I think it's always known to be a less optimal amount of protection, but maybe we shouldn't use this delivery method until we have SPF 150 labeled or something.
@asuka-ryo Not so. Higher SPF compensates for imperfect application (see: applying half the recommended amount of sunscreen halves the SPF; therefore, higher SPF sunscreens will provide higher SPF when applied poorly) and would compensate for the very imperfect nature of sunscreen sprays, too. The reason why brands don't make sunscreens with SPF higher than 50 is because doing so often requires using higher concentrations of UV filters and/or film formers, which becomes cosmetically inelegant as fuck really fast. There's a lot of effort that has to go into making a high SPF sunscreen that people actually want to use

My favorite use of stick sunscreen is to prevent hair dye from staining my face. I hadn't been using it as sunscreen because I couldn't apply it evenly enough and it was visibly whitish when I used enough. But it was on my counter when I dyed my hair purple for the first time in years so I tried it as a stain block. It turns out to be easy to apply to the face, neck, and ears and effectively prevented hair dyes from staining my skin. (I know petroleum jelly is what people usually use, but it's difficult to apply around the hairline without smearing it into my hair, and hair that touches it gets coated and won't take dye.) I realize the SPF ingredients are irrelevant to hair dye blocking, but the waterproof "dry finish" base was useful.
I always spray it into my hand then rub it in!! My thing about lotion sunscreen is the dragging/tough texture, so I don't mind rubbing the spray stuff in because it's much easier and I feel like I can control where it is going the most! I just hope it gets the full spf on the bottle!!

The best sunscreen is the one you'll use. If it takes wasting 80% of the product to get my parents to wear ANY amount of sunscreen, so be it. Though, I do wish SPF was measured under conditions that even vaguely resemble typical use
Yes and no - there are studies showing that if people think they're a lot more protected than they are, it changes their behaviour i.e. more sun exposure without additional protection. Given how much is lost with sprays, it's not that different from assuming the SPF in your makeup is enough and you don't need a dedicated sunscreen.
The "the best sunscreen" quote is the result of research on liquid sunscreen not spray sunscreen. Tbh based on Michelle's test results, I'd say just wear a larger hat and ditch the spray bottle.
Is there really no way of getting them to use a decent basic suncream? I've always hated sprays for various reasons so am obviously biased but I just don't get what benefits sprays have? Especially when applying to the face, having to close your eyes and avoid breathing in while awkwardly trying to make sure you're still spraying at your face is just so much worse than applying a cream to your face like any other moisturiser.
Another reason why spray sunscreens are appealing: I'm a dark-skinned woman who struggles to find and afford traditional sunscreens that don't make my skin look ashy, using sprays removes that issue
anecdotaly i feel like something like avene spf 50+ than lrp xl sunstick if you use that on your lips because avene is much more greasy so it feels like it build more on itself but hinestly would love some testing of a few spf 50+ lips balms!
This all really explains why I got burned so much as a kid, and have moles popping up so much. I was expected to spray my own sunscreen, without any adult help, for as long as I can remember. I thought that getting burned even with sunscreen was just expected. Thankfully I use lotions and protective clothing now.
Yeah that's how you're supposed to do it but it seems she's basing it off how much people on social media use it and people using it to not ruin any make up. So they wouldn't be rubbing it on with their hands.
@@mysticfox1663 I don't see the point of buying a spray product to spray it on my hands and transfer it to my face. If it needs to be applied by hand, I might as well squeeze or pour it on my hands and avoid getting overspray all over. I can also apply it with my fingertips instead of wasting it on my whole hands. And I don't want overspray all over my clothing! I wouldn't mind it on my hair, ears, and decolletage because they need SPF too. But I don't want it on my clothing. I don't want it leaving oily marks on my clothes that may or may not wash out but certainly look bad while I'm away from home.
@@splendidcolors Honestly I'm just glad to find other people who see all the reasons spray sunscreens are such a ridiculous product, I find them really annoying and have never understood why so many people I know default to buying the spray option
Ten years ago, my kids got bad sunburns while we were on vacation. We were using aresol spray sunscreen. We haven't used sunscreen in that form since that day.
I got so badly burnt my first time on Bondi beach because i was doing top up sunscreen with the spray and it was getting blown away and super patchy application. Lesson learnt.
It’s so refreshing to have someone not trying to really dumb things down when discussing something important like sunscreen. Thank you Michelle. I do appreciate it. Heathens 🫣🤭 May you all please take care and stay safe. Louisa. 👏👏👏❤️❤️❤️🤩🤩🤩
We used bananaboat spray and to apply to the face, we would spray onto our hands and then apply like a lotion onto our face. obviously this gets rid of any benefit of not messing up your makeup, but it felt like it was a good application method.
I've never met someone who hadnt complained about sunscreen reapplication after wearing makeup. I always tell them they have their priorities mixed up. Instead, people should be asking *how do you reapply makeup after reapplying sunscreen". Instead of buying sunscreens that can accommodate your original makeup application, you need to find makeup that is compatible with your sunscreen and other forms of sun protection. I change how I do my hair in summer to accommodate my sun hat. I don't force my hat to fit in my high ponytail and expect it to provide the same coverage.
Right, that’s because the answer is “you can’t” unless your goal is 7 layers of makeup sandwiched between 7 layers of cream sunscreen you reapply every few hours over the makeup. Literally 0 people are doing this. So, a better way still needs to be found.
Michelle, you are a gift to the world. Omar is a pretty good sport too! He looks like one of those bread cats with that paper halo! For real though, you always manage to thread the needle of scientific accuracy (like SERIOUSLY PREVENTING CANCERS!) and not only in a funny or entertaining way, but also (I would argue more importantly than even being funny) in a way that doesn`t exclude or alienate people who *don`t like science* and turn away from what they might find intimidating. I just can`t say enough nice things about everything you`ve done on the internet! Standing ovation!
I think we can all agree that sprays suck, but are still better than _nothing_ I guess... I used to HATE when my Mom would rub sunscreen lotion on me as a kid (not everyday, but anytime we were at the pool or played outside for a while). My brother didn't like it either, but I think he mostly complained about having to reapply more often to prevent burning (he got her super fair skin and would burn up real quick without it, while I tanned easily like our Dad). I'm glad she forced us to suffer through at all though, because I don't think I ever burned as a kid, and my brother very rarely did. I can't handle most sunscreen sprays. I have a couple of aerosol ones, and a couple of pump mist bottles meant for the face, but I don't actually enjoy using them lol. I can't use the aerosol ones without feeling like I can't breathe (even just on my body), unless I'm outside or something, and can't use the face mists without wearing tanning goggles to prevent them from getting too close to my eyes (I don't use tanning beds, but used them for the Red Light Therapy and Spray Tanning Booths at my gym). That's actually a good tip btw.... If you _do_ still choose to use a spray sunscreen for _whatever_ reason, then putting tanning goggles on before spraying will help keep it out of your eyes with minimal disruption to your makeup. It's just annoying as hell, like sprays in general 🤷
Interesting results, I discovered aerosol a year ago and still think it’s the best thing since sliced bread!!! Yes it’s expensive & the can doesn’t last long, but the spf50+ 4 hours water resistant, works just as well , gets into places my fingers would miss, Keeps my hands clean, and is fast, I’ve gotten burnt less since I started using it
I recently saw a hair and scalp sunscreen spray that I was intrigued by, especially as a very pale lady terrified of burning. I wasn't going to buy it for a multitude of reasons (too expensive, don't wash my hair everyday, would probably need help getting my entire scalp covered), but this has definitely added another one to that list! I will just continue to not go outside 🤙
One difference between paper face mask you used to test the spray coverage and an actual human face, is that the paper face mask is flat, where a human face has curvatures which likely will get even less coverage than the date you collected on the face mask.
Yep, it presents more of a rectangular profile to the spray rather than an oval - I didn't talk about this but I did try to contour it a bit more, but it was too variable between different masks and probably was more hassle than it was worth. Any mist floating of during the funnel measurement would also increase the calculated % hitting the mask - so very much the best case scenario!
Absorption isn't relevant for this measurement, because we're only looking at mass - the mass of sunscreen landing on the "face" will be the same whether it stays sitting on the surface or absorbs, because of the law of conservation of mass (unless the absorption is so bad that the spray drips off the skin and you lose mass that way). The paper is only used to see where the spray landed, so it's just important to ensure that the mass retained would be the same for the paper funnels and the paper masks.
I just went sunscreen shopping up to about 2 hours ago and I remember seeing the sunscreen sprays and thinking "what would Michelle think about these?" I remember you saying if you use the spray, you must still rub in it. I checked the ingredients (Malibu SPF50+ for example) and I saw a high concentration of Denatured Alcohol. While I have no problem with some alcohol in my products, alcohol being the first listed ingredient is not negligible. Thanks for all the information, Michelle. You're really helping me sound smart outside.
Just wanna say I absolutely love your book, I recommend it to everyone that asks me about skincare. Thank you for putting so much effort and dedication into educating us. ❤
The results are shocking! I’m now reapplying by gently patting my liquid sunscreen and wearing less foundation or skipping it altogether especially when I know I’ll be outside and need to reapply. Can you also test the efficacy of sun cushions??
Love the tenacity and science! I bought your book science of beauty the day it came out; it sits in my salon blowing the minds of people who are waiting!
I bought your book hehe. One question, that maybe was answered in the video, but don't have the time now. But why wait 24h for the product to dry for sprays? They don't have the same problem as Aerosols that a big percentage of the product is propellant, and when they are tested the propellant is taken out. So the formula is tested as a whole, without drying out anything. That means that the non-volatile part of the Spray could have double or more the concentration of "spf" compared to the mix of them . Normal lotion would also lose weight after drying up, probably even more than half the weight in some cases.
I just got your book as a birthday present from my partner and I am overjoyed 🎉🎉 you just nail making complex topics so easy to access and enjoyable to read ❤❤ I feel like I learn something every video I watch and keep coming back to understand more and more the science behind sunscreeen and skincare
I just got a spray sunscreen and I was looking on your channel because I was wondering if you did any experiments, and lo and behold a few days later you upload this! Thank you so much for your rigorous experiments answering important questions for us
10/10 obsessive in-depth content :D I bought your book as soon as the video finished. Plus, I just love a scientist who gets distracted counting, its very relatable.
I use aerosol body sunscreen. My technique has always been to spray directly into my hand and then apply to my skin. I’ll do a liberal spray to the parts of my back I can’t reach with my hands. I’ve never had a problem (no burns), and I do burn without sunscreen. I haven’t tried the face ones, so thank you for the research you did here. I’ll be skipping them.
@@questionablyelven It's faster to apply (absorbs better). Being able to reach parts of my back by spraying is a huge advantage. It's also faster and easier to do touch ups, and less messy. I don't mind creams/lotions, however, if I can't apply them to parts of my back that are exposed when wearing a tank top or dress, then it's not very practical. I prefer not to have to carry around two types, so sprays win. My favourite is Trader Joe's.
This is fantastic! I bought one a few weeks ago and I tried to use it on a windy day at the beach. Immediately I realized it was a terrible idea and changed to a normal one. Thanks for the science ❤
This explains so much. A couple of years ago I had a job that was partly outside and even though I religiously reapplied my spray sunscreen I noticed new freckles and my sunspots getting worse. Thank you for your efforts!
To be fair, the need to re-apply throughout a regular day is not necessarily the whole face. The spray hit's you, where the sun hits you and where most people are oily and sweaty. So in case of distribution I'm not even that mad. But everything else ^^ I apply sprays occasionally on my forehead, cheeks and nose only, where I might get burnt. However, I own them mostly (aerosols) for my scalp and roots around the forehead. For body SPFs the recommendations are usually to drench the skin until it's soaking wet. Why should it be different for the face? But then nobody would buy it. I don't think they are useless as well, but the more brands releasing a version, the more people might think, this is a serious protectant.
As someone extremely fair, I have been experimenting using sprays as an EXTRA on TOP of my cream/lotion formulas, to "set" them and add extra protection. I've noticed less irritation and pinkness since starting to do this. I hope this is acceptable! It seems to ve working for me so far. I'm fair enough that i can get pink wearing SPF 50 after an hour of minimal activity, luke taking my dog to the park.
I spray onto my palm (close range so it doesn’t go everywhere) and apply all over. Kind of goes against the point of spray but I prefer the feel of spray sunscreen over lotions. I hate feeling sticky and sweaty with sun creams.
I just came here to say, I bought your book, I have audio version and I hope to get the print version too! I became a facialist because of you I love skincare science it’s a fun hands on hobby for me (I’m in the social sciences) 😊 I’m so excited at your growth and to see you enjoying what you do. Congratulations
@@violets-for-roses well, the liquid preparation that is packed in the spray bottle can be preferred by some consumers. I prefer the liquid consistency on the skin exposed by my hair partition, instead if a cream or gel. I don’t think that a spray container is needded for such a solution but I guess it is s convenient way op packaging a liquid for controlled dosing.
Yeah, I think there's still a problem with wind and etc when you're applying. All of the sprays I've ever read the directions for tell you to rub the spray on and to spray on your hand and rub that into your face rather than spraying your face, but that's not really how most people use them.
Thank you for this. I just got the Naked Sunday's spray and I've been going crazy with it and your testing just showed it's doing almost nothing. I will not repurchase thanks to you. I'll continue with my sticks which, thanks to you, I count 5 swipes for each area of my face. Your channel helps MORE THAN YOU KNOW! Please continue the great work ❤❤❤
I use a Japanese SPF spray just to make sure I’m completely protected - I use a proper sunscreen that works as a makeup base first, then SPF powder and finish it off with SPF spray, but for actual touch ups I have this Korean cushion SPF cream - it also doesn’t ruin my makeup (though I use very little makeup, just powder+maybe some blush, no bronzing or anything) but I at least know it works.
You're iconic for this. I'm shook I always felt like the sprays I used weren't giving me great protection, but now I see it was basically giving me no protection at all😂
This heathen appreciates the analysis 😊Science is key!! I use a mixture of things and have some body sprays. This helps me make better decisions moving forward
Looooved this video! So much work went into it! I'm impressed and thankful for your dedication to science. It sounds so bad that I don't see a point in buying sunscreen sprays in the first place. Just gentle reapplication works great. Yes, it might slightly mess up my makeup, but I'm not on a photoshoot every day, and I can always wear long-wearing makeup underneath.
The instructions on one of my body sunscreens were actually NOT to spray it directly on your face, but to spray it on your hand and then rub it on your face! That method might get more product directly on the face and lose less to the ether. (But to spray it on your body in the methods described in this video.)
I was getting really anxious about my spray screen until the end when you mentioned the scalp. Im bald as fuck and have had great experiences with 100spf aerosols. I will start using other products for other parts of my body. Thank you!
Hey Michelle, do you know if the brands two peas organics spf 30 and Whole Foods 365 sunscreen are good or effective? The ingredients are very simple and I don’t see any preservative so idk if it will be able to last and I also don’t know if the spf for both is effective itself. I know that chemical sunscreens aren’t bad but I just don’t like putting things on my face because the feeling of having something on my face already feels weird so having fewer ingredients makes me feel better Also do you know if putting translucent powders and arrow root powders over sunscreen will ruin the spf protection, like mess up the layer of sunscreen or something?

anecdotaly i feel like something like avene spf 50+ than lrp xl sunstick if you use that on your lips because avene is much more greasy so it feels like it build more on itself but hinestly would love some testing of a few spf 50+ lips balms!
yeah! most of them that I can find are like 15 spf. and they don't really have much instructions
This all really explains why I got burned so much as a kid, and have moles popping up so much. I was expected to spray my own sunscreen, without any adult help, for as long as I can remember. I thought that getting burned even with sunscreen was just expected. Thankfully I use lotions and protective clothing now.
I never spray directly on my face. I was taught to spray it in my hands and then rub it on my face.
Mine says to do just that on the label
Yeah that's how you're supposed to do it but it seems she's basing it off how much people on social media use it and people using it to not ruin any make up. So they wouldn't be rubbing it on with their hands.
@@mysticfox1663 I don't see the point of buying a spray product to spray it on my hands and transfer it to my face. If it needs to be applied by hand, I might as well squeeze or pour it on my hands and avoid getting overspray all over. I can also apply it with my fingertips instead of wasting it on my whole hands.
And I don't want overspray all over my clothing! I wouldn't mind it on my hair, ears, and decolletage because they need SPF too. But I don't want it on my clothing. I don't want it leaving oily marks on my clothes that may or may not wash out but certainly look bad while I'm away from home.
@@mysticfox1663You're supposed to spray it on your hands? What's the point, then?
@@splendidcolors Honestly I'm just glad to find other people who see all the reasons spray sunscreens are such a ridiculous product, I find them really annoying and have never understood why so many people I know default to buying the spray option
Your book, is about to arriiiiiiiiivvveeeeeee!!!!!!!!!........ First Book in ECUADOR 🇪🇨 🤗 ❤️
Ahhhh hope you enjoy it!!
Ten years ago, my kids got bad sunburns while we were on vacation. We were using aresol spray sunscreen. We haven't used sunscreen in that form since that day.
I got so badly burnt my first time on Bondi beach because i was doing top up sunscreen with the spray and it was getting blown away and super patchy application. Lesson learnt.
Just ordered your book for the city library in Gothenburg, Sweden! Can't wait!
It’s so refreshing to have someone not trying to really dumb things down when discussing something important like sunscreen. Thank you Michelle. I do appreciate it. Heathens 🫣🤭 May you all please take care and stay safe. Louisa. 👏👏👏❤️❤️❤️🤩🤩🤩
We used bananaboat spray and to apply to the face, we would spray onto our hands and then apply like a lotion onto our face. obviously this gets rid of any benefit of not messing up your makeup, but it felt like it was a good application method.
I think it's the best way!
Michelle 👏🏻 for 👏🏻 nobel 👏🏻 prize 👏🏻 2024
I've never met someone who hadnt complained about sunscreen reapplication after wearing makeup. I always tell them they have their priorities mixed up. Instead, people should be asking *how do you reapply makeup after reapplying sunscreen". Instead of buying sunscreens that can accommodate your original makeup application, you need to find makeup that is compatible with your sunscreen and other forms of sun protection. I change how I do my hair in summer to accommodate my sun hat. I don't force my hat to fit in my high ponytail and expect it to provide the same coverage.
Right, that’s because the answer is “you can’t” unless your goal is 7 layers of makeup sandwiched between 7 layers of cream sunscreen you reapply every few hours over the makeup. Literally 0 people are doing this. So, a better way still needs to be found.
The long lasting sun screens (~10 hours) might be the answer but I don't know how effective they actually are @FreshFlamingo
I love when you discover you are correct because that means we get the Final Fantasy battle victory sound clip and I never tire of that!!
Michelle, you are a gift to the world. Omar is a pretty good sport too! He looks like one of those bread cats with that paper halo! For real though, you always manage to thread the needle of scientific accuracy (like SERIOUSLY PREVENTING CANCERS!) and not only in a funny or entertaining way, but also (I would argue more importantly than even being funny) in a way that doesn`t exclude or alienate people who *don`t like science* and turn away from what they might find intimidating. I just can`t say enough nice things about everything you`ve done on the internet! Standing ovation!
I think we can all agree that sprays suck, but are still better than _nothing_ I guess... I used to HATE when my Mom would rub sunscreen lotion on me as a kid (not everyday, but anytime we were at the pool or played outside for a while). My brother didn't like it either, but I think he mostly complained about having to reapply more often to prevent burning (he got her super fair skin and would burn up real quick without it, while I tanned easily like our Dad). I'm glad she forced us to suffer through at all though, because I don't think I ever burned as a kid, and my brother very rarely did.
I can't handle most sunscreen sprays. I have a couple of aerosol ones, and a couple of pump mist bottles meant for the face, but I don't actually enjoy using them lol. I can't use the aerosol ones without feeling like I can't breathe (even just on my body), unless I'm outside or something, and can't use the face mists without wearing tanning goggles to prevent them from getting too close to my eyes (I don't use tanning beds, but used them for the Red Light Therapy and Spray Tanning Booths at my gym). That's actually a good tip btw.... If you _do_ still choose to use a spray sunscreen for _whatever_ reason, then putting tanning goggles on before spraying will help keep it out of your eyes with minimal disruption to your makeup. It's just annoying as hell, like sprays in general 🤷
I'm in India and FINALLY I'll have The Science of Beauty in my hands this Saturday!!! Cannot wait!!
Interesting results, I discovered aerosol a year ago and still think it’s the best thing since sliced bread!!! Yes it’s expensive & the can doesn’t last long, but the spf50+ 4 hours water resistant, works just as well , gets into places my fingers would miss, Keeps my hands clean, and is fast, I’ve gotten burnt less since I started using it
I recently saw a hair and scalp sunscreen spray that I was intrigued by, especially as a very pale lady terrified of burning. I wasn't going to buy it for a multitude of reasons (too expensive, don't wash my hair everyday, would probably need help getting my entire scalp covered), but this has definitely added another one to that list! I will just continue to not go outside 🤙
or get a hat ^^
Get clothing with UPF 50!
Long flowy linen clothing, sun gloves, and a hat! It also feels cooler than having your skin in the sun. Just no artificial fibres.
14:48 I was today years old when I found out that wind exists. Science is amazing
One difference between paper face mask you used to test the spray coverage and an actual human face, is that the paper face mask is flat, where a human face has curvatures which likely will get even less coverage than the date you collected on the face mask.
Yep, it presents more of a rectangular profile to the spray rather than an oval - I didn't talk about this but I did try to contour it a bit more, but it was too variable between different masks and probably was more hassle than it was worth. Any mist floating of during the funnel measurement would also increase the calculated % hitting the mask - so very much the best case scenario!
I also wondered if paper absorbs the spray more than skin.
Absorption isn't relevant for this measurement, because we're only looking at mass - the mass of sunscreen landing on the "face" will be the same whether it stays sitting on the surface or absorbs, because of the law of conservation of mass (unless the absorption is so bad that the spray drips off the skin and you lose mass that way).
The paper is only used to see where the spray landed, so it's just important to ensure that the mass retained would be the same for the paper funnels and the paper masks.
I just went sunscreen shopping up to about 2 hours ago and I remember seeing the sunscreen sprays and thinking "what would Michelle think about these?" I remember you saying if you use the spray, you must still rub in it. I checked the ingredients (Malibu SPF50+ for example) and I saw a high concentration of Denatured Alcohol. While I have no problem with some alcohol in my products, alcohol being the first listed ingredient is not negligible.
Thanks for all the information, Michelle. You're really helping me sound smart outside.
I love seeing the thought process behind the experiment design
Just wanna say I absolutely love your book, I recommend it to everyone that asks me about skincare. Thank you for putting so much effort and dedication into educating us. ❤
Thank you! That's really lovely to hear 😊
The results are shocking! I’m now reapplying by gently patting my liquid sunscreen and wearing less foundation or skipping it altogether especially when I know I’ll be outside and need to reapply. Can you also test the efficacy of sun cushions??
I appreciate your and your assistants efforts to educate us
This is honestly the best channel ever. Also, that sarcastic Daria-like humor, love it.
Love the tenacity and science! I bought your book science of beauty the day it came out; it sits in my salon blowing the minds of people who are waiting!
I bought your book hehe. One question, that maybe was answered in the video, but don't have the time now. But why wait 24h for the product to dry for sprays? They don't have the same problem as Aerosols that a big percentage of the product is propellant, and when they are tested the propellant is taken out. So the formula is tested as a whole, without drying out anything. That means that the non-volatile part of the Spray could have double or more the concentration of "spf" compared to the mix of them . Normal lotion would also lose weight after drying up, probably even more than half the weight in some cases.
huge respect for all your sacrifices
GIIIIIRL I want more of these tests I loooooooved this!
Much respect for your dedication to this experiment.
the way you mentioned your book (which I already have and am currently enjoying btw)! :D your humor is just the best.
I just got your book as a birthday present from my partner and I am overjoyed 🎉🎉 you just nail making complex topics so easy to access and enjoyable to read ❤❤ I feel like I learn something every video I watch and keep coming back to understand more and more the science behind sunscreeen and skincare
I just got a spray sunscreen and I was looking on your channel because I was wondering if you did any experiments, and lo and behold a few days later you upload this! Thank you so much for your rigorous experiments answering important questions for us
10/10 obsessive in-depth content :D I bought your book as soon as the video finished. Plus, I just love a scientist who gets distracted counting, its very relatable.
I love that you said you lose count all the time. I relate so hard.
I use aerosol body sunscreen. My technique has always been to spray directly into my hand and then apply to my skin. I’ll do a liberal spray to the parts of my back I can’t reach with my hands. I’ve never had a problem (no burns), and I do burn without sunscreen. I haven’t tried the face ones, so thank you for the research you did here. I’ll be skipping them.
What is the point? Why not just use a cream sunscreen at that point, if you still have to rub it in?
@@questionablyelven It's faster to apply (absorbs better). Being able to reach parts of my back by spraying is a huge advantage. It's also faster and easier to do touch ups, and less messy. I don't mind creams/lotions, however, if I can't apply them to parts of my back that are exposed when wearing a tank top or dress, then it's not very practical. I prefer not to have to carry around two types, so sprays win. My favourite is Trader Joe's.
This is fantastic! I bought one a few weeks ago and I tried to use it on a windy day at the beach. Immediately I realized it was a terrible idea and changed to a normal one. Thanks for the science ❤
I just got your book in the mail :) thank you for your work!
Your book has just arrived and it looks so amazing! Thank you for it😊
Another insanely genius video. Michelle! The skin care community would be so incomplete without you!
Was literally just about to order a spray sunscreen today... glad I saw this in my sub feed!
This explains so much. A couple of years ago I had a job that was partly outside and even though I religiously reapplied my spray sunscreen I noticed new freckles and my sunspots getting worse. Thank you for your efforts!
Love your work and am always happy when I see a notification! Thank you :)
Thank you Michelle! ❤ I love you and your super videos 🎉
Your dedication is amazing! I love the thoroughness. 👏
Thank you for all the info shared on your channel!
To be fair, the need to re-apply throughout a regular day is not necessarily the whole face. The spray hit's you, where the sun hits you and where most people are oily and sweaty. So in case of distribution I'm not even that mad. But everything else ^^ I apply sprays occasionally on my forehead, cheeks and nose only, where I might get burnt. However, I own them mostly (aerosols) for my scalp and roots around the forehead.
For body SPFs the recommendations are usually to drench the skin until it's soaking wet. Why should it be different for the face? But then nobody would buy it. I don't think they are useless as well, but the more brands releasing a version, the more people might think, this is a serious protectant.
As someone extremely fair, I have been experimenting using sprays as an EXTRA on TOP of my cream/lotion formulas, to "set" them and add extra protection. I've noticed less irritation and pinkness since starting to do this.
I hope this is acceptable! It seems to ve working for me so far.
I'm fair enough that i can get pink wearing SPF 50 after an hour of minimal activity, luke taking my dog to the park.
I am so impressed with your tenacity!!!
I appreciate all your hard work, your honesty and your personality. Many blessings!!!💖💖💖
I spray onto my palm (close range so it doesn’t go everywhere) and apply all over. Kind of goes against the point of spray but I prefer the feel of spray sunscreen over lotions. I hate feeling sticky and sweaty with sun creams.
Thanks for the deep dive and effort and for thinking about us heathens.
I just came here to say, I bought your book, I have audio version and I hope to get the print version too! I became a facialist because of you I love skincare science it’s a fun hands on hobby for me (I’m in the social sciences) 😊 I’m so excited at your growth and to see you enjoying what you do. Congratulations
The effort you have put in is astounding
The only way to apply spray is to spray it into the hand’s palm and then rubbing it onto the skin
True but that would mean aerosols are a waste and people don't want to hear that.
18:03 she talks about that. It defeats the whole purpose of a spray.
@@raygin6581That's what I thought. 🤔
@@violets-for-roses well, the liquid preparation that is packed in the spray bottle can be preferred by some consumers. I prefer the liquid consistency on the skin exposed by my hair partition, instead if a cream or gel. I don’t think that a spray container is needded for such a solution but I guess it is s convenient way op packaging a liquid for controlled dosing.
Yeah, I think there's still a problem with wind and etc when you're applying. All of the sprays I've ever read the directions for tell you to rub the spray on and to spray on your hand and rub that into your face rather than spraying your face, but that's not really how most people use them.
Thank you for doing this!! We see your effort to get the most precise results!
Thank you for suffering for us and making this brilliant video! I just ordered your new book, can't wait to read it :)
Thank you for this. I just got the Naked Sunday's spray and I've been going crazy with it and your testing just showed it's doing almost nothing. I will not repurchase thanks to you. I'll continue with my sticks which, thanks to you, I count 5 swipes for each area of my face. Your channel helps MORE THAN YOU KNOW! Please continue the great work ❤❤❤
Your dedication to science(and this channel) is mind boggling. Thank you Michelle!!!!
Yay, I was just wondering about this! ❤
I use a Japanese SPF spray just to make sure I’m completely protected - I use a proper sunscreen that works as a makeup base first, then SPF powder and finish it off with SPF spray, but for actual touch ups I have this Korean cushion SPF cream - it also doesn’t ruin my makeup (though I use very little makeup, just powder+maybe some blush, no bronzing or anything) but I at least know it works.
I wouldn’t be surprised if you didn’t get enough protection with the cushion either
I absolutely love your channel and the information you put out. I’ve learned so much! Thank you!
You're iconic for this. I'm shook I always felt like the sprays I used weren't giving me great protection, but now I see it was basically giving me no protection at all😂
This heathen appreciates the analysis 😊Science is key!! I use a mixture of things and have some body sprays. This helps me make better decisions moving forward
Thank you SO MUCH for all your work, you are wonderful!
Your videos never disappoint! Thank you!!!
Looooved this video! So much work went into it! I'm impressed and thankful for your dedication to science. It sounds so bad that I don't see a point in buying sunscreen sprays in the first place. Just gentle reapplication works great. Yes, it might slightly mess up my makeup, but I'm not on a photoshoot every day, and I can always wear long-wearing makeup underneath.
The tests really made me giggle, your lovely assistant sure is a good sport 😂
The instructions on one of my body sunscreens were actually NOT to spray it directly on your face, but to spray it on your hand and then rub it on your face! That method might get more product directly on the face and lose less to the ether. (But to spray it on your body in the methods described in this video.)
Boost! I appreciate all the work and education you do!
the book is great btw!!
you are so thorough!!! thank you so much for putting yourself through this for science!!!
I was getting really anxious about my spray screen until the end when you mentioned the scalp. Im bald as fuck and have had great experiences with 100spf aerosols. I will start using other products for other parts of my body. Thank you!
Michelle for the win once again ❤ I’m glad I waited for a video like this before buying a sunscreen spray, thank you!!
The queen has graced us again with more sunscreen experiments!! 🤩🤩
I'm loving the edit on this video 😂❤
Hey Michelle, do you know if the brands two peas organics spf 30 and Whole Foods 365 sunscreen are good or effective? The ingredients are very simple and I don’t see any preservative so idk if it will be able to last and I also don’t know if the spf for both is effective itself. I know that chemical sunscreens aren’t bad but I just don’t like putting things on my face because the feeling of having something on my face already feels weird so having fewer ingredients makes me feel better
Also do you know if putting translucent powders and arrow root powders over sunscreen will ruin the spf protection, like mess up the layer of sunscreen or something?
Shocking results! Btw, I’ve got your book and it’s been amazing reading it! 📚😊
before i watch i just wanna say i always run to your sunscreen videos theyre so informative and thorough 🩷
Thank you!! This is an amazing video!!
