
@@LabMuffinBeautyScienceThank you so much for replying!!! It’s a dream come true, truly. I’m already really looking forward for your upcoming videos about these topics. We would all love to hear what you and the science has to say about all this 💕❤️
For myself who does find scientific explanations a lot of the time intimidated, I appreciate how you explain things so much and making it accessible (and fun!!)
I specifically clicked for the yuka explanation. I was using it for a while and I swear every food I ate was a hazard in some way. Things like Gatorade, certain canned food, even a nature granola bar. I eat in a relatively moderate way, and this app was making me so paranoid and not wanting to eat anything. I had to stop using it. I was like I already know you just have to balance how you eat to be most healthy about it. I didn't even want to venture over into the beauty and home side of the app
one thing i heavily suggest for people with acne prone skin (such as myself) is an aloe vera based primer (i use straight up aloe vera gel, it gets sticky which helps the makeup stick, while also protecting my skin) along with not wearing the makeup too heavily and not wearing it for too long, aswell as thoroughly washing your face and moisturizing afterwards, and giving your skin a few days between the times you wear makeup to rest and self-clean, while of course consistently washing it, by doing this i've found my acne to be decreasing and my skin to even look better the day after wearing makeup! and if you still want to wear makeup during your resting day, wearing some while avoiding skin products like foundation is completely safe, as long as you prep well and keep your skin as clean as possible! ❤
thank you i do enjoy the tiktokery it is a pretty fun way to get educated about chemistry, the scientific method, product regulation, and all those fun things :)
Your channel is basically the only beauty channel I watch. I don't care much about skin care (except for sunscreen, cancer and stuff), but I find the insights into how skin care research works fascinating. Edit: Even with only a Highschool chemistry education I called the lack of water in the vaseline pH test. Foolishness is really unbounded. 😆
We discussed this briefly on twitter once, yes, as medical students we do extensive pharmacology, and also toxicology, forensic medicine and epidemiology. There is no excuse for MDs to not understand "the dose makes the poison" or how to interpret studies. It's so disappointing.
I found myself… like, coming back to this video and just clicking it…. Or leaving it on with low volume….. Thanks so much for being one of the few voices of reason!!!!! I know it must get exhausting and frustrating … but the hope you give me through knowing I am not alone is really priceless. Thanks for all you do to make the world beautiful 🎀🤭🙏💕
I love your videos, my only disagreement is with the 'not killing your customers' being good business practice. It is important to remember that a company is not run by a single person with a vested interest in the long term outcome of that company. As long as you don't kill the customer fast enough to raise any flags in the coming 30 or so years, whatever people are currently 'running' the company can safely retire before the company is ever put under scrutiny and slapped with fees that barely make a dent.
In that case, the problem would be leaks - the larger the company, the harder it is to keep a secret www.ox.ac.uk/news/2016-01-26-too-many-minions-spoil-plot
Thank you for helping me FINALLY begin to understand ph. I really like your debunking videos, they are soooo helpful in todays digital world where anyone can spread fancy but false info.
Can i just say thank you for choosing to sit down and break down this stuff for us! Things that we would need to go to college for or study online for hours and hours just to try and grasp some of these concepts and ideas. Thank you so much!! ❤
Your videos are always great to watch. I am not very interested personally in beauty products but as a scientist and industrial manufacturing chemist I am greatly appreciative of the rigorous analysis you bring to discussions of these products. I am definitely going to have a read of the new developed methods for testing SPF (cuz I be that kind of nerd 🤣) but would love to see a video of you breaking down the general regulatory requirements and pros/cons within the industry when it comes to public safety/efficacy.
Love the video. I can't however, look at it due to the camera focus jumping on and off the background, it's really visible on the tiny lights in the back. Listened to it as a podcast and it's really informational
i can't comment again about how helpful and awesome michelle's videos are, it's too unoriginal. so i'll comment about the background. watch the twinkle lights on the left, they go in and out of focus, it's trippy!
For your whiteboard: maybe an easel could work? (Unless you want the surface to stay slanted) That way it would be at a more comfortable height, and be much more stable than a desk chair. However, it might take up too much space... You could also potentially mount the whiteboard on a wall if you want it to stay in one spot?
I’m totally fine with you just holding the whiteboard up, but if you want a stand, the make good-quality-but-inexpensive collapsible stands that can hold whiteboards of that size. I have one in a desk drawer, in case I fill my wall-mounted whiteboard and briefly need extra space. They’re very handy because they’re really compact.
Michelle, it’s you against TikTok. I admire you so much! Thank you for all the work that you do. You inspire me to try to get to the cosmetic formulation industry to obliterate the “organic/clean/natural is better” movement! Get them!! Slaaaaay queen! lol
The only use I found for Yuka is having the inci list writen clearly, cuz damn you need to have perfect vision to read the labels on those cosmetic products.
Thanks for this fun video! People in the skincare community often refer to ascorbic acid as “pure” ascorbic acid to differentiate from its derivatives. Yet, we don’t say “pure” retinoic acid to differentiate from its alcohol or aldehyde precursors.
My favorite whiteboard is standing behind something clear like glass or acrylic and writing on it however it'll look backwards when playing the video backwards. In post processing you can fix the error by mirroring the image.
The dermatologist in the last tiktoks works at a Florida medspa. Medspas always make me worry that they convince people to get treatments that don't actually work or are not worth the cost. I would love a video talking about the actual science behind skincare treatments at medspas.
Love your informative videos, Michelle! Perhaps using an iPad/tablet to drawing or screen-record can be helpful for making those visuals! Or you can project/print a photo and draw/label over it. Real-time drawings and labeling are especially helpful during my chemistry lectures, and perhaps would be helpful here as well!
Hope you enjoy this new episode of TikTok ridiculousness!
I'm thinking the next episode might be TikTok "hacks"? Or are there tests I missed that you think I should talk about?

Yeah, but if people use a plethora of products, day in, and day out, for decades, and Many of those products have toxic ingredients in them, then the totality of those toxic ingredients add up to a higher percentage of "Poison".
The Food and Cosmetics Act hasn't been updated since the 1970's!!! So there are plenty of TOXIC chemicals out there that aren't even tested, nevertheless, there needs to be the consideration of the synergistic effects of Several of these toxic chemicals all interacting together.
And that doesn't seem to be a concern of the chemists that have a financial stake in the outcome of the financial profits of the products that they formulate for Big Corporations.
So, true
My question is how do we know what the dose in a skincare/bodycare product is? Percentage wise I suppose. People say how bad petrolatum is for you in skincare formulations but obviously that, as both of you drs stated, is based on dose. So how are we as consumers to know what dose is considered unsafe and what the dose is in the product?
@@michelletidler6773typically, products provide an ideal “serving size” for each product or will ensure that one bottle or tube does not have enough to harm you
@@michelletidler6773 usually these products that have things that are harmful in larger doses will have instructions written on them and how often you can or should use them in a day which is measured against the safe percentages that are allowed in the area you're in (unless the amount is so small you could even use a whole bottle without nearing that dose). Its very rare that you'll find something that doesn't have this if it does have a larger amount of a substance that could cause harm if overused
woah first explanation is already godlike, you explained thermodynamics in the most simple way I've seen
Thank you so much, that's a massive compliment! I've been workshopping that explanation for like 5 years 😅

The sunscreen guy drove me nuts, as soon as he started talking I thought "they already test the sunscreen!!! they already test it! that's where the spf number comes from!!!"
The thing I forgot to mention (that I mentioned in my comments on the post) is that I'm less annoyed at him, and more annoyed that OneSkin approved this as an ad - they should really know better.
Happened actually, with Purito i believe, it said a spf but didn't have that spf 🤔
@@carolinacarolina4950 I mean, Michelle already made a video about that back when it happened, and a handful of companies throughout the years circumventing regulations and getting caught doesn't mean the regulations are useless, definitely not to the level of this guy kinda implying in his post that you should assume a sunscreen is a fraud unless you test it yourself. In the US specifically they're regulated as drugs, so there's no need to be any more skeptical of a sunscreen than you are of a bottle of Tylenol or something
@@LabMuffinBeautyScience Definitely rather scummy of them to allow a non-specialist science communicator to represent their product in a way that is misleading but "accurate" for evaluating metrics irrelevant to actual efficacy. I think laypeople, even people who are rather science literate, can get fooled by a video like this. Despite the average person understanding on some level that specialists with degrees in their fields are more qualified than their favorite science communicator, they're more likely to trust that science communicator more than a rigorous number (SPF) because they've seen that person talk about science and teach them things and created a parasocial connection.

A generation ago, I worked at Sephora and was recommended to get one of those natural apps. I downloaded it and it shocked me. I looked up one of my personal care products, my eye drops. It said that it had a bad rating because it has propylene glycol in it. Propylene glycol irritates and causes your eyes to water; WHICH is what I want it to do! 😂 I was already very skeptical of the whole “clean” trend, but, this secured it for me! 😅😂 37:28
My local library just got a few copies of The Science of Beauty! 🥳 I’m reading it right now and loving it. Thank you, Michelle. 💕
That's great to hear! 😊
15:31 I totally get what the person is trying to say, but I love the implication that you want to put pure 100% vitamin c on your skin. The phrase "It contains pure X" is really funny to me in general, because it states that it is "pure" while also directly implying that it contains other ingredients. They didn't say "it IS pure vitamin C", you probably wouldn't want to put that on your face anyway. It's kind of like when water is labelled as "pure mineral water" when the whole point of getting mineral water is that it is not pure and contains minerals.
Cornering the market by selling fist-sized ✨crystals✨ of ✨pure and natural✨ vitamin C for you to rub on your face
Hell yes!!!!!!
@@MarcusMedomRyding Gonna steal some samples from my uni's crystallography setup and start selling them as beauty products.

Being skeptical comes from being science-minded
wakeup babe, new Michelle video just dropped
Hope it was worth waking up for! 😊
@@LabMuffinBeautyScienceamazing video, you always describe it so nicely especially for people who may not know the correct things yet

33:21 "this product doesn't break me out, should I stop using it?" no, you have already done n=1 science showing that it doesn't cause pimples on you specifically!
your "performance art" interpretation really inspires me to look at post like these in a different way. makes it a bit easier to cope with all the bs. :D
We all need more coping mechanisms for the relentless flood of BS haha
"The dose makes the poison" is so important, It's really good that more people know that phrase because of your videos. You need some water, too little water will leave you dehydrated, too much water will give you brain swelling, blood thinning and other life threatening symptoms. Water can be toxic just from the amount. It's the dose that makes the poison. This is also one of the reasons it is so important for your health care practitioner NEEDS to know your weight. It is LITERALLY a science to know what dose one may need and what may be too much or not enough of a possibly dangerous medicine for someone. Dose is important as heck.
It's also very easy to make water sound scary if you list all it's properties without context. Like did you know that water can spontanously turn into both an acid and a base? that water can cause proteins to misfold, or kill cells through osmotic pressure?
Just listening to your lip balm test discussion. it reminds me of the difference between accuracy and precision, and how precision is often mistaken for accuracy.
I was hoping you were going to explain the difference
@@neuro-mm8in Precision (without accuracy): 2+2=5
Accuracy (without precision): 2+2>1
The first example is more precise bc the answer is a much narrower range. The second example is accurate because it's correct - even though the "range" of correct (ie, all numbers greater than 1) is pretty large, and hence not precise.
Another way to think about it is the difference between a detailed false story (precision) and a vaguer recounting of... what the weather's like (accuracy).
Ofc, it's obviously possible for an answer to be high in BOTH accuracy and precision, like 2+2=4. but they are still different concepts that often get muddled.
A better test for lip balm is going outside in southern NSW today (it’s freezing and very, VERY windy). Lanolips has done a terrific job (it’s the caramel one and so lovely to wear). Great video.

😖. “Ugh. ‘Clean’…gross!” Made me laugh out loud.
I am perplexed by how many people are obsessed with toxicity in skin care, food, etc…
Ocd, magical thinking, etc
a lot of people are very ill and they don't really know why, it's honestly very sad
When people feel like they have no control over their lives they seek the little things they think they might be able to control as a coping mechanism, food especially often becomes a target. The growing distrust in authority (government, doctors etc.) is making it especially bad.
The granola mom to conspiracy theory right winger isn't such a big pipeline.
@@morgianasartre6709 it's called anti-intellectualism, something that the US is the best at, huge groups of people hating on experts thinking their dumb ideas are better than PhDs.
Although these tiktoks may seem harmless, to me they have deep undertones of science fearmongering and the anti-education movement. I thank you so so much for debunking these people and providing clarity. Don't even get me started on how much the word "theory" is misappropriated... like i have a "theory", no bro you have a thought. Also love listening to a fellow Aussie :)
That last one was wild, but I kind of appreciate that she didn't try to BS her way through it. "What does it all mean? I leave it to you, dear viewer, to draw your own conclusions." Me, I'm going with performance art because that would be hilarious.
Just started the video but I wanted to comment early for the algo because people really need to see this.
Thank you! Appreciate it ❤️
Thank you Michelle, for your very informative videos. You've allowed me to use things without feeling like I need to over scrutinise everything. It's made me feel at ease and feel more relaxed instead of believing BS online.
That's lovely to hear! 😊
Are we not going to talk about with the toast/sunscreen video that they put the toast in one direction and pulled it out another thinking we wouldn't see??
At this point I'm convinced that my chemistry degree of 4 years of studying made me more knowledgeable about skincare than most of these dermatologists who studied for 12 years will ever be. These tests done by dermatologists are honestly like middle school projects... What is this...
Edit: The "dermatologist" at the end using the same pipette for all the different "tests" makes my skin itch
I think the disconnect is that skincare is a minuscule part of a dermatologist's standard training, but the really big social media-famous dermatologists make it seem like it's all they studied for 12 years. Most dermatologists get a couple of lectures (if that) on skincare, so when they try to expand that into 1000 TikTok posts it gets inaccurate quickly - I know quite a few dermatologists who are pretty annoyed at how the trend makes their profession (which is actually very complicated) seem like a joke. @doctordoublechin makes some hilarious reels about it on Instagram!
Yup. Biochem degree here. Definitely have a more advantage on skincare science. Though I still learn from cosmetic chemists and other ppl in the field like Lab Muffin because I don't work in the cosmetic industry 😁😁.
@LabMuffinBeautyScience omg love that guy. He's hilarious!!!
Can people claim they are dermatologists with no relevant qualifications...some professions have a protected standard in law and ppl who falsely claim the qualifications can be in trouble like dietitian you need the degree but anyone can say they are a nutritionist....
@@anahiramirez5054 Really? My bachelor's is in Biochem but I had exactly 0 on skincare.

These videos always teach me so much and make me feel like a much better consumer of beauty information. I'm grateful you've become a relative expert in sunscreen science. It's really a gift to all of us since this is such an important but very neglected part of health education in the US.

"...I know too much now" 🤣 truer words have never been spoken. Ignorance is bliss. I love these videos 😍
Thank you! 😊
for some reason the tiny stump test is really sending me lol
The reason I have used yuka in the past is not because I think companies are trying to harm me willingly through their products, but because they have made bad mistakes in the past and sometimes tried to cover their asses afterwards, delaying the recall of products. I had hoped that apps like yuka would help me avoid "suspect ingredients", but I see that it's very inconsistent. Would love to see you talk more in depth about these apps!
For me yuka has been great in my experience bec now i dont get rashes from my bath products anymore & my hair is the healthiest its been in years. And i havent had to spend a bunch of $$$ to get these results, using products from walmart. I feel like people don’t understand you need to use discernment when it comes to apps like these and ultimately trust your gut and do what’s better for your skin and hair. If you feel like the app is incorrectly labeling one of your favorite products that’s worked for you in the past as harmful when it’s not then maybe you should trust yourself instead of an app 🤔
You can also find the same information on the website of the regulatory body for wherever you live.
Video idea for when you’re too busy for all the research (even you need breaks 😊) - I would love to see your lipstick/lip product collection! I notice you don’t always wear the same makeup but you’ve found a really gorgeous shade range for yourself, and I’d love to see what you use and hear about your preferences - if im right, you focus color & shine on your lips usually. I’m currently obsessed with mentholatum brand (no menthol in them tho) tinted spf balms & layering tints/stains with spf. I’m hoping you’ve got some spf lippies I am not familiar with, tbh. After spending $25 on 6 k-beauty lip products that all look & feel amazing, I’m done with western lippies. I spent 30 years looking for lip products like these, I’m pretty sure I could have gotten them ten years ago at least, and how did I not know how affordable some of these very posh products are?
To be honest my lip product collection is pretty weak - in my videos I'm almost always wearing Revlon Toast of New York with a lip gloss on top (currently using Australis Lip Glaze). Sometimes I blot off more colour to add variety 😅 Which K-beauty products do you use? I'd love some recommendations!
no shame to anyone -- no one pronounces it how I learned back in college when dinosaurs still roamed the planet, but it's pronounced "MY-yard" (like my yard, not your yard), not mall-ee-yard. love your work SO much.
Thank you for educating us on the misinfomation being spread on tictok, even by doctors. Have you ever done a video on facial steaming? Some beauty experts agree with doing it, and some speak against doing it. I was wondering about it.
I'm so glad you covered the toaster one, I saw a different version and everyone in the comments were calling out the BS lol
I have never watched a video on cosmetics before. I kind of hate even looking at cosmetics because the advertizing feels really deceptive. I was instantly entraced by this video. This was great and I feel like I learned a lot!! So happy to stumble onto a great science communicator in this field with a good sense of humor!
I have a PhD in geochem and work on ISO standards, I really appreciate the attention paid to the work people put into the industry standard analytical methods!!
It’s perfect timing for me to be learning as much as my brain can from your videos 😅 because I’ve just been watching people, whom I consider quite stupid, convincing people that the tests they’ve done are showing that your products are harming you. The fact that if someone posts a video, everyone seems to suddenly believe it, without even looking into the person who’s telling them this, or what education they’ve had. It’s ridiculous just how blindly people believe anyone and also dangerous. This is why I love your channel and as one of my daughters has a science PhD, except based on a different area to you, I know just how hard you have to work, study with blood, sweat and tears to get there. ❤
Yay, Michelle in the house! Breakfast and anti-BS - awesome! Random comment re: differing physiology - you can give a dog paracetamol (though there are better options) but NOT cats!
My sister's cats are going through random health issues, and it's so interesting to see what meds they get prescribed 😊
There is also an anti-convulsant drug (gabapentin) for humans that works (in an animal-appropriate dose) as an anti-anxiety med for cats 🤷♀ humans and different animals have different amounts of chromosomes, and many animals grow full body fur, which should tell us something about their different physiology already.
@@lillylilium497 It's actually used in dogs for pain relief too (as well as anxiety), as it helps block stimulation of nerve cells. The presence or absence of fur has less to do with physiology though :)
@@LabMuffinBeautyScience Selmintra/Telmisartan? Istin? Felimazole? (Just running through the common stuff in my head 😁)
@@lillylilium497 gabapentin has a number of effects on humans that it's prescribed for, including anticonvulsant effects, treatment of pain (specifically nerve pain), and has been used for anti-anxiety/ sedation.
so not the best example of meds working differently in animals - but it's kind of a weird medication anyway because its effects on just humans can be so vastly different from person to person
I love your videos xxx I would love a video about UV nail lamps and their safety/dangers etc. as someone who gets their nails done fortnightly…. I’d like to know my risk of skin cancer from prolonged use with these UV lights, why they sometimes cause hot spots on the nail, and why generally my nail health has declined from getting them done, whether that be due to the files, UV, etc. AND if it is worthwhile for me to wear gloves or sunscreen to the salon…. On a similar vein, wtf is red light therapy!
I often wonder at these "pore-clogging" vs not ingredients. I have the impression that for my skin, it's not "pore-clogging" ingredients but rather ingredients that irritate my sensitive skin that cause breakouts. A lot of products (including "natural" ones) irritate my skin and cause spots, but I can put Nivea creme (the super thick gloop that comes in a blue tin) on my face with no issues.
there are actually no known comedogenic ingredients (not anything that is cosmetics anyway). It's layering and overuse of products that tends to cause clogging.
@@SueRosalie Sure. What I'm saying is that I wonder if, like me, the "acne" reaction some people have to some products is a reaction to irritating ingredients rather than blocked pores. I wear no make-up, only moisturizer and sunblock in summer, so it's definitely not over layering in my case; there are some products I just get an irritated skin reaction to and this also results in red spots that look a lot like acne. I would guess there are others like me who thought they had very greasy clogging-prone skin but in fact just have sensitive skin that gets irritated easily. For example, I know now not to try "natural" creams that have a huge list of different plant extracts and oils in them, since the likelihood that one of them will irritate my skin is high.
I wish you were my chemistry teacher. Your explanations are great!
You're so insightful! I would have 100% fallen for some of these demos without your education.
Can you a video overview on hair? I’m curious to know where you stand on things. I’ve been listening to a lot of The Beauty Brains podcast lately and I’m surprised how much skepticism there is around products, especially bond builders, protein, citric acid and chelating shampoos. There have been a ton of new bond builders, such as K18, Epres, Living Proof, CurlSmith, Paul Mitchell, Not Your Mothers Tough Love, Garnier Filler and even Dove has a Bond Strength line now. Would love to hear your thoughts on the efficacy of these products.
If you do, can you also speak on a couple things
1 - Do bond shampoos offer any real “bond” benefit to the hair when they are usually only used on the scalp for a minute before being rinsed off? Are we to understand that the suds simply running down the ends for a few seconds while being rinsed off is enough to repair bonds on the lengths because of some super advanced technology?
2 - A handful of brands also offer oils/serums that claim to have their bonding technology in it. K18 has at least started their oil only has bonding benefits when it’s applied to damp hair. Others such as, Olaplex, Paul Mitchell EverStrong, Quidad don’t mention any limit of that sort on their oils. Is it physically possible for these products to still repair bonds on dry hair? Which I would assume that means that all conditioning agents from conditioner, leave ins, styling products are semi permeable in order for this to happen?
3 - Concerning citric acid preshampoos, or even the CurlSmith Bond Salve/ Olaplex #3 and Not Your Mothers Tough Love pre shampoo, do we get benefits from these products when applied as directed on dirty hair? I’ve seen a few hair influencers, especially Abbey Yung, claim that these types of products work better when applied on freshly shampooed hair. My question is, are the benefits of using these products as directed inferior to those benefits that you would get on washing after clean hair? I only want to do what will give my hair the most effective result. So why are brands marketing these products to be directed in a way that is not as helpful?
3a - Does the hair get better results leaving in these treatments longer than directed or are the results the same no matter the time spent in the hair? If the science says the results you get from 1 minute are the same as leaving in for 10 minutes, I would love to know that so I can stop wasting my time in the name of healthier hair. In a similar vein, how can a consumer decipher if the results of using as directed are the most efficacious when most hair treatments/masks don’t state the time a products taps out? Should we just trust the label directions or the influencers who claim you can get more benefit with longer wait times?
4 - Is it correct to assume that if bond building treatments work the way they say they do, those benefits would not be noticeable to the consumer? The Beauty Brains podcast has mentioned a similar sentiment that even if the hair bonds are getting stronger, they wouldn’t be noticeable to the user, which I am, personally fine with. I use bond repair products with the hope that my hair is indeed getting stronger so it can withstand more wear and tear as it grows out. I seek to my rinse out conditioners and leave in products to get my hair well conditioned. But the question stands, do these benefits of bond repair work even if a person can tell no difference in their hair? Abbey Yungs microscopic strand tests kind of reminds me of this issue, not being able to quantify the results of products like this. So do the people who not notice a difference not see a difference because A- they are not physically able to feel a difference even though the said ingredient is doing what it needs to do or B- because the products can’t do what they claim to do and you wouldn’t be able to tell /prove the difference anyway?
4 - Lastly, on the Beauty Brains podcast episode 328 Perry states that chelating shampoos are a marketing gimmicking. He said there isn’t enough chelating agents in shampoos to make much impact in mineral removal and that a regular shampoo would remove minerals. What is your take on this? This isn’t a problem I have personally but it surprised me when he said this because of all the success I’ve read with people who do struggle with hard water.
I would really love if you could take the time to respond to these questions. It is a struggle to try to find out this kind of information when you don’t have the knowledge or background that you do. Especially when a lot of other influencers and scientists themselves are claiming different things. I just want what is most efficacious for my hair and I think the majority of people can relate to that as well. We just want to save our time and money. If all of this is a bunch of bull crap please set us free from these myths so we can move on.
That's a lot of questions, it would be many many videos! I do plan to do more hair science videos soon that will cover some of the many myths out there.
But in short, I disagree with The Beauty Brains on a lot of things - I think Perry tends to be too cynical (understandable), I remember him saying that he doesn't think any cosmetic skincare products work because cosmetics legally aren't allowed to change the structure or function of skin, for instance. I also have a write-up on my blog responding to their tranexamic acid episode.
On hair science, TRI Princeton is a fantastic source - their research has found that bond building and chelating products do work, but it seems like there isn't a good way to work out which products work best without testing the individual product (not that dissimilar to skincare, really!). Unfortunately Abbey Yung's microscope test was simply the wrong test for bond building products - it only shows the morphology of the cuticle surface, which bond building products have minimal impact on (bonds are too small to be seen), so it was actually more of a test for conditioning. TRI Princeton's tests for those are generally mechanical e.g. seeing how much hair stretches when wet vs dry, which is also what consumers should be able to observe.
Bond building products need to be used on the hair - I focus bond building shampoos less on the scalp and more on the actual hair.
@@LabMuffinBeautyScienceThank you so much for replying!!! It’s a dream come true, truly. I’m already really looking forward for your upcoming videos about these topics. We would all love to hear what you and the science has to say about all this 💕❤️
For myself who does find scientific explanations a lot of the time intimidated, I appreciate how you explain things so much and making it accessible (and fun!!)
I specifically clicked for the yuka explanation. I was using it for a while and I swear every food I ate was a hazard in some way. Things like Gatorade, certain canned food, even a nature granola bar. I eat in a relatively moderate way, and this app was making me so paranoid and not wanting to eat anything. I had to stop using it. I was like I already know you just have to balance how you eat to be most healthy about it. I didn't even want to venture over into the beauty and home side of the app
I'm obsessed with all of the sunscreen science you share with us. thank you for being SO cool!!!
I'm so glad you're doing this. Thank you for being the voice of reason and science in this space.
one thing i heavily suggest for people with acne prone skin (such as myself) is an aloe vera based primer (i use straight up aloe vera gel, it gets sticky which helps the makeup stick, while also protecting my skin) along with not wearing the makeup too heavily and not wearing it for too long, aswell as thoroughly washing your face and moisturizing afterwards, and giving your skin a few days between the times you wear makeup to rest and self-clean, while of course consistently washing it, by doing this i've found my acne to be decreasing and my skin to even look better the day after wearing makeup! and if you still want to wear makeup during your resting day, wearing some while avoiding skin products like foundation is completely safe, as long as you prep well and keep your skin as clean as possible! ❤
Yay, new video 😍 It's the middle of the night here (Finland) but I'm not waiting to watch this.
Hope you enjoyed it!
Always great to see content from the busiest cosmetic chemist on the internet
it's my first time watching your content. you are brilliant!!
these r my favorite videos
Glad you enjoy them! I really love making these 😊
thank you i do enjoy the tiktokery it is a pretty fun way to get educated about chemistry, the scientific method, product regulation, and all those fun things :)
Your channel is basically the only beauty channel I watch. I don't care much about skin care (except for sunscreen, cancer and stuff), but I find the insights into how skin care research works fascinating.
Edit: Even with only a Highschool chemistry education I called the lack of water in the vaseline pH test. Foolishness is really unbounded. 😆
It's almost as if acid-base reactions can't happen in a non-polar solvent like an oil based gel.
Thank you always for making these videos, they're very needed on all this sea of misinformation
We discussed this briefly on twitter once, yes, as medical students we do extensive pharmacology, and also toxicology, forensic medicine and epidemiology. There is no excuse for MDs to not understand "the dose makes the poison" or how to interpret studies. It's so disappointing.
I found myself… like, coming back to this video and just clicking it…. Or leaving it on with low volume…..
Thanks so much for being one of the few voices of reason!!!!! I know it must get exhausting and frustrating … but the hope you give me through knowing I am not alone is really priceless.

My favorite topic and my students will be able to follow!
I love your videos, my only disagreement is with the 'not killing your customers' being good business practice.
It is important to remember that a company is not run by a single person with a vested interest in the long term outcome of that company. As long as you don't kill the customer fast enough to raise any flags in the coming 30 or so years, whatever people are currently 'running' the company can safely retire before the company is ever put under scrutiny and slapped with fees that barely make a dent.
In that case, the problem would be leaks - the larger the company, the harder it is to keep a secret www.ox.ac.uk/news/2016-01-26-too-many-minions-spoil-plot

I am not very interested personally in beauty products but as a scientist and industrial manufacturing chemist I am greatly appreciative of the rigorous analysis you bring to discussions of these products. I am definitely going to have a read of the new developed methods for testing SPF (cuz I be that kind of nerd 🤣) but would love to see a video of you breaking down the general regulatory requirements and pros/cons within the industry when it comes to public safety/efficacy.
Thank Gaia you’re here! I really appreciate you sharing your knowledge it’s not just impressive. It’s also extremely needed. Thank you 🙏
Love your videos and healthy pragmatism
I laughed out loud multiple times while watching this video. God bless you.
Love the video. I can't however, look at it due to the camera focus jumping on and off the background, it's really visible on the tiny lights in the back. Listened to it as a podcast and it's really informational
39:48 the CSSC is the acronym in French (Comité scientifique pour la sécurité des consommateurs)
That would make sense... but then they have the title of the report in English? (I don't think they read it tbh)
Would love to hear your take on micro needling in a bottle
i can't comment again about how helpful and awesome michelle's videos are, it's too unoriginal. so i'll comment about the background. watch the twinkle lights on the left, they go in and out of focus, it's trippy!
For your whiteboard: maybe an easel could work? (Unless you want the surface to stay slanted) That way it would be at a more comfortable height, and be much more stable than a desk chair. However, it might take up too much space...
You could also potentially mount the whiteboard on a wall if you want it to stay in one spot?
I’m totally fine with you just holding the whiteboard up, but if you want a stand, the make good-quality-but-inexpensive collapsible stands that can hold whiteboards of that size. I have one in a desk drawer, in case I fill my wall-mounted whiteboard and briefly need extra space. They’re very handy because they’re really compact.
YESSS THESE ARE THE BEST
So, if I run out of sunscreen, I can just use use butter, since toast doesn't burn with butter spread on it. 😂😂😂
Michelle, it’s you against TikTok. I admire you so much! Thank you for all the work that you do. You inspire me to try to get to the cosmetic formulation industry to obliterate the “organic/clean/natural is better” movement! Get them!! Slaaaaay queen! lol
Thank you for making useful content that actually makes us smarter, so rare to find on youtube.
The only use I found for Yuka is having the inci list writen clearly, cuz damn you need to have perfect vision to read the labels on those cosmetic products.
Thanks for this fun video! People in the skincare community often refer to ascorbic acid as “pure” ascorbic acid to differentiate from its derivatives. Yet, we don’t say “pure” retinoic acid to differentiate from its alcohol or aldehyde precursors.
“Human skin is really cool but really annoying.” Human skin is so relatable 😂
My favorite whiteboard is standing behind something clear like glass or acrylic and writing on it however it'll look backwards when playing the video backwards. In post processing you can fix the error by mirroring the image.
The dermatologist in the last tiktoks works at a Florida medspa. Medspas always make me worry that they convince people to get treatments that don't actually work or are not worth the cost. I would love a video talking about the actual science behind skincare treatments at medspas.
Love your informative videos, Michelle! Perhaps using an iPad/tablet to drawing or screen-record can be helpful for making those visuals! Or you can project/print a photo and draw/label over it. Real-time drawings and labeling are especially helpful during my chemistry lectures, and perhaps would be helpful here as well!
