Why can't most dermatologists be like you? Your in-depth explanations are amazing!
Wow! I'm still "absorbing" the sunscreen lesson. Lots to understand.. One thing is for sure, I/we couldn;t have done any of this with you: telling, showing, reminding, and teaching us! Love ya, Dr. Dray AKA Dr. Sunscreen!
Thanks!! Glad the videos are helpful. Have a fabulous Friday!
Help! I just applied 1 teaspoon of my Cerave AM, I've been using about 1/2 teaspoon, and I can hardly tolerate it. It's so much that I feel almost suffocating with that much. What do I do? Apply it in two steps? It's hot here and I'm sweating buckets!!! :(
M Cpay try another sunscreen

I was wondering if you answer a question? I found a foundation with SPF 23 (titanium dioxide) and I was curious if this is a high enough SPF or if I should layer it with another SPF? Right now I am using the DRMTGLY tinted SPF 45. My instinct tells me that SPF 23 is too low, but I want sure. Thanks for any help!
THANK YOU SO MUCH for the whole series Andrea, I am sharing with family and friends, it is still so hard to truly change behaviours and educate ourselves in this area!
the part with avobenzone, and titanium dioxide accelerating its rate of degradation, as well as the discussion around the insufficiency of titanium dioxide in mineral makeup (powder forms) to protect the skin is highly appreciated. thank you so much Dr. Dray!
Thank you for breaking down the proper use of sunscreens. I watch your videos everyday while I eat my beakfast and really enjoy all of the tips for effective skin care.
I have done nothing this weekend but binge watch all your videos!! I've watched hours and hours of your videos! You are my new fave!
You should get a life
blisterpacman
no u
I didn't realize that Titanium Dioxide affected Avobenzone. Always learning something new watching your videos. Thanks for all the information!
Yeah it is a subtle point for sure!
omg i've been layering a moisturiser with spf followed by my sunscreen for years and never knew that i should check this!! and i thought i was being so good doubling up on my sun protection :(
but the altruist sunscreens have avobenzone and titanium dioxide in its ingredients
@@theclassicalgirl Tinosorbs stabilize avobenzone
@@euphrasiepolly5575 does that mean they are safe to use under make up that has titanium dioxide in its ingredients?
I haven't watched for a week, now I'm back! you're glowing dr dray!
Jijie Forsythe thanks so much for your sweet comments and I hope you are having a great day 😊
Such an excellent series this has been! I wish everyone would watch this. There are many beauty RUclipsrs that rely on makeup as their sunscreen, use brush on powder sunscreen as their only sunscreen or apply such a small amount of sunscreen. Thanks Dr. Dray!
Thanks!!
Dr Dray, you are awesome! Thank you so much for sharing your knowledge and wisdom.
can you do a video on how to reapply sunscreen over makeup or BB cream? with recommendations? thank you!
I love being able to watch a video and feel like I learn something you explain things so well thank you sending out Good Vibes and positive energy
Thanks Ms Kelly! Hope you are having a happy Friday :)
thank you for the helpful video!! literally watched a terrible sunscreen video before this, raising so many questions of mine.. thank you for the practical answers!!
Another great vlog Dr. Dray! Loved the Sunscreen series. Enjoy your weekend😊
Thanks so much Ms Julie! Hope you are having a great night :)
yay I'm first. thanks for taking the time to simplify things for us doc.. I had no idea sunscreens were tested in this way.. have a fantastic weekend!
Thanks!! Hope you have a great weekend :)
Thank you, Dr Dray. I always enjoy and learn from your videos. Have a great day !
thank you so much Ms Beth and you too have a great day :)
Most informative video on SPF!! Thank you!
Thanks for the teaspoon analogy, that is helpful. Also didn't realize that about titanium dioxide, and I think I've layered before!
Thanks Ms Sherry! Glad the q&a was helpful. Have a great friday night :)
Very informative video. I didn't know that about Avobenzone & Titanium Dioxide. You made some really good points.
Thanks Ms Jackie! Hope you are having a great night!!
Great insight /excellent session. Thank you for this video. Info about avobenzone and titanium dioxide is a eye opener.
Happy Friday, Dr. Dray! I've really appreciated this series, and (thanks to your recommendations!) have finally found a couple of sunscreens that I can comfortably wear with or without makeup. Love the Cerave one, as well as the Neutrogena clear skin. I'm getting ready to try the Australian Gold 50 Tinted one that many others have praised. BTW, for others like me who have not been able to find the AG 50 tinted anywhere, I found it at CVS yesterday quite by accident, I was looking for something else, and spotted it on the bottom shelf with face moisturizers (not with sunscreens). Have a great weekend!
Thanks so much Ms Susan! Glad you found some sunscreens you like and hope you have a happy friday :)
I can't comment on every vid, but I want to say thank you for all the information. Keep being on RUclips please.
I am so happy to hear you enjoy!
Thank you! I've learned so much from your videos. I picked up the Elta MD physical sunscreen that you use too, and am hopeful that it'll work out for me!
Thanks Ms Ruth!!
Well, sun (!) of a gun. I wear SPF 50 every day, but I rarely reapply and thought the lack of redness meant my sunscreen had protected me from skin damage. You very clearly explained how wrong I was. I've been enjoying your videos for a couple of months and thought "reapply-30" was a little overboard, but this video finally made me understand why I need to be reapplying sunscreen. You definitely just made a difference in my sunscreen habits. Thank you!
Ann Oglesby thank you so much 😊
I have to watch this vid again today to make sure of what I have learned about sunscreen from you so far. The reason is I came across this vid of 2 beauty bloggers (my favorite ones) who still claim SPF indicates the time our skin is protected from UVB using sunscreen. All the things they say are reasonable enough (types, ingredients and reviews) except the one thing above. I was a bit disappointed cause they know all that but then give the wrong info of a basic term. Information sources are important and I trust you Dr Dray.
that is not correct
Oh man! I thought I was doing so well with wearing Neutrogena ultra sheer spf 50 in combination with EltaMd tinted sunscreen. I am on Retin A as well. I really hope I haven't being doing any UVA damage :( :( Thanks so much for this information!!! Best RUclipsr around!
Well the elta md should cover you just fine for the uva component....the cautionary tale is with the mineral powders that don't evenly distribute sun protection
thanks Ms Jennifer!
10K!! Yay! Edited to say thank you and that I've learned so much from you.
vcowan1122 thank you so much for your sweet comments and support 🙂
Thank you for your commitment to educating so many of us on skin care routines and products. Watching your videos the last several months, I've learned so much and my focus on sunscreen has improved significantly as a result. In rewatching the sunscreen videos, I have a question about layering. You mentioned avebenzone is degraded with titanium dioxide. I often vary applications between chemical and physical sunscreens during the day. If I use chemical in the morning and reapply with physical, wouldn't the physical sunscreen application still protect me against UVA regardless of how the titanium dioxide affects the avebenzone filter applied earlier in the day?? I'm sorry for being obtuse, but I didn't understand your point here. Thanks in advance for providing additional clarification when layering sunscreens throughout the day. (And...congrats on fast approaching the 100k subscriber mark!! Well Done!)
ti can, in theory, degrade the avobenzone faster...but in reality, it doesn't seem to make a difference as studies do show that the combination of mineral and chemical filters still lower amount of skin cancers and sun damage
Wow! Lots of great information! 😎. Thank you Dr.😁
Thanks Ms Nancy! Hope you are having a great night :)
Great knowledgeable video. Thanks for this.
SO GLAD I FOUND YOU :) You're amazing! Hope you see this. QUESTION1: Can you do a video on melanin? Reason why I've always been a sunscreen advocate myself is cuz I felt I've always "sunburned" and got dark easily. (Ironic, given my name, Melanie.) I'd love to hear your breakdown of different skin types and their solutions. Leading to my next question. QUESTION2: How do I reapply sunscreen on a daily basis if I am wearing a full face of make up?? (Yes, I am trying to wear less make up but I'm stuck between a rock and a hard place with wanting max SPF coverage and makeup to cover acne scars and active acne.. ) Regardless, I want to be protected EVERY DAY, but you mentioned powder sunscreen isn't really effective. :( For a second, I thought that was my solution. PLS HELP!
Thank you for your thorough reviews!!! Could you please give your opinion on Devita solar protective moisturizer 30
Would love it if you addressed the issue of dentured alcohol in face sunscreen in a Q and A. All my favourites contain it high on the ingredients list, and everything I read says its the worst thing to put on my face in terms of aging.
While I have no issue with getting older, I don't want to use products that are actively aging my skin and would love your balanced advice.
I love your sense of humour and look forward to your posts every day.
Rhona Reason ignore that please! There is NO evidence to support that denatured alcohol is "bad" and in fact it is needed for the sunscreen filters to work properly
Thank you so much. It's so difficult to sort fact from fiction without getting lost in all the bogus science out there.
You are owing such a great job in keeping it real and keeping us informed.
Thanks again.
Sorry should read "doing".
Great Video! Your just Amazing! You are truly helping so many people with your knowledge. I think that is such a beautiful thing. Love and Light💖Carli Oh BTW: You have the best eyebrows!
Thank you so much for your sweet comments and compliments! Hope you are having a great night :)
Can anyone answer me, I wanna know about cerave "AM moisturizing lotion broad spectrum spf 30" . Is it any difference between other product which is "spf 30+ pa+++ uva/uvb" ?
Hello Dr Dray. This is the most in-depth series a medical person has ever done on RUclips for sunscreens! You got me converted to physical sunscreens. However there was an article that I came across that when you nanosize zinc oxide it loses its potential to protect against UVA while retaining its UVB protection while micro sizing does not do that. Is there any truth in that. And would also like your thoughts on layering chemical sunscreens on physical ones and vice versa. Regards from India.
Question, after I apply my sunscreen and then make-up, how often do I have to reapply during the day, if I am a teacher? I am mostly indoors with about 30 for recess and then 15-20 minutes at the end of the day at dismissal. Then there the 1 hour drive to school in the morning and afternoon. TIA
Dr. Dray, my eyes are super sensitive to sunscreen. Why product do you recommend for around my eyes that won't sting? I appreciate your help! I've invested so much in sunscreen over the years in trying to figure this one out.
Check out my dark under eye video...description box has good sunscreen recs for this area (stick with zinc/titanium dioxide, fragrance free)
How about in winter time ? How often should we reapply physical sunscreen, considering no sweat or smudges !
So helpful. Learned a lot. Thank you so much.
Thanks!
Hi dr Dray. Thanks for the video, helpful as always. A note about Heliocare supplements. On the instructions in fact they explicitly say that this is not a substitute for the sunscreen but is to be used in addition to it (so people don't think it is a sunscreen in a pill). They also claim to reduce the possibility to get an irritation from heat (like little blemishes on skin). I really like their Tolerance Mineral fluid sunscreen and have used supplements together with it while on holidays. Whether supplements did something difficult to say as I am already diligent about sun protection but my dermatologist said I could try.
I am aware of that, however, there is often a misconception, regardless, that these are "sunscreen."
love your short hair!!
What Spf would you recommend for albino patients? Should they use higher Spfs or 30, 50?
Fantastic videos! am I meant to apply sunscreen to my face before or after a regular face creme?
Hi Dr. Dray, I love your videos! I was wondering if spf in spray was useful at all, could you tell us your opinions on the Lumasol's Post-Makeup SPF 50 Mist, is the one Kim Kardashian promoted on her social media.
Hi Dr. Dray, would you tell us a little about glutathione in IV form please? it just came up in my mind cause i heard it can brighten up skin tone?
Oh how I wish I would have stumbled upon these videos sooner. Everyone always preaches "even one bad sunburn increases your risk of skin cancer", so I just tried to avoid bad, blistering, peeling burns and only get mild sunburns and tan. It wasn't until I started watching your videos that I learned that sunburn isn't necessary for damage to occur, UVA rays penetrate windows, and all the years I spent getting a "healthy" tan were really just years of killing my skin. Now I have dark, ugly sunspots on my lip and wrinkles on my face...and probably some cancer waiting to make it's grand appearance down the road.
I'm just praying that my skin will try to repair itself. Thanks for the sunscreen lessons! I now have 7 bottles of sunscreen scattered about my home, work places, and purse so I'm never without it :)
no such thing as a safe tan
Hi! Thanks for all your info. Great to have a dermatologist's perspective and one who you can confirm facts from the Internet with! I've read differing info on nano zinc oxide sunscreens -are they harmful or not if using on full body? Even if it's not right away, but how about over time? Thanks
they are not harmful, no
I just found your channel and I am loving your videos! I have only watched like 5 so far but I intend on watching them all! I love learning about skincare! I know you do Q&As so I have a question, not sure if you have mentioned this in another video but do you have any recommendations on ingredients to look for for red skin on your face? not like rashy or bumpy redness, more of like a flushed look or turns red to the touch. I was recommended a product that is quite expensive that doesn't seem to be working so I'm hoping to try something else.
Thanks! Check out my rosacea Q&A, as it may be helpful to you.
of course I found this video HELPFUL
Excellent video! Thanks for the info on sunscreen ingredients that react with each other!
My family (most fair skin, me no tan, just burn) went on vaca and I had packed such a "mambo/combo" it was funny to everyone! Thanks to you. (I've never thought of buying the stick sunscreen, but it worked great for hair parts, ears & bald heads!) I came at them with sunscreen, hats, towels, coolibar game strong! , No one got sun burned. They all groaned when they saw me coming with the sunscreen to reapply, or get them before they left (20 minutes) haha
Even the little ones knew to present themselves to reapply! Hopefully they will have less sun damage to their skin than my generation!
Thanks for everything!
Vicki
This is great information, thank you! What is your opinion on adding a Zinc Oxide Powder to a moisturizer?
thanks! that is not a reliable sunscreen
i got very sick when i did this, i threw it away
Hi... i was wondering if u could do a review on the Heliocare 360 fluid cream sunscreen in SPF50 It has an ingredient in it called Fernblock?
Question: With the information that titanium dioxide accelerated the degradation of avobenzone, why did you use chemical sunscreen ( with avobenzone) with physical sunscreen that has titanium dioxide in it?
Hi Dr. Dray, I wanted to ask you your opinion on the SkinMedica
Total Defense + Repair SPF 50+ . It's supposed to also protect against infrared rays, but it's not just a physical sunscreen and a bit pricey. It " sounds" really good though. Thanks
It is a combination sunscreen with iron oxide...so some protection into visible light...but not really offering much other than what is in other tinted sunscreens. It does have niacinamide which can help with redness and impart a skin brightening effect...but as far as sun/uv/ir protection...not anything other than the usual tinted sunscreen
Good Morning Dr. Dray. Thank you for sharing all this information. I have never really worried about protecting my skin but a skin cancer diagnoses in my immediate family has made me take notice. I have learned so much from your vidoes on sunscreen but I do still have a couple of questions. I use the Cerave line of products for cleansing, moisturizing and sun proctection. I find my skin tolerates them well so I am not going to mess with a good thing, I was wondering how close I should get the moisturizer and SP to my eyes. I know my under eye area needs to be protected but getting to close produces watery eyes for hours. Every product I've used seems to produce the same results. My other question is about dark spots and a Dr's appointment. I want to treat my dark spots for future cancer prevention and am not sure what to ask about. I will have to pay out of pocket for what use so I don't want to waste my money trying to find the right treatment. I am not sure I will actually go to a dermatologist (depends on my family practice recommendation at a military facility with limited resources so it may not happen) I want to go armed with good info so I can have a intelligent conversation about my needs. Thanks so much for all you put out there and have a wonderful day!!!
Thanks for sharing!! If the dark spots under the eyes are cosmetic, then the provider can reassure you that they are not of concern. However, cosmetic skin concerns are not covered by insurance. I tolerate both cerave sunscreens (combination one as well as zinc only one) on my eyes.
What do u recommend for people who wear makeup all day and who work in an office most of the day and are only outside when driving/ walking into buildings or to the car ? What do you think about using spray on sunscreens for reapplying over makeup? Because you can't put a lotion sunscreen over foundation. How often do you need to reapply if you are not outside ??
Thank you for the sunscreen series!
One question I have is what sunscreen is good for working in hot indoor environments where you're sweating a lot. I tried a physical sunscreen and it feels like it just runs off.

Wonderful and educational video! I currently use the La Roche Posay fluide XL 50+ chemical sunscreen which I get in Europe when I'm there for work. It has Avonenzone, Mexoryl, Tinosorb S, and other chemical filters. I find it to be very effective. Still, I sometimes apply mineral sunscreen on top to "bounce off" the rays before they even hit my skin. I'm really curious if the studies regarding Avobenzone and Titanium Dioxide took into account when Avobenzone is stabilized by other sunscreen ingredients in a high quality formulation, and when the Titanium Dioxide is silicone coated (which apparently makes it less reactive and produces less ROS). Hmmmm...
Brent Chernoff avonezone still is susceptible to degrading upon exposure to uv...regardless of the mexiryl
I learned something new today. Don’t mix avabenzone and titanium dioxide
Can we layer mineral and chemical sunscreens? Do we apply the mineral or the chemical first? Do we reapply both, one of them or it doesn't matter? Thanks
Love your videos. There are a few sunscreens I'd like to get your feedback on as time / resources permit: MAKE P:REM Capsule Sun Gel, AmorePacific Resort Collection Sun Protection Mist, and Charmzone Albatross Powder Sun. Also, what are your thoughts on the sunscreen facial powders? Thanks in advance.
Another informative video! I use the Obagi hybrid 50 spf, containing zinc oxide 10.5 % and octinoxate 7.5 %. Because of my crazy schedule in the morning, I am not always able to wait 20 minutes before leaving the house after applying the sunscreen. Does the zinc oxide in the formulation offer me some protection immediately? Thanks so much Doctor.
Thanks! I believe so
Dr Dray Thank you!
Which physical sunscreens are beneficial in skin of colour and in which products can they be found, Dr Dray? Caucasian skin is different to skin of colour. Please advise and make videos for us too 🙏
ur videos r soo helpful .thanku
Dr.Dray, I recently heard someone referring to “blue light” and possible skin damage from computers. I’d like to see you discuss blue light if it is truly a concern. Thanks!
i discuss blue light frequently in terms of its contribution to persistent hyperpigmentation
Really?! Where have I been. Just an example of why you probably need to repeat things over and over. Eventually I absorb all the information you discuss 🙃
Do you have any videos on the European/Asian filters like uvinol and tinosorb ??
Altruist, which you have recommended, contáins both avebenzone and titanium dioxide. Is that ok?
How do I reapply my sunscreen if I’m wearing makeup?
is it okay to use a sunscreen containing avabenzone and layer with another sunscreen containing ZINC oxide?
This series has been immensely helpful! Thank you! I am now however slightly freaking out that my perfect SPF routine that I has taken me a long time to find and finally become compliant with every single day is not as good as I thought.... I layer a tinted physical BB cream (zinc and titanium) over my cetaphil oil control spf 30 (chemical including avobenzone) my super oily acne prone skin prefers chemical spf but I know it’s not good enough on its own so I add the tinted physical on top. Other than switching to a fully physical SPF is there another type of chemical filter that protects from UVA but doesn’t react that way with the physical/mineral spf? 😩
mexoryl
Well, I definitely have not been applying enough sunscreen. I was blown away when you told us about Titanium Dioxide and Avobenzone. I know I have some makeup that contains it.
Yeah it is something that is not common knowledge...I don't even recall being taught this in residency, but it has in fact been demontrated (hence why the FDA does not approve of sunscreens to contain both ingredients)
Dr Dray, so titanium dioxide and avobenzone is a no when mixing sunscreen, but avobenzone and zinc oxide is okay? just wondering, because I use elta md and layer with neutragena later on throughout the day
Thank u hon - I used papaya %25 spf / uva uvb protection - some times pure aid spf 30
:)
Hi dr dray. I would like to ask about sunscreen condition and texture? Is it normal that my sunscreen tends to become thicker and stickier as time pass by? Can we still use it even the expiry date is about 1-2 years later?
Hi Dr. Gray, when you mentioned that sunscreen alone isn't enough, do you mean that we also have to actively engage in measures/behaviors to avoid contact with UV rays, i.e. protective clothing? Or did you mean we need to use other products on the face?
Thanks!

Good Morning Dr Dray, I'm learning so much from your videos, thank you! I'm wondering about alcohol, as an ingredient, in lotions. I see a variety of types and I wonder about that. I've heard that certain types are ok, I have no idea what to think about this or if I should try to avoid this ingredient because it is drying. It seems to be in everthing though. Can you comment at some point about alcohol in skin care please.
Jessica murano thanks! I do...it is fine
i always learn so much ! ok my question is i got the differin moisturizer today and the cleanser,my skin has been so parched an i read on these products for use with differin gel well i dont use the differin gel but i do use retin a so i thought hey maybe this will hydrate my face too..do you think this was a good choice? i noticed you like the moisturizer. ive been using cerave foaming cleanser i think thats what is drying my face out so bad.
I love the differin moisturizer...it is essentially identical to the the neutrogena oil free one i have used...cerave pM has niacinamide and ceramdies, that can give you a little more bang for your moisturizing buck; foam cleansers can be drying..maybe try a creamy-fragrance free cleanser
ok thanks !i did pick up the differin cleanser as well its says balancing cleanser and its creamy with no fragrance thought i would give it a whirl...do you think it will be ok? is it like your neautrogena hydrating cleanser at all?
Hi Dry Dray. You said in this video that if we apply avobenzone sunscreen first, then layer it with titanium dioxide sunscreen would cause the avobenzone to degrade. However, in your morning skin care routine video which was uploaded in May 2017, you layered with Neutrogena sunscreen followed by Elta MD sunscreen. I have checked the ingredients of each product and found that the Neutrogena sunscreen contains avobenzone and Elta MD sunscreen contains Titanium dioxide. May I know if it was a mistake that you made or it is because the % of the active ingredient in one or both products are too small to allow the avobenzone to degrade? Thank you in dance for answering my question.
Hi Dr. Dray! Loved the Sunscreen Series. Have you ever heard of the brand ISDIN? They have many products, but one is a zinc sunscreen (Eryfotona Actinica SPF 50) that contains photolyase enzymes,that help repair existing sun damage, as well as vit. E. (It was featured in June's Real Simple magazine as one of the best. Also videos on You Tube) It sounds great, the only drawback is that it is $50.00 for 3.4 oz. :(
Leslie Maloney lol! I doubt that has any truth.
Thank you for the informative videos:)
I apply sunscreen every morning, then wait about 5 minutes and apply moisturizer and then some light makeup. Is this a good order of layering to avoid wiping the sunscreen off? Should I do anything different?
I work in an office with many windows. Am I getting sun damage through the windows throughout the day? Thanks in advance!
Thanks! No it doesn't matter and yes the sun that comes in through the windows is damaging
Dr Dray thank you!
I was recently diagnosed with lupus and this is my first summer since being diagnosed. I wear sunscreen but was wondering if I'm ok to be outdoors (backyard) in the shade without it. I'm currently on Prednisone for the inflammation and tetrinoin cream for the acne that I got as a side effect of prednisone.
Anayeli Atkins thank you so much for sharing this
Thank you!
My pleasure!!
Hi, I'm a fan of your product reviews (and in general). I'm curious what you think about Neutrogena's Hydro Boost SPF 15 product. It seems to be very similar to the hylauronic acid product sold in jars that you use except advertised as with sun protection. I find it is very refreshing and doesn't irritate like other chemical sunscreens I've used on the face.
Cesar A thanks! I advocate spf 30-50. Haven't tried that product but it might be nice in addiction to a regular sunscreen
Cesar A I like the regular hydro boost, but the spf version is too greasy in my opinion 😞and spf 15 isn't enough
Sasha K. I'll definitely have to try the regular hydro boost, but I find that my face completely absorbs the HB product I use especially given that I use a retinoid and BP daily. I learned the hard way that the SPF is not high enough on this product for even minor outdoor exposure/activities the other day, though!
So if the spf number only applies to the UVB protection, how do we know if we have enough coverage for UVA wavelengths? The mineral sunscreen casts don't look great or work well under makeup so I'm still desperately searching for anti-aging UVA sunscreen.
what about sunscreen mists ? like la roche pose
One of my nurses said she worked with a Dermatologist that told their patients that 15spf meant that you should reapply every 15 min and 30spf meant you should reapply every 30 min etc etc. Thank you for explaining spf has nothing to do with re-application time.
thats probably just so you understand it needs to be done regulary, knowing most wont do it that frequent but to be frequent enough
I get that sometimes general statements and "easy to remember rules" need to be made to account for the ignorant general public but I teach doctors for a living and and I get tired of hearing them regurgitate nonsense that they once heard and sticks with them instead of learning the right thing and educating the public properly. It depends on what activity you're doing to calculate how often you should be re-applying ex: swimming, running, sipping lemonade in the shade etc. You should also strive to use minimum 30spf anything more is unnecessary and only possesses a minuscule more amount of protection. @@CrashCarson14
I use physical sunscreen once in the morning before I head out to work. I stay in the office the entire 8hrs, so I don’t sweat. Do I need to reapply sunscreen before I leave work for home?
Huong Bui yes , if you have windows in your office
So long as you're not spending time next to a window, no, you don't.
Doctor does nano or non nano mineral sunblock make a differnce? Is nano ie invisible zinc oxide safe?
Hello dr.! I'm 28 and can i use spf 60 brd spectrum+++... I live in Nepal quite high altitude?
What's with all the in-active ingredients on a label?
So only titanium dioxide degrades avobenzone? I have two powder mineral SPF products. A Supergoop one (all zinc) and a combo product by Derma E which has tit dioxide. So am I fine to use the Supergoop powder on top of a chemical sunscreen?
I heard zinc can degrade avobenzone but you only mention titanium dioxide doing that?
Dr Dray, if you use physical sunscreen, but you don’t sweat or touch your face at all, do you still have to reapply?
Dr Dray, it’s summer beach time! I went today with my family for a few hours. I sat under a umbrella with a big hat and sunglasses. Multiple applications of SPF50 and I still got too much sun. The melasma and dark spots on my cheeks and upper lip are darker. Any suggestions of what else I can do to protect my face? I really don’t care what I look like but while on the beach. Thank you for all your great videos and advice
Dont go to the beach
Hello DR! What you think about the Australian gold tinted sunscreen? It’s good protección for the skin or not!
i found it irritating, but the spf is decent
Which is better for aging? Mineral or chemical?
Dr. Dray, does the active ingredient in Heliocare (fern extract) protect only against sunburn (UVB) or both sunburn and photoaging (UVA & UVB)?
it does not protect against a burn...it mitigates some of the damage of a burn...so you still need sunscreen (in other words...don't allow yourself to burn)
Dr Dray I'm very careful not to burn or tan. Can Heliocare mitigate some of the damage that one gets along with a tan in the way it does with sunburn?
Hi Dr Dray! I am a big fan of your videos, they are a great source of knowledge!!! I am based in Ireland so I don't always "get" the culture related stuff, but I still enjoy watching!
I have two questions:
Question no. 1: Is it OK to use the "beach" sunscreen on a daily basis for face? I found one that is mixed, contains titanium dioxide but also some chemical sunscreens. It is Boots brand Soltan Kids Once Water Play. It is a "baby" sunscreen and can be applied to body and face. So that is question one.
Question no. 2: the sunscreen I mentioned above contains propylene glycol. Is it safe to use in the everyday skincare routine? I read that it has not really been tested on humans and yet it is approved for use in the EU. Are you familiar with any research that shows that it is /is not harmful?
Thank you and have a good day!
1) yes
2.) absolutley safe and a very good ingredient (the internet is full of lies btw)
Thank you very much!!!
Doctor dray can I use Neutrogena sheer zinc body for my face? Because my friend bought me. Please reply my question
No
One more thing....what do you think of the Cetaphil Daily Facial Moisturizer with sunscreen SPF 50+. I am using it with the tinted EltaMD. It is chemical and physical both. I like it a lot, because it works well with my IT CC cream.
Sorry to be so long winded!
if you like it and use it...then it is good!
Oh! Ok. Yes, I use it religiously. I am on my fourth tube, so thank you! Have a great weekend.
Hi Dr Dray.. Is having tocopheryl acetate as part of sunscreen ingredients not good? I've read somewhere that tocopheryl acetate (or tocopherol) may degrade from sun exposure and cause irritation.
it is not a good ingredient as it can, and does, cause irrittation and skin allergies...but sometimes can be hard to avoid in an otherwise decent fragrance free product
Genial. Merci.
