Top 7 Sunscreen and SPF Myths | Lab Muffin Beauty Science

[@LabMuffinBeautyScience]

What other sunscreen myths do you see way too often? Or is there something you think might be a myth but you're not quite sure? Let me know!

[@kateginger]

Is it true you have to apply sunscreen every 2 hours?

[@naina7512]

What should the minimum spf rating on lip balms be? Because the highest I've seen is spf 30. If one uses spf 50 on the face and spf 30 on the lips, does that mean reapplication on the lips should be more frequent? Also, does hair need protection from UV rays too? If yes, then how? P.s.: Thanks for this video! It was very informative 😊

[@foodie1707]

@Marie Ooooo that's interesting

[@dyathinkhesaurus]

One sunscreen myth I've heard is that chemical sunscreen absorbs uv radiation on skin, thus overload of "absorbed" free radicals/radiation can likely cause skin cancer or other detriments, so it's better to use "physical" blockers that will scatter. And that one day sunscreen will be proven to be detrimental. I know from watching your vids that physical blockers only reflect about 3% of the rays and absorb the rest. I'm unsure what to make of this data because I've seen that zinc oxide sunscreens turn a light colour under uv light but aren't black like "chemical" sunscreens are. Also, a question I had on your video is on the study showing that sunscreen use doesn't affect vitamin d levels. It mentions that the method was comparing no sunscreen use to spf 17 use. I use spf 50, is the study then not applicable to me? I've also been trying to double apply/diligently use sunscreen after your videos. Also is it best to get vitamin d at 12pm on an extreme uv day for a few minutes or on a uv 3 day for about 15m? Or in the afternoon? I absolutely ABHOR the "sunscreen takes time to absorb myth". I would wait 20m in the toilets at the beach before even thinking about heading out,then never reapplied because I thought if I applied it in the sun it wouldn't work anyway. SO MUCH SKIN DAMAGE 😢 BTW Ive been binge watching your videos this fortnight so much basically this video was like a recap haha!

[@datgreekgal]

Is it true that chemical sunscreens are less potential to trigger malessezia folliculitis than the physical ones?

[@thatsfunny2051]

Favourite myth: "Oh, I don't burn, I tan, so I don't need sunscreen. "

[@erinlikesacornishpasty4703]

This is a mantra I used to say a lot because when I was younger someone actually told me that they thought I had an olive complexion and therefore I wouldn't burn, I would just tan easily. For years, I only wore sunscreen when I was out in direct sun after 6 hours and noticed I was actually starting to get more red. I also wore the wrong shade of foundation on my face for years. About a year ago I got shade matched and was a "fair". I added an SPF to my skincare routine and I was surprised how much it's made a difference.

[@cocuklugumunsesi2874]

i was like this, and i wish someone told me that everybody needs sun protection, it is not about sunburn only

[@brittniep9219]

Julia Bakowski I hear similar things from folks that are dark skinned. My sisters boyfriend is black&latino and is pretty dark. He was happily annoyed when I made him wear tons of sunscreen at Disneyland and explained why. :p

[@deadlifts_steaks.]

Tanning is a sign of skin injury / damage. I wish people knew this.

[@reu2002]

*screams in melanoma*

[@SheraSugar]

My favorite or least favorite myth is that you don't need to apply sunscreen when it's cloudy. The truth is, clouds don't really block all the UVA or UVB rays, so our skin still absorbs UV rays and gets damaged. Most people where I live think that I'm dumb for applying sunscreen when there's no sun lol.

[@deathbeforedecaf7755]

Or you don't need to apply sunscreen in winter. You need to every day if you are outside at all. Many think you don't have to unless you are doing something in the sun for a long period of time like spending the day at the beach or gardening.

[@Poemi10304]

Shera Hamitov I’ve heard UVA goes right through clouds, and that’s the type that gives you wrinkles! 😫

[@MsBlackSequins]

I had a nurse at the derm office tell me this last month...

[@mangoqrwslk92vina]

In Sweden there’s barely any uv in the winter, but I still wear it everyday (except the days I don’t go out)! Of course I put my sunscreen on otherwise. But I think there’s 0 UV in the winter but I’m not sure.

[@nathanjs4207]

Ugh I hate that!!! People look at me like I’m a psychopath when I say I wear sunscreen every day of the year in the Pacific Northwest.

[@Poemi10304]

You forgot to mention that having dark skin doesn’t mean you can’t get skin cancer. I’ve seen comments on other channels, where some people are convinced that they don’t need sunscreen because they’re darker. Btw, thank you for this! It’s sorely needed! You’re my chem nerd hero! 💖 😆

[@BuriedTeeth]

Exactly! Radiation is radiation...maybe its harder to get a painful burn but sunlight is always damaging, to everything.

[@kagitsune]

Yesss, I am so thankful to Jackie Aina for really getting more dark skinned people on the spf train. ☀️

[@lumilabonte3980]

True. I have a black friend who's way dark and had skin cancer.

[@solarmoth4628]

Dark skin means that you are more likely to be diagnosed with skin cancer later and therefore have a worse prognosis. Dark skin people need to be just as vigilant about sunscreen.

[@user-nf3hh8kn5r]

But every sunscreen I've tried makes my skin look metallic or blue. I just gave up a while ago. The ones that don't are out of my price range :(

[@luizacomeron9414]

It' SO GOOD to see someone who's actually studied chemestry on a deep level and brings cientific information about these skincare issues! I'm already a huge fan of your channel!!!

[@JamesWelsh]

Amazing video as always! So, someone left a comment on one of my videos saying that he ‘read a study’ that said we shouldn’t be using chemical sunscreens because they trap heat and raises the body temperature leading to ‘thermal stress’ in our bodies. Is this even remotely true? Did this ‘fact’ get a bit lost in translation?! I’m sure you’ve mentioned before that it raises the body temperature a minuscule amount so not sure what ‘study’ he was referring to 🙃🌞

[@LabMuffinBeautyScience]

I've never seen any study like that! Physical sunscreens produce around 90% of the heat compared to a chemical sunscreen so the difference wouldn't be big either! But I've seen that myth around a lot as well...

[@JamesWelsh]

Lab Muffin Beauty Science thought as much! Thanks for clearing that up ☺️🙏🏼

[@arozeisarozie]

I’ve heard that due to that, a lot of people with rosacea need to steer clear, and honestly, only physical SPF’s don’t wreck havoc on my skin tone. Also, they say the studies aren’t totally conclusive and they can contribute to hormone imbalances? I dunno, I am on the better-safe-than-sorry boat, and sticking to physical.

[@stephaniepower5734]

@@arozeisarozie Dont worry, im on the fragrance and essential oil boat, lol

[@deadlifts_steaks.]

James, the reason is that chemical filters absorbs UV and is converted into thermal energy. So thermal energy can cause hyperpigmentation especially in people with skin of colour. Dr. Vanita Rattan explains this very well.

[@vizk7352]

My biggest pet peeve is when “KZbinrs” just put on foundation with spf and call it a day. 🙄

[@DoctorUltraviolence]

I know!? I see so many YT-ers spread misinfprmation about sunscreen.

[@lheslie5424]

Eso

[@noelleirina5628]

Or even setting spray

[@rosieweaselby]

If you are going to put on as much foundation as some of the beauty gurus, it might actually help a little 😜 (edit: I’m joking but omg they wear so much foundation/concealer)

[@revinaque1342]

A lot of KZbinrs (at least the ones I watch), don't really leave the house during the day. Apart from the occasional meeting, they're usually at home editing or filming, then they go out at night to grab food or buy new products. So it makes sense for them not to prioritize sunscreen. It would be nice if they made sunscreen a part of their makeup routine, though. If only to set a good example for the people watching.

I honestly admire you, all the time and energy you put into research

[@LabMuffinBeautyScience]

Thank you! ❤️

[@houseofschenck6230]

Thank you for explaining the spf levels. I use SPF100 and people constantly tell me I should just use 30 or 50. I burn if I use 30 or 50 but I don't burn when I use 100 so I'll stick to the 100.

[@tinythingy4]

I need to show this to my mom, she believes sunscreen is the reason for skin cancer and not sunshine...

[@Poemi10304]

My experience with my mom is that things don’t have to be true or make sense for her not to believe them. Some people make up their minds to willfully ignore facts. Good luck with that. 😑

[@__R__S__]

My mom does, too. Freaks me out!

[@Poemi10304]

49jubilee If you watch the video, she states the research shows otherwise.

[@tinythingy4]

@Susan Webb she often thinks along the lines of "chemicals" are unnatural and bad and the cause of all sorts of "modern" stuff like allergies, cancer, transsexualism, and whatnot. She really is being nonsensical and believes too much of what she reads on facebook.

[@DellarteDellaGuerra]

My parents don't believe in sunscreen either but showing them this would be no use. Sigh.

[@nickijupiter]

Myth: A THIN layer of sunscreen will protect your skin! I see it time and time again with people showing their morning routines 😖

[@Poemi10304]

Yes! They say, “You only need a little bit. A little goes a long way.” Not with sunscreen! What are you teaching people?! 😱

[@emmakristel532]

I even kept seeing a so called "dermatologist" or something in between those, apply a very thin layer and call it a day

[@mars9399]

I think physical, chemical sunscreen and formulation would result in the need for different amounts

[@user-zm5tt9bq5u]

@@mars9399 Actually it doesn't - you can google for more detailed explanation of SPF protection level validation process, but typically, the SPF is measured by applying 2 mg/cm2 of a sunscreen formula. So it is standardized what amount of product will give the spf promised on the label. This is also where the "teaspoonful for face etc" recommendations are based on. So, if you have two products with spf 20, one thick and one thinner that "goes long way" you are still supposed to use both the same amount (to get same spf).

[@parisz]

You guys around what time do you re-apply for the last time of the day?

[@stephaniepower5734]

So true!!!!

[@houseofschenck6230]

Agreed! This is very straightforward yet full of information.

[@deadlifts_steaks.]

My favourite myth is "dark skinned people don't need sunscreen because we have melanin". Uhm, melanocytes are easily triggered by UV and that is why dark skinned folks are more prone to hyperpigmentation. I can't stress this enough. People think I am crazy because it has been my habit to apply sunscreen every morning.

[@faceonnailsdonehairdid]

Lady, you are out here saving lives (and our skin)! Just discovered your channel from James Welsh's channel (who I also just recently discovered too). I love how you break things down easily for us mere mortals. Glad I could get valuable information from someone who actually understands the science behind skincare and makeup.

[@jasminechen2701]

My favourite " I have been using my DIY sunscreen for years and never got burn, this proves my DIY sunscreen works!" I just want to say, look at your sunspots and fine lines, and you are younger than me.

[@LabMuffinBeautyScience]

Anecdotal evidence should never be considered "proof".

Bro... I’m not a Dermatogist nor an expert. I do know Japan uses some of the most advanced UV filters at there along with many European countries...Please don’t take my word for it look into it!! The USA filters really are the worst, degrading very quickly. I tend to use physical SPF bc I don’t have to worry about filters degrading of course I reapply even before the recommended time. I used Japanese SPF for aesthetics they blend nicely and won’t give me that crazy white cast.

[@cynthiatran4506]

I just went into the Cancer Council’s website a few days ago and they provided the same misleading information about SPF50 being only a little more effective than SPF30. SMH that’s really unfortunate. Thanks for the info Michelle!

[@wap9137]

Cynthia Tran It may be technically true. But from a practical viewpoint most people dont apply the correct amount to get the SPF on the product. So from a practical viewpoint, if you use a 100 SPF and apply 1/2 the correct amount, you can feel confident you are getting 50 SPF.

[@CyrilleLaurent]

Your video deserves billions of view at least. Love it 😍

[@emilyk1597]

Something I'd like to know is are aerosol sunscreens worse than creams? I imagine most of it gets lost in the air (instead of on your skin). Also, I'm kind of worried about the aerosolized spray being inhaled which may or may not cause trauma to lung tissues... Also, wonderful video! Using scientific evidence but making it understandable to a wide audience is never easy to do. Subscribed and liked!

[@annnee6818]

Yeah sprays usually give spotty protection because you lose so much. Derms recommend creams or lotions...

[@nickipelazza8727]

Awesome video! About vitamin D: if you supplement it, make sure your diet is also rich enough in vitamin K since they work in synergy. Too much vitamin D might lead to vascular calcification and some studies suggest vitamin K might prevent that. Ideally you'd get your blood levels tested before taking any supplement, especially for fat soluble vitamins like vit D. Just my 2¢!

[@maha.b1]

Thanks for sharing such a useful info ❤️ will def look into it

[@VainHarmony]

Wow, I didn't know that. I thought vitamin K just helped with absorption. I'll have to revisit my diet. Thanks for sharing!

[@SideEffects297]

What if I take supplements without blood test? Is it bad? Im afraid of having too much vitamine in the body because of side effects, it's my phobia. But I also want to take vitamins. I just buy and take them. They are not deadly right?

[@Panya.V]

True story: I once got a sunburn at night during a full moon. It'd been raining all day long so we stayed inside. That night the weather cleared and it was very hot so we went for a swim in the pool to cool off.

I'd love to hear your take on wearing sunscreen inside the house (if you actually won't leave the house that day). Would the visilble light/blue light be that bad for our skin?

[@__R__S__]

Visible light isn‘t the problem. The problem is that glass doesn’t absorb UVA. So yes, if you want to be protected against UVA at all times you have to wear sunscreen indoors. I do-mainly because I‘m concerned with premature aging and because I use chemical peels and retinol which increase sun sensitivity.

[@Call-me-Al]

What John Snow said. There are UV window filters you can buy to vastly reduce the amount of UV you get indoors, if you want to rely less on the sunscreen.

[@a.j.9098]

John Snow is that your real name or are you a GOT fan? Lol

[@isabelab6851]

I live in SWfL and the sun is so strong year round and it comes through the windows. I have transitions glasses and they turn when the sun is on the window...so yes, it is important to wear it if sitting next to a window

My friend literally said to me to not trust everything on the internet, and like that's true but I don't think reapplying sunscreen every 2-4 hours is wrong since every source says so with a valid reason

[@Tina06019]

There are definitely differences of opinion in the medical profession about how much sun exposure is needed for adequate Vitamin D production. Some doctors and scientist think that no sun exposure is needed. I am not one of them. Although oral Vitamin D supplementation is good (and necessary for most people over 60), I am not convinced that the best course of action is to get no sun exposure at all. However, sunburn is ALWAYS bad. And tanned skin doesn’t absorb as much UV as untanned skin, so a tan, especially a deep tan, is likely to be counterproductive. Vitamin D 25-OH blood levels can be easily checked, and I definitely do this in all patients over 50 (older skin is less able to synthesize Vitamin D, which is in fact a prohormone), and in dark-skinned individuals over 40 who live in temperate latitudes. I advise folks (especially pale people) to use a high SPF on their face, ears, upper chest, back of the neck, the back of the hands, the forearms, and on any exposed scalp. That is in part because removal of skin cancers in these areas is often more disfiguring than in other parts of the body. And everyone should avoid sunburn.

Myth: you need sunscreen all year round, regardless of climate. The amount of youtubers advising you should wear sunscreen in winter who clearly live in California and don't consider that for a lot of places, winter is a time where there's no strength to the sun, and vitamin d deficiency is a potential issue, but wearing sunscreen is just a waste of money and time Edit: check the UV index where you are

[@gzheng7921]

I wish you can have a video dedicated to talk about the ingredients in sunscreen. Im torn because some people say even a tiny amount of some ingredient can cause a lot of harm while you are saying some are harmful because they are fed in large amount to animals. Please make a new video on this!

[@brittniep9219]

Grace Zheng some people or actual scientists with actual studies?

[@gzheng7921]

Brittnie P they claim to have legitimate sources, but its on different ingredients. While its true that i can google scholar articles on controversial ingredients in sunscreen, i wish Michelle can make a video to make our lives easier

[@JDRahim]

I just hope one day there will be sunscreen that need a small amount for a face...not a teaspoon much kinda amount...too heavy, I hate it but I gotta use it.

[@LabMuffinBeautyScience]

I hope so too!

[@bstr-ey6wl]

most concise, brillant demonstration on SPF 50 and 30.

I’m literally obsessed with sunscreen, everyone around me thinks I’m insane. I’m 25 and lather it on first thing after I wash my face and do my skin care, even if I’m just indoors. I keep my curtains closed too!

[@raniatoubia9586]

I watched this video and the one u made a year ago about spf and makeup. I still find it impossible to get a 100% sun protection with a full face of makeup. Foundation WILL slide off of the sunscreen no matter what, and I WILL look like a grease ball, knowing the amount required to get total protection. Specially that I live in a country where it's sunny most of the year. Not applying full makeup everyday before work is a big NO for me.

[@LauraVonDots]

OMG I love this, I just discovered your channel and I'm sharing it with anyone I know, it's so good to have actual facts and quality content. Thank you so much!

[@aarontheabc]

Fantastic video! Going to start linking people to this video! They need to know why I'm so obsessed with Sunscreen! 👍

[@sterlgirlceline]

It would be wonderful if you would review the research showing which specific sunscreen ingredients degrade others. I haven’t been able to find much research on that topic and I see many hybrid sunscreens with both organic and inorganic sunscreen ingredients. I LOVE your channel; absolutely stellar!

[@LabMuffinBeautyScience]

I have some info in the sunscreen sample chapter of my Guide to Basic Skincare! Here: labmuffin.com/skin

[@srajo1807]

I remember when this channel was few thousand views only. this video is great. I haven't considered the UV transmitted . Thanks for discussing Vit. from sun exposure and sun screen. this made me hesitate less to wear sunscreen.

[@paulrodriguez9995]

Omg , you are so dedicated and it’s beautiful to see ! Thanks, im subscribed to you now ❤️

[@Bonafidevixen10032]

If it's worth it, I'm really intrigued about using bicarbonate soda in skin care. I tend to think it's a bad thing cos of the high ph and all that and am shocked that my sister has been using it to exfoliate and cleanse cos it's "natural". A video would be great! :)

[@coceamaria7965]

Very good clip and very good information. More videos like this or with specif sunscreens regarding the protection it will be very usefull.

[@SzekelyEmoke]

I'd like to see a top 5 good coverage tinted sunscreens. I feel like that way I'd get some coverage + protection with 1 task. I'm really interested in a good product like that. :)

[@MissEMc2]

One myth I heard recently is that SPFs will cancel each other out. I had never heard this one before & the person saying it has direct interaction with large cosmetic companies so I had to go research it for myself.

[@MelidelaMoraa]

Hi, which spf ingredients can’t work together? (Or have incompatibilities- Myth 6)

[@wlwcats5810]

I love your videos so much, proper information is so important 😭💘

[@vallerydo]

This is the educational channel that I need. Thank you so much for this!

[@georgiamorandi5795]

Sarah Williams, Senior health information officer, Cancer Research UK Skin cancer is a growing problem in the UK, particularly among older people. Around 11,500 cases a year are related to too much UV exposure from the sun or sunbeds. However, sunscreen isn't the best method of sun protection, whatever the time of year. And you certainly don't need to use it every day. The strength of the sun's rays varies, and between October and March in the UK the sun isn't strong enough to damage your skin. So sun protection isn't necessary - unless you're going skiing, as UV is stronger at higher altitudes. UVA makes up most of the sunlight that reaches Earth, but UVB causes more sunburn, and is also more important for the body's production of vitamin D. Both UVA and UVB are linked to skin cancer. We all need some sun, but it's important not to overdo it and get sunburnt. When the sun is strong, shade and clothing offer the best protection, while sunscreen helps protect the parts you can't cover - choose one with at least SPF15 (for UVB) and at least four stars (for UVA). fashion.telegraph.co.uk/beauty/news-features/TMG11372901/Should-you-wear-suncream-every-day.html

Best subscription so far this year! Thanks for all the education! ❤️

[@nikahopper2178]

Omg thank you!! Such a great video can’t wait to watch more of your videos.

[@amyrebecca6836]

I’m studying cosmetic science and your videos are very informative, thank you

[@jenm473]

i have a HUGE OCD fear of baking chemicals into my skin so am terrified of sunscreen. I even wear little, if any makeup. i just don't know how to get over this fear. i do try to use some natural essential oils to help with some protection, while still allowing the healing I feel like I need from the sun. I won't say which oils, because i already know I am gonna get a lot of hate. :-( i am not trying to be one of the stubborn ones. I have several autoimmune diseases and developed a huge fear of a LOT of chemicals/ingredients. I want to get over the fear of its healthier, but don't know how. Thankyou for such an informative, fact based video. Many blessings!!

[@brittniep9219]

Jen M “baking chemicals?” I think watch more of her videos! You don’t bake your skin. Otherwise we’d all be dark brown and cracked! :p Your skin produces natural oils to protect your skin, you drink water to replenish your body, you also can add moisture and sun protection from these products. You wash them off at the end of the day.

[@anthrogal19]

I find the makeup SPF so annoying. Why don't companies have to give you the correct SPF corresponding to normal amounts of makeup used? It's crazy to think people would use 1/4 teaspoon of foundation.

[@nataliesolomon2141]

I'd like to see some info on the sunscreen-acne relationship. Some say the sunscreen makes it worse because of 'clogging pores' and that sun light helps clear acne, others says sunscreen helps it heal by protecting from the suns damaging effects. I'm left a little confused, but I wear sunscreen everyday anyway as I have fair skin.

[@teavu6093]

Natalie Solomon The poor clogging factor mainly depends on the overall formulation. If you find a sunscreen that doesn't clog your pores it certainly can help your skin.

[@brittniep9219]

The sun definitely doesn’t clear acne 😂 this is a myth based off of the natural antibacterial affects of the sun on cloths drying outside.

[@rimun5235]

Please do a how to build a skincare routine. I feel like a lot of people have such an extensive routine and I don't know if it's necessary or effective. Can you also do this by age? Should you do things differently in your twenties and thirties?

[@LabMuffinBeautyScience]

It's a big topic! I wrote my eBook about building a routine, you can read more about it here: labmuffin.com/skin

[@brittniep9219]

Vitamin D deficiency has also been linked to MS! It also runs in my family; my grandfather, aunt and dad all had low levels of vitamin D when diagnosed. I’m now on a decently high dose of vitamin D for overall health AND to prevent my genetic predisposition for MS being triggered by low vitamin D (or hopefully any other environmental/lifestyle factors). But overall, it’s been studied and linked as an environmental trigger. Just another interesting reason to take vitamin D :)

[@yitshakmeshulam3434]

We apply physical sunscreens also on our lips and hands. Even if they don't get absorbed through intact skin, it is likely that while eating, some will reach the digestive system. If they contain nano particles that could be a problem.

[@susannagobbo1522]

Amazing video!!! Thank you so much, you solved many of my doubts
