Sunscreen sprays seem like the perfect way to reapply sunscreen. But how effective are they? I did some experiments to find out, and the results were pretty shocking.

Honestly I thought her way was the weird way of spraying. It's the influencer way, as it looks good in videos, but I wouldn't say I've ever seen anyone actually doing it in person. I've mostly seen it done they way her husband did it. Keep the spray stationary and more like 10cm away than 20, spray in a very approximate grid pattern, and keep spraying until your face feel wet all over.

@asuka-ryo Месяц назад

@@maimee1 SPF higher than SPF 50 doesn't offer much protection difference (to SPF 50). That's why most brands don't bother to create sunscreens with higher SPFs.

@werm3169 Месяц назад

@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

@fluffycrumpetbaby 5 дней назад

Even on cloudy days, you are exposed to enough of the suns rays that you should definitly be wearing some sort of protection. You can get just as sunburnt in the artic as you can in Australia. Having lived in scotland when i was younger, theres a reason the farmer next door was a constant reddish brown. Most outdoor laborers were tanned, and quite a few older ladies were almost chestnut in colour. Same goes for the north of england. My very Liverpudlian grandmother looked like a conker for most her life from relaxing in sun loungers on her patio. I know it's a joke, but everyone needs sunscreen. (Even snow reflects the suns rays back up into your face)

@fluffycrumpetbaby 5 дней назад

@@Alex-fc8xn I'd ask the question, why are Inuit people not as pale and white as redheads? Since they're either on the same hemisphere location, or higher. Genuinely curious. Possibly because snow is so reflective that living around snow almost 24/7 is quite a lot of UV. But then many live in similar conditions to scotland. Perhaps the red head gene is just a mutiation that wasn't that beneficial, but wasnt detrimental either. Would be intresting to find out.

@baintreachas 4 дня назад

the NHS recommends it, and not (contrary to popular belief) just when abroad or occasionally. Regardless of location, you’re supposed to use it whenever the UV index is 3 or above, and it’s not uncommon for it to get that high certain times of year.

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.

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

@LabMuffinBeautyScience Месяц назад

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.

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.

@MaraMara89 6 часов назад

That's why I am using spray emulsion (no idea if it is called like that in English), I mean the one you spray portion of emulsion and still needs to spread it on your body. I have learn on many mistakes that I am to lazy to use sunscreen in lotion form - it was always too much effort for me and was really sticky for long time. Emulsion is a little more watery, but still easy to apply and for years now I use it with pleasure. Maybe your parents would try? Also: spray is nice if you are alone at the beach and want to apply sunscreen on your back ;)

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.

@LabMuffinBeautyScience Месяц назад

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!

@user-gu9yq5sj7c Месяц назад

I also wondered if paper absorbs the spray more than skin.

@LabMuffinBeautyScience 25 дней назад

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.

@mnilbydntkt Месяц назад

When it comes to discussions about makeup and sunscreen reapplication, our priorities are misplaced. Instead of focusing on finding sunscreens that work with makeup, we should be asking, "How do you reapply makeup over sunscreen?" Choose makeup that's compatible with sun protection, not the other way around. Just like I adjust my hairstyle to fit my sunhat, we need to adapt our routines for proper sun protection. EDIT: To clarify, I do wear both sunscreen and makeup. I've found the best approach is lightweight, cream/liquid formulas applied with clean hands. I wear Hamilton Everyday Face SPF 50+ sunscreen on most days. My sunscreen-friendly makeup routine is Glossier cloud paint for cheeks and eyelids, NYX Jumbo highlighter stick, long-wearing lip liner with QV Face Lip Balm SPF 30+ (reapplied). I also carry cotton swabs for touch-ups on mascara or eyeliner 🩷

@FreshFlamingo Месяц назад

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.

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 🤙

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.

@cristinaferrara6966 Месяц назад

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 27 дней назад

What is the point? Why not just use a cream sunscreen at that point, if you still have to rub it in?

@cristinaferrara6966 27 дней назад

@@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.

@J_Mock92 Месяц назад

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 🤷

@mshmslv 14 дней назад

With the goggles, wouldn't the area around your eyes get absolutely no protection? That's one of the most sensitive areas...

@J_Mock92 14 дней назад

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.

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.

Honestly I don’t know why, but I’m genuinely surprised by the amount of people that actually just spray on their sunscreen? How can you expect good coverage like that? Idk, maybe it’s marketed that way, I’ve never seen an add for sunscreen. I like spray sunscreen because for me it’s less messy to use and easier to measure. I’m not worried about a tube squishing in my bag and I like the feeling of the spray hitting my hands
