From a fellow scientist, it's so cool to see a video like this where you don't always talk about the main topic (retinol), but you also explain how scientific studies and publications work!! ❤🙏🏻
Loved the statement that “only ingredients with robust clinical evidence work” is bad science. I’ll always remember the joke that there’ve been no peer reviewed clinical trials that parachutes decrease your risk of death while sky diving.
“Parachute use did not reduce death or major traumatic injury when jumping from aircraft in the first randomized evaluation of this intervention. However, the trial was only able to enroll participants on small stationary aircraft on the ground, suggesting cautious extrapolation to high altitude jumps. When beliefs regarding the effectiveness of an intervention exist in the community, randomized trials might selectively enroll individuals with a lower perceived likelihood of benefit, thus diminishing the applicability of the results to clinical practice.” 😅👍
Oh my god, as a librarian your section on how to search for and understand a study gave me life! I've taught these research methodologies and evaluation techniques to so many undergrads and it just gives me such pleasure to see this out in the wild, as it were :) And in the interest of helping consumers make scientifically-informed decisions!

Retinol worked so well for me. My skin was a disaster before using it. Now, after 2 years I literally get compliments about my skin. However, it’s a long term solution and definitely requires consistency to work.
Right, I use one of the probably cheapest solutions with low % of retinol and love the results. After I finish this one surely will buy something with higher %
It was retinol and lactic acid for me. I am too young to tell whether or not it has prevented signs of aging but regardless of that, my skin is brighter and the texture is much smoother, and I hardly suffer significant breakouts anymore! It did also come with several lifestyle changes for me, though. Making sure I am hydrated, paying better attention to my diet, making sure I change my bedsheets more often, actually having a proper skincare routine where I previously did not have one... etc.
@@GodlessCogI can swear by lactic acid lotion (using amlactin). I'm already getting great lightening results and still improving four months using. I had done a chemical peel gone slightly wrong on my underarms three years ago, which left it dark brown (ironically, I was trying to lighten my black underarms). But my skin was too sensitive. I started this year with niacinamide cream but it kinda stopped working two months in using. But lactic acid is still steadily lightening the area!

Since I know some people will only watch the first few minutes of the video and end up thinking she’s saying the exact opposite of what she’s actually saying, here’s the summary: 14:30
I think a lot of people think being skeptical or going against the mainstream automatically makes them scientific. It's cool to doubt. I listened to an episode of a podcast that was all about debunking everything, and the host interviewed a dermatologist who'd written a book on how retinoids basically do almost nothing (I had a lot of moments where I really wish I could have directly posed some questions to the dermatologist because she didn't seem to be taking everything into account), and at the end, the interviewer smugly asks the dermatologist if she personally uses retinoids, obviously expecting she'd say "hell no!" But the dermatologist said she does use them, because they work a little!
I think that might be the podcast I referenced at the start 😅 Agree, there's a huge trend of edgy contrarian doctors at the moment ignoring all evidence beside clinical trial evidence, a few of the Science-Based Medicine writers have dubbed it "methodolatry" and it's a really interesting topic!
@@LabMuffinBeautyScience Oh, it reminded me of that podcast, but I wasn't sure! That was the first and only episode I listened to because the interviewer seemed like she wanted retinoids to be a scam because certain other skincare ingredients have been shown to be ineffective, so that must be applicable to all popular skincare ingredients. Methodolatry's a good term for it! People seem to like stuff to be disproven more than to actually do the work to figure out what's true.
Thank you so much for this video! It not only explains if, why and how retinol works but why and how science works. Clinical trials aren't the end all be all.
I've never been interested in cosmetics but this is such a thorough and interesting insight into it. I'm always delighted to be shown the hidden complexities behind a topic. This is the kind of quality most information should be! Congrats!
Would love to see a video breaking down what you actually do and don’t need to do in terms of skincare, it feels like so much is a very expensive scam, and you’re kind of left to figure it out. Would love a “these are basics that do in fact work and everyone should do” and “these are the additional steps that can address specific common issues” video, for the skincare fed-up people of the world!
What I like about you is that you’re not doing the typical “it works, trust me, bro” video. You actually encourage people to do their own research. Thank you!!
Girl, you rock! This was your best video, it was clear and the addition of humor was genius. I have wondered about the lack of well designed, double blinded skincare studies, especially on more than a handful of people. I knew it was about research funding, but I understand now that it’s more than just the money.
As someone in their 20s with acne prone skin, I believe that adapalene is superior to retinol. But that shouldn't be surprising☺️ I just wished it was available over the counter in the EU... It's difficult enough to find dermatologists without a long waiting list...
Loved the pin board part. Please do that again for other stuff or just upload it again all on its own and link to it whenever you want to explain why there are so few good peer reviewed cosmetic skin care studies
really good break down of why there isn't much high quality research into retinol and that things still can work without perfect evidence for it!! entertaining and informative
I taught high school science and spent countless lessons showing how to evaluate data in studies. Thank you for helping people see what’s behind the curtain.
I've been using retinol for almost 2 years now and my skin is FLAWLESS. Started at 23 (now 25) with Selfless by Hyram's retinol (0.2 + tranexamic acid + rainbow alge) for almost 1 year and half and now with Kiehl's retinol (0.3) x 3 times a week and i absooooooolutely don't regret it. Get yourself a Retinol, a moisturizer with Niacinamide and Ceramides to put on top, a Niacinamide, a Salicylic acid and a AHA serum for the rest of the week and BOOM! Bye-bye breakout, bye-bye lines, hello glass skin!
Tbh when I was that age I could have used everclear and vaseline and I wouldn't have lines... because, you know,of the age 😅 That being said, starting sun protection and good habits early is super important... especially the sun protection part. A lot of skin condition is still genetic and metabolic, and perfect routine might still not give perfect results to people with different baseline. Enjoy the effects, just don't overdo it.
I am seeing your video for the first time. It is very informative. Can you please make one based on latest serums and topical products actually using carcinogenic ingredients. That has me worried sick.
Michelle ur explanation and method to showing and presentation has improved over the years!! ☺️ It feels so easy to understand and know what’s going on around
Very interesting video, instant subscribe! My experience: I have been using Adapalene for over a year now daily before bed and I can say my skin looks so visibly different, it's evident without the need for scientific imaging for quantification and also discounting for some amount of "self-percention-distortion-via-placebo-effect". I never tried "typical cosmetic" Retinol, I went straight for the more druggy-variant. 😅
Actually enjoyed your easy to follow and clear explanation about evidenced based research as well. I wish more lecturers took your approach. Wonderful!
As a former research fellow, I really love it when scientists come out and interact with people. I honestly feel every scientist should be a content creator no matter what field of study they work in 😊
It breaks my heart how few viewers you have 😭 I want you to get that ad revenue so you can make more videos and I can put them on while I do chores and errands
Thank you so much! The biggest bottleneck is the research part, the dream would be to hire someone to help with that... in the mean time, if you aren't already aware of it, I did 2 seasons of a podcast called Skincare School with Adore Beauty!
As a self-proclaimed student learning about skincare and having the benefits using Tretinoin your channel has been significant about getting what is useful and what is wasteful in skincare. Thanks!
I spoiled myself when I scanned through the comments before getting to the evidence board segments, but I was still not prepared for the perfection that it is, communicating both the facts and the feeling. "That's not how companies think, they don't have skin." (6:48) encapsulates so much in this context and can be applicable in other circumstances as well.
3:19 Michelle I already had a ton of respect for you even before seeing good ol' Tim and, if ever you do a light-hearted analysis of storm that broadly relates it to cosmetic chemistry, I'd be one happy human being!
Can't even imagine the amount of time and effort you put into this, so thank you!! My skin still isn't sure yet if it likes retinoids in any form, but this helps clarify (as much as it can!) why it seems some OTC products seem stronger/more effective than others. Much to think about.
I noticed some wrinkles on my forehead forming a couple of months ago and immediately I started using retinol serum every night on my forehead and I see a big improvement. So for me it works 🤗🤗
@@SueRosalie nope, I always moisturized and had a routine before using retinol :) retinol serum is the only thing that changed and after using it for 6-7 months I see a difference
completely anecdotal experience here. I saw my parents at christmas time 2023, at which point i’d been using this ingredient for about 2-3 weeks, so too early for it to have made any difference. Fast forward to when i saw them next in May ( so roughly 6 months of using) and the first thing my mum said to me when she saw me was ‘what have you had done? you look 5 years younger’. my routine had barely changed apart from 1 thing. Adapalene 0.1% gel. Nothing else really changed, broadly the same cleansers, serums, moisturisers and spf. So for me personally i absolutely believe retinoids do work with consistent use
In Japan, there is a quasi drug class that a lot of skincare is in where it's not like a medicine, but it is acknowledged to be something with a strong effect such as a vitamin C product. What do you think about this?
i feel like i was watching a PBS program for teens, like BizKids, as you was "breaking knowledge down" in front the cork board ...very fun, informative, and nostalgic.
Haven’t finished the video yet but the cutaway to the conspiracy board + “as a person who owns skin” sent me😂 Also love how thorough your explanations are of how clinical trials and studies work!
What about retinol alternatives like bakuchiol? I've been seeing bakuchiol pop up a lot lately including in creams that are priced higher than some expensive retinol creams. My face doesn't react will with retinol so I'm curious about this particular alternative and others night cream alternatives that are promising. I love how thorough and informative your videos are. Thank you for sharing and making it entertaining!
Thanks for this video. I have been using retinol and many other serums and aha bha peeling solutions for 2 years aged 38 years, 6 months. People tell me, that I look better and my skin looks flawless. But again, I have a healthy lifestyle, very balanced diet too. I drink 4 to 5 litres of water.
Definitely does, nothing else helped my acne for years until I started trying various retinol. I didn't love tretinoin from gp as my skin was so dry if I smiled I felt it split. But I got one for very dry skin from paula's choice and it's slower to work but is healing my skin so well
I SWEAR to god I used differen gel for YEARS to clear my cystic acne. It worked a treat, now I use a serum with bakuchiol and encapsulated retinol and it works the same as the differen gel did on my acne. It also gets rid of dark spots from sun damage.
Weaker retinoids are great for young people to prevent weakening of the skin, and they are anti-microbial. Even cheap retinoids can prevent some acne and likely to prevent infections. Retinol is also now being used as an antibiotic alternative to treating MRSA/other resistant skin infections. As a MRSA carrier, I can confirm even lower end retinoid moisturizers can go a long way in treating mild infection and preventing infections altogether. You need moisturizer for skin infections, despite the common belief that you need to let them dry out.
Great video. This echoes my experience with retinol, retinaldehyde, and tretinoin, as well: I've used all three, and they all produce the same result on my skin. Tretinoin just works a bit faster but is also more finicky to use in terms of dosing. And while any retinoid can make me ruddy-looking if I overuse it, tret can sometimes have this effect overnight from one use, so I still keep retinaldehyde on hand to swap in for tretinoin if I have an important event the next day and don't want to risk looking sunburned.
Yes, I have the exactly same experience as you. Retinoids works really well for me. I can feel the difference in my skin (really quickly) when I stop using.
Wow, it’s good to know that all forms of retinoids provide the same results in the long term. I have sensitive skin so I can only tolerate retinol, but I’ve been feeling like I’m missing out for not using tretinoin. Your comment gives me the reassurance that retinol is just as good as long as I stay consistent.
@@nado5918 there's variation between individuals due to enzyme polymorphism (thanks to @moskinlab for that terminology 😁), so my skin may just be unusually good at metabolizing retinol and retinaldehyde. I'm also only using retinoids for preventative antiaging and not to treat a medical condition or severe photodamage. But yes, on my skin, they all get to the same endpoint, the difference is just speed. I also have sensitive skin (DSNW in the Baumann system), and I think a lot of people who make pronouncements like "tret daily or bust" don't realize they have resistant skin and won't understand our skintype. Especially if you've tried tret and weren't able to tolerate it at any strength or frequency of application, I think it's fine to stick with nondrug retinoids like retinaldehyde or retinol. The alternative of leaving your skin in a perpetually irritated state just so you can say you're using tret isn't really sustainable long-term: you'll wind up with an even more impaired skin barrier which can paridoxically make your skin look worse or even "older" until it's healed.
@@n.m.3995 you may be unusually sensitive to one of the retinoids in the product or to something in the vehicle. Have you experienced such a reaction with other retinoid products?
I really liked this video! I think personally, that this means one of the main issues is a lack of nationalised skincare companies and it being one of the most privatised industries. The main goal is profit, and paying lots of money for good quality clinical trials would only benefit the consumers. Obviously in a system where profit is the main drive, and their consumer base isn't usually that well versed in analysing skincare in a material way, that's not going to happen. I understand this, but I think that also we have to remember that them doing studies and keeping the results a secret, doesn't mean that people should accept that as any kind of guarantee their stuff works. In a situation where an ingredient has no good quality clinical trial published to a reputable journal, they basically have shown no high-quality evidence to back up their claims to the public. So, I think we should still be very skeptical of cosmetic company claims in general - however, I understand that for retinol it's a bit different. I wouldn't lump in academic researchers and heavily funded research by massive pharma companies with a long history of corruption. There is obviously a conflict of interest, that standard exists for a good reason. It's not a conspiracy theory to practice critical thinking regarding that. When it's also backed up by consistent good academic research/publically funded research, then it's higher quality. Until then, it's disputed/ongoing. Of course, that doesn't mean it doesn't work, the sound reasons for the lack of good-quality clinical trials are like you explained! 👏
Overall, I personally think retinol works to improve your skin. I don’t think it’s a miracle ingredient, but I think once you get over the adjustment period, your skin looks better overall.
Ive seen improvements in my skin since using a prescription tretanoin cream. Its been a ride! After a year, my skin still gets dry despite layering with plenty of moisturiser. I skip a night or two when that happens. I genuinely do see an improvement. It's a long game. Retinol isn't as strong as prescription strength tretanoin. Interesting video. Love your channel ❤️
I did one on LAA but the one on derivatives is taking a while, partly because of the stuff I explained here - a lot of the data is supplier data and it's a mess to sort through! 😭 It'll happen
@@LabMuffinBeautyScienceI’m excited for this! I actually rewatched your LAA video a couple of weeks ago and looked for the followup on derivatives, and thought you’d maybe just moved on from it- I’m excited that it’s coming!
From my own experience, a month after adding retinol to my routine, I've had people I know notice and ask me what I had done to my skin, without me saying anything. Do with it what you want
There was something on the skincare subreddits recently about the retinol in Paula's Choice and The Ordinary products being unstable or rapidly degrading. So, even if retinol does work, that's another thing I don't want to worry about. Also worth noting that prescription retinoids typically come in airtight metal tubes instead of airless pumps or dropper bottles.
I don't know about retinol, but I found tret made my skin look better in terms of acne and hyperpigmentation. Seriously, 10/10 for curology on only .01%. That low percent is necessary because my first derm demolished my skin by prescribing a multitude of harsh products, and I started off with sensitive skin in the first place. But tret also made my skin so *shiny* . I just couldn't take looking like a walking oil bomb while my skin wss 100% dry to the touch. On top of that, I felt like it honestly made me look...older? I can't explain it, but my skin was baby smooth, shiny and aged. So I don't care about the research in the I case. My skins good on hyaurolinic acid cream, sunscreen and moisturizing cleansers.
I've heard the main reasons for looking older on tret is when it's too dry and irritating as those factors will show wrinkles more. Slow and steady is how I'm approaching prescription retinols (percentage wise).
Super interesting video, I've learned a lot, thank you! I didn't know, for example, that retinoids had two different categories. I, personally, prefer adapalene over retinol. I've tried both and adapalene had less side effects on me and provided the same results.
9:18 btw this is what lisa eldridge did, she tested using her cleanser against nothing and then showed hydration levels. It could entirely be down to the water and not her cleanser and that is not mentioned but the "clinical trial results" are mentioned so many times in her marketing
I tried the special retinol eyecream from the Inkey list because I have hyperpigmentation and strange texture around my eyes. I tried it over a period of 4 to 6 months, skin was just constantly scabbing and dry. At first I thought this was fine, surely it meant my skin was renewing. But I figured that after a while my body would get used to it and adjust. It didnt. I just had dry scabby even more textured skin on my eyes that was still hyperpigmented. When I stopped the dry skin went away in a week. Retinols do seem to do something on my skin, but I wouldn't say its positive
This was such a good refresher on how the Availability bias can make us ignore good evidence! I am really curious about these newer methods of testing... It sounds like chemists are able to somehow reverse engineer effects based on multiple different studies?
Great video! As a life altering sufferer of many underfunded, undereaserched and critically poorly treated diseases, I honestly couldn't give two shits about whether anti aging skin care has been rigorously tested. 😅 Just food for thought.
I feel you on the underfunded diseases. It's infuriating. I had doctors tell me adenomyosis is impossible unless you've given birth , yet when I finally found a surgeon specialist not only did I have endometriosis as we suspected but yep, I had nasty adenomyosis!
@@foxwaffles Ugh that's ridiculous - my excision surgeon told me adenomyosis and endometriosis go hand in hand, it's basically impossible to have moderate endo and not have some adenomyosis, and that he'll see me in 10 years to yeeterus. But yay for specialists who know their stuff!
@@LabMuffinBeautyScience omg no way!!! Thanks for sharing 😮 I had to travel out of state to see an endo specialist but it was ultimately the best decision for me. I wanted a hysterectomy and let him know during the pre-op consultation and he didn't argue or say no, he said generally speaking we have thought about it a lot already and he trusts his patients know what they want. Post op he was like you made a good call on that 😅
you are a god send !! thank you for spreading knowledge. i was so close to being duped into changing up all the new things i am trying which realisticly have had good results if i ignore the fear monger like im gonna be a half a man from estrogen overload

Girl, you rock! This was your best video, it was clear and the addition of humor was genius. I have wondered about the lack of well designed, double blinded skincare studies, especially on more than a handful of people. I knew it was about research funding, but I understand now that it’s more than just the money.
I was really impressed by logic and reasoning in this video even tho i as a man barely use any skin care products.
As someone in their 20s with acne prone skin, I believe that adapalene is superior to retinol. But that shouldn't be surprising☺️ I just wished it was available over the counter in the EU...
It's difficult enough to find dermatologists without a long waiting list...
Loved the pin board part. Please do that again for other stuff or just upload it again all on its own and link to it whenever you want to explain why there are so few good peer reviewed cosmetic skin care studies
really good break down of why there isn't much high quality research into retinol and that things still can work without perfect evidence for it!! entertaining and informative
I taught high school science and spent countless lessons showing how to evaluate data in studies. Thank you for helping people see what’s behind the curtain.
I've been using retinol for almost 2 years now and my skin is FLAWLESS. Started at 23 (now 25) with Selfless by Hyram's retinol (0.2 + tranexamic acid + rainbow alge) for almost 1 year and half and now with Kiehl's retinol (0.3) x 3 times a week and i absooooooolutely don't regret it. Get yourself a Retinol, a moisturizer with Niacinamide and Ceramides to put on top, a Niacinamide, a Salicylic acid and a AHA serum for the rest of the week and BOOM! Bye-bye breakout, bye-bye lines, hello glass skin!
This sounds like a good regimen 👍
That sounds being 25🤷🏻♀️
@@betito5192 😂😂😂😂 come back to us after 10 years and kids
genuinely dont know what you are talking about, are you trying to say that all young people have glass skin?@@betito5192
Tbh when I was that age I could have used everclear and vaseline and I wouldn't have lines... because, you know,of the age 😅 That being said, starting sun protection and good habits early is super important... especially the sun protection part. A lot of skin condition is still genetic and metabolic, and perfect routine might still not give perfect results to people with different baseline. Enjoy the effects, just don't overdo it.
The Latrice Royale's 5G reference blew me away. I really love this channel 💜
This video was awesome! As a psych student I loved the deep dive into research in the industry (or lack thereof)
I am seeing your video for the first time. It is very informative. Can you please make one based on latest serums and topical products actually using carcinogenic ingredients. That has me worried sick.
Your content is so so so amazing! Never get tired of watching your videos!
Michelle ur explanation and method to showing and presentation has improved over the years!! ☺️ It feels so easy to understand and know what’s going on around
Very interesting video, instant subscribe! My experience: I have been using Adapalene for over a year now daily before bed and I can say my skin looks so visibly different, it's evident without the need for scientific imaging for quantification and also discounting for some amount of "self-percention-distortion-via-placebo-effect". I never tried "typical cosmetic" Retinol, I went straight for the more druggy-variant. 😅
Yep I just started adapalene and had retinization, so I guess that's my sign that it's working
@@manojipereira9169what is retinization?
yeah it took me a year, but my acne never came back
I did too. Why would I pay so much money for something less effective?
Actually enjoyed your easy to follow and clear explanation about evidenced based research as well. I wish more lecturers took your approach.
Wonderful!
Thank you very much!
I am only part way through this video and I’m enjoying it even more than I thought I would. Your creative and teaching skills are ⭐️⭐️⭐️⭐️⭐️
I definitely appreciate this scientific approach to explaining things, definitely has some degree of confidence in trying it now.
You've done it again Doc - one of your best to-date!
thanks for the time, effort, drawings and humour you put into edumucating us!
As a former research fellow, I really love it when scientists come out and interact with people. I honestly feel every scientist should be a content creator no matter what field of study they work in 😊
this was such a good and refreshing video. the effort and passion you put into these really shows. thank you!
Thank you so much!
I am Impressed youre one of the few who actually Critisize Studies and not blindly use them.
Thnak you so mich its a instant sub
Yay! I was so hoping you'd cover the Sci VS. pod. This was a great video
It breaks my heart how few viewers you have 😭
I want you to get that ad revenue so you can make more videos and I can put them on while I do chores and errands
Thank you so much! The biggest bottleneck is the research part, the dream would be to hire someone to help with that... in the mean time, if you aren't already aware of it, I did 2 seasons of a podcast called Skincare School with Adore Beauty!
Loved this video! Especially the cork board 😂 can’t wait to see more about retinoids 👀
Coming soon! (hopefully)
You’re my new favorite RUclipsr. Just discovered your channel, and now I must binge-watch all your content. You’re amazing! 🙌🏾
As a self-proclaimed student learning about skincare and having the benefits using Tretinoin your channel has been significant about getting what is useful and what is wasteful in skincare. Thanks!
What a little masterpiece of a video. SO GOOD.
I appreciate that your conclusion is ultimately: probably.
I spoiled myself when I scanned through the comments before getting to the evidence board segments, but I was still not prepared for the perfection that it is, communicating both the facts and the feeling. "That's not how companies think, they don't have skin." (6:48) encapsulates so much in this context and can be applicable in other circumstances as well.
3:19 Michelle I already had a ton of respect for you even before seeing good ol' Tim and, if ever you do a light-hearted analysis of storm that broadly relates it to cosmetic chemistry, I'd be one happy human being!
Can't even imagine the amount of time and effort you put into this, so thank you!! My skin still isn't sure yet if it likes retinoids in any form, but this helps clarify (as much as it can!) why it seems some OTC products seem stronger/more effective than others. Much to think about.
10/10 on informativity, delivery, humor ...and lowkey looking super hot while being unhinged
instantly subbed
I noticed some wrinkles on my forehead forming a couple of months ago and immediately I started using retinol serum every night on my forehead and I see a big improvement. So for me it works 🤗🤗
you're likely just getting the benefits of moisturisation and paying attention to a regular routine
@@SueRosalie nope, I always moisturized and had a routine before using retinol :) retinol serum is the only thing that changed and after using it for 6-7 months I see a difference
I break out sometimes if I use too much, but it’s helping my forehead as well
completely anecdotal experience here. I saw my parents at christmas time 2023, at which point i’d been using this ingredient for about 2-3 weeks, so too early for it to have made any difference. Fast forward to when i saw them next in May ( so roughly 6 months of using) and the first thing my mum said to me when she saw me was ‘what have you had done? you look 5 years younger’.
my routine had barely changed apart from 1 thing. Adapalene 0.1% gel. Nothing else really changed, broadly the same cleansers, serums, moisturisers and spf. So for me personally i absolutely believe retinoids do work with consistent use
In Japan, there is a quasi drug class that a lot of skincare is in where it's not like a medicine, but it is acknowledged to be something with a strong effect such as a vitamin C product. What do you think about this?
i feel like i was watching a PBS program for teens, like BizKids, as you was "breaking knowledge down" in front the cork board ...very fun, informative, and nostalgic.
Haven’t finished the video yet but the cutaway to the conspiracy board + “as a person who owns skin” sent me😂 Also love how thorough your explanations are of how clinical trials and studies work!
What about retinol alternatives like bakuchiol? I've been seeing bakuchiol pop up a lot lately including in creams that are priced higher than some expensive retinol creams. My face doesn't react will with retinol so I'm curious about this particular alternative and others night cream alternatives that are promising. I love how thorough and informative your videos are. Thank you for sharing and making it entertaining!
I got my health and body totally screwed by retinoids. I wish someone told me that the symptoms caused by it will last forever and will be so harsh.
Thanks for this video. I have been using retinol and many other serums and aha bha peeling solutions for 2 years aged 38 years, 6 months. People tell me, that I look better and my skin looks flawless. But again, I have a healthy lifestyle, very balanced diet too. I drink 4 to 5 litres of water.
Definitely does, nothing else helped my acne for years until I started trying various retinol. I didn't love tretinoin from gp as my skin was so dry if I smiled I felt it split. But I got one for very dry skin from paula's choice and it's slower to work but is healing my skin so well
Being a science nerd, I love this kind of thing. I enjoy learning the science behind why things work the way they do. This was super informative!
Good timing. I just heard this come up recently in some comment sections. Most seem to say tretinoin is the only thing that works.
I SWEAR to god I used differen gel for YEARS to clear my cystic acne. It worked a treat, now I use a serum with bakuchiol and encapsulated retinol and it works the same as the differen gel did on my acne. It also gets rid of dark spots from sun damage.
Weaker retinoids are great for young people to prevent weakening of the skin, and they are anti-microbial. Even cheap retinoids can prevent some acne and likely to prevent infections. Retinol is also now being used as an antibiotic alternative to treating MRSA/other resistant skin infections. As a MRSA carrier, I can confirm even lower end retinoid moisturizers can go a long way in treating mild infection and preventing infections altogether. You need moisturizer for skin infections, despite the common belief that you need to let them dry out.
I loved that you used the Tim Minchin piece from Storm. It was such a nice surprise 😆
Great video. This echoes my experience with retinol, retinaldehyde, and tretinoin, as well: I've used all three, and they all produce the same result on my skin. Tretinoin just works a bit faster but is also more finicky to use in terms of dosing. And while any retinoid can make me ruddy-looking if I overuse it, tret can sometimes have this effect overnight from one use, so I still keep retinaldehyde on hand to swap in for tretinoin if I have an important event the next day and don't want to risk looking sunburned.
Yes, I have the exactly same experience as you.
Retinoids works really well for me. I can feel the difference in my skin (really quickly) when I stop using.
Wow, it’s good to know that all forms of retinoids provide the same results in the long term. I have sensitive skin so I can only tolerate retinol, but I’ve been feeling like I’m missing out for not using tretinoin. Your comment gives me the reassurance that retinol is just as good as long as I stay consistent.
@@nado5918 there's variation between individuals due to enzyme polymorphism (thanks to @moskinlab for that terminology 😁), so my skin may just be unusually good at metabolizing retinol and retinaldehyde. I'm also only using retinoids for preventative antiaging and not to treat a medical condition or severe photodamage.
But yes, on my skin, they all get to the same endpoint, the difference is just speed. I also have sensitive skin (DSNW in the Baumann system), and I think a lot of people who make pronouncements like "tret daily or bust" don't realize they have resistant skin and won't understand our skintype.
Especially if you've tried tret and weren't able to tolerate it at any strength or frequency of application, I think it's fine to stick with nondrug retinoids like retinaldehyde or retinol. The alternative of leaving your skin in a perpetually irritated state just so you can say you're using tret isn't really sustainable long-term: you'll wind up with an even more impaired skin barrier which can paridoxically make your skin look worse or even "older" until it's healed.
I need Help. I use the inkey list retinol serum.
It Hurts on my skin. Why?
@@n.m.3995 you may be unusually sensitive to one of the retinoids in the product or to something in the vehicle. Have you experienced such a reaction with other retinoid products?
I really liked this video! I think personally, that this means one of the main issues is a lack of nationalised skincare companies and it being one of the most privatised industries. The main goal is profit, and paying lots of money for good quality clinical trials would only benefit the consumers. Obviously in a system where profit is the main drive, and their consumer base isn't usually that well versed in analysing skincare in a material way, that's not going to happen. I understand this, but I think that also we have to remember that them doing studies and keeping the results a secret, doesn't mean that people should accept that as any kind of guarantee their stuff works. In a situation where an ingredient has no good quality clinical trial published to a reputable journal, they basically have shown no high-quality evidence to back up their claims to the public. So, I think we should still be very skeptical of cosmetic company claims in general - however, I understand that for retinol it's a bit different.
I wouldn't lump in academic researchers and heavily funded research by massive pharma companies with a long history of corruption. There is obviously a conflict of interest, that standard exists for a good reason. It's not a conspiracy theory to practice critical thinking regarding that. When it's also backed up by consistent good academic research/publically funded research, then it's higher quality. Until then, it's disputed/ongoing. Of course, that doesn't mean it doesn't work, the sound reasons for the lack of good-quality clinical trials are like you explained! 👏
Overall, I personally think retinol works to improve your skin. I don’t think it’s a miracle ingredient, but I think once you get over the adjustment period, your skin looks better overall.
Ive seen improvements in my skin since using a prescription tretanoin cream. Its been a ride! After a year, my skin still gets dry despite layering with plenty of moisturiser. I skip a night or two when that happens. I genuinely do see an improvement. It's a long game. Retinol isn't as strong as prescription strength tretanoin. Interesting video. Love your channel ❤️
Thank you! 😀 Please also do a similar video about if vitamin C (and all it's 1 000 000 different forms) actually work.
She's done it before
I did one on LAA but the one on derivatives is taking a while, partly because of the stuff I explained here - a lot of the data is supplier data and it's a mess to sort through! 😭 It'll happen
@@LabMuffinBeautyScienceI’m excited for this! I actually rewatched your LAA video a couple of weeks ago and looked for the followup on derivatives, and thought you’d maybe just moved on from it- I’m excited that it’s coming!
Love this!! You could make a whole scientific article just to talk about this and publish it
From my own experience, a month after adding retinol to my routine, I've had people I know notice and ask me what I had done to my skin, without me saying anything.
Do with it what you want
This video is fantastic! High quality scientific communication 👏
There was something on the skincare subreddits recently about the retinol in Paula's Choice and The Ordinary products being unstable or rapidly degrading. So, even if retinol does work, that's another thing I don't want to worry about. Also worth noting that prescription retinoids typically come in airtight metal tubes instead of airless pumps or dropper bottles.
Yep, I'll be discussing those points and more in the next video! 😁
how dare they
What's wrong with airless pumps?
I have a prescription retinoid in an pump bottle. www.aklief.com/content/images/product-packaging-desktop.jpg
can i see that reddit thread
took me back to those chem classes oh my god MISSED THIS Michelle :( the way you communicate AMAZING.
Skincare, science AND Tim Minchin clips in the same video? Yes please thank you.
😀
OMG I want to hire you as a lecturer to teach the students at my state university adademic techniques SO HARD. DAMN, GIRL! 😍😍😍
I don't know about retinol, but I found tret made my skin look better in terms of acne and hyperpigmentation. Seriously, 10/10 for curology on only .01%. That low percent is necessary because my first derm demolished my skin by prescribing a multitude of harsh products, and I started off with sensitive skin in the first place. But tret also made my skin so *shiny* . I just couldn't take looking like a walking oil bomb while my skin wss 100% dry to the touch. On top of that, I felt like it honestly made me look...older? I can't explain it, but my skin was baby smooth, shiny and aged. So I don't care about the research in the I case. My skins good on hyaurolinic acid cream, sunscreen and moisturizing cleansers.
I've heard the main reasons for looking older on tret is when it's too dry and irritating as those factors will show wrinkles more. Slow and steady is how I'm approaching prescription retinols (percentage wise).
You are doing gods honest work explaining to lay people how to evaluate scientific papers
Super interesting video, I've learned a lot, thank you! I didn't know, for example, that retinoids had two different categories. I, personally, prefer adapalene over retinol. I've tried both and adapalene had less side effects on me and provided the same results.
Thanks! This is so amazing to hear. You’re the only person I trust when it comes to skin care!
This is suuuch a well-done video!!
I wish gubermint cared more about skin too 😖
Thank you so much! 🥰
I used retinol for sensitive skin and it still made my skin more sensitive.
9:18 btw this is what lisa eldridge did, she tested using her cleanser against nothing and then showed hydration levels. It could entirely be down to the water and not her cleanser and that is not mentioned but the "clinical trial results" are mentioned so many times in her marketing
I tried the special retinol eyecream from the Inkey list because I have hyperpigmentation and strange texture around my eyes. I tried it over a period of 4 to 6 months, skin was just constantly scabbing and dry. At first I thought this was fine, surely it meant my skin was renewing. But I figured that after a while my body would get used to it and adjust. It didnt. I just had dry scabby even more textured skin on my eyes that was still hyperpigmented. When I stopped the dry skin went away in a week. Retinols do seem to do something on my skin, but I wouldn't say its positive
Did u use moisturiser? Hydration? Hada labo works with retinol for me.
@@Paralianpoet I did, it just wasnt for me
you need to use moisturizer with retinol
I ordered you book. Well done for your channel
“….as someone who owns skin…” priceless!
This was such a good refresher on how the Availability bias can make us ignore good evidence! I am really curious about these newer methods of testing... It sounds like chemists are able to somehow reverse engineer effects based on multiple different studies?
Great video! As a life altering sufferer of many underfunded, undereaserched and critically poorly treated diseases, I honestly couldn't give two shits about whether anti aging skin care has been rigorously tested. 😅 Just food for thought.
Completely agree! It's so frustrating to see the chronic underfunding of research for particular diseases.
I feel you on the underfunded diseases. It's infuriating. I had doctors tell me adenomyosis is impossible unless you've given birth , yet when I finally found a surgeon specialist not only did I have endometriosis as we suspected but yep, I had nasty adenomyosis!
@@foxwaffles Ugh that's ridiculous - my excision surgeon told me adenomyosis and endometriosis go hand in hand, it's basically impossible to have moderate endo and not have some adenomyosis, and that he'll see me in 10 years to yeeterus. But yay for specialists who know their stuff!
@@LabMuffinBeautyScience omg no way!!! Thanks for sharing 😮 I had to travel out of state to see an endo specialist but it was ultimately the best decision for me. I wanted a hysterectomy and let him know during the pre-op consultation and he didn't argue or say no, he said generally speaking we have thought about it a lot already and he trusts his patients know what they want. Post op he was like you made a good call on that 😅
YEETERUS 😂🙏
you are a god send !! thank you for spreading knowledge. i was so close to being duped into changing up all the new things i am trying which realisticly have had good results if i ignore the fear monger like im gonna be a half a man from estrogen overload
So interesting and informative. Thank you for teaching us.
Loved the Wu Tang reference, just had to pause before I watched the rest 💛
Loved the crazy scientist vibe.you're my only trusted source of all things skin❤
Another fantastic video, thank you for sharing your knowledge!
