We have a sort of saying/word play in Mexico when you say bye to someone: "Te vas por la sombrita" which translates roughly to "As you leave, walk under the shadow". I guess with the amount of sun this country gets we ought to have fun and excellent sun protection advice ;)

[@chinchillamdgamer]

Fellow Mexican!!! Wooooo.. holaaaa

[@coffeebreak100]

I love this! 🤗

[@HunterDriguez]

For some reason the translation to English has a more solemn tone than it has in Spanish. It sounds kinda cutesy in Spanish with “sombrita” 🤣

[@nitzeart]

@@HunterDriguez Yes I wasn't sure what would be the most accurate translation because English doesn't have the same verb times but well, someone might have a better option!

[@StarKnight70]

we got a similar saying too, but its vai pela sombra, which roughly means the same as your saying, kinda funny how the same saying can appear in different countries :)

“i’m bad at confrontation” “i was pressured to by space nerds” MICHELLE U DONT TELL PPL UR A PUSHOVERRR

[@LabMuffinBeautyScience]

Can't run from the truth 😭😭😭

[@microwavegum]

Iconic

[@Student1483]

The albedo effect, put simply, is light coloured surfaces reflect more sunlight and UV than darker colours. This is why you can get sunburned by snow, and in unfortunate cases, go blind (snow blindness is a real and horrible thing). Make sure you protect your eyes too! Also, water is highly reflective. Wear your sun protection while boating and doing water activities.

[@AllTheArtsy]

Research scientists in Antarctica wear a LOT of sunscreen and wear protective clothing (including full helmets for head and eyes), despite the frigid temperature precisely because they can get burned easily with all that snow and nothing else surrounding them

[@joreads8782]

Actually I did my PhD on this topic and it’s not quite that simple, colour can Be the cause of how things reflect, but it’s not the only factor. UV albedo depends on type of diffuse and direct UV incidence and the material itself. I recommend reading Michelle’s blog and referring to the paper she cites there. Water is also complicated because it doesn’t stay put, but yes it reflects enough to have an effect in some scenarios.

[@miriza2]

Water’s albedo can be high or low depending on the angle of incidence

[@atriyakoller136]

As someone who gets sunburnt very easily and lives in a place where there's a lot of snow, I've never been sunburnt from snow. Mainly because it gets dirty really quick and absorbs UV much better. Still, my chameleo glasses definitely get dark very fast, although the sellers in the optics salon where I got them said they work much better in cold temperatures, so that is a contibuting factor. But I remember one day when I wore them outside, and it was a cloudy day (the sky was completely cloudy, but those weren't super heavy clouds) and they got so dark that they weren't really effective in helping me see in just 15 minutes. So... I'm not a devoted sunscreen wearer (although since I switched to Aha and bha in my skincare, I wear sunscreen in the morning/afternoon/early evening) but that case with my glasses showed me how much UV is really reflected from the snow

[@AmalieLinden]

Extremely late comment, but I can at least say that you're completely right about snow blindness! Specifically in Greenland, you're being told to constantly wear sunglasses if you wish to venture out into the bigger planes of snow. It luckily doesnt happen instantly, so you have a window of time where youre allowed to "forget" putting on sunglasses, with the time depending on things such as where the sun is and how clear the sky is. I once had an art teacher that went to Greenland as a teen/young adult and went against the advice of wearing sunglasses, which luckily for her only caused some temporary blindness and eye pain. ALWAYS wear sunglasses or visors when out in the snow on a sunny day, as it does genuinely strain your eyes a lot and can cause serious damage!

[@rvanderjagt5944]

As somebody who lives in a place that does get the snow, sometimes enough to shut down the highways, the sadly ironic thing is, all the sunscreen and sunglasses get displayed in stores prominently in the summer, and are now starting to go into clearance bins now that beach season is over. There's perfectly good Blue Lizard marked down in some stores right now just because the season changed. On one hand, that's a bargain win for me. On the other, this gives people (myself included before I started watching channels like this,) the idea that you only need sunscreen in summer.

[@psiholog.matei.gabriela]

I have seen spf products sold in winter at the mountains, at ski resorts. I suppose people view spf as a vacation thing and city-sun does not count.

[@globalhikingcr]

@@psiholog.matei.gabriela - With skiing, there is the added disadvantage of altitude. With every 1000 m in altitude, UV levels increase by approximately 10 per cent. I surmise it is the main reason why sunscreen are sold in ski resorts.

[@FlawlessImperfectionBeauty]

@@globalhikingcr I wish I’d known about this as a kid! We used to go in jeans and tank tops for spring skiing when it was above freezing. We’d then slather on aloe to each other’s horrible back burns. We had the added problem of going out with fresh skin that hadn’t seen sun in months, oh the burns!!😂

[@SueRosalie]

UV is even worse in snowy mountains than at the beach but people just don't realise. High altitude is a factor. My daughter got the worse sunburn in her life on a ski trip.

[@jclyntoledo]

​@@FlawlessImperfectionBeautyThat sounds terrible, weren't there any adults around to recommend or give you spf (lotion) to wear?

[@nitzeart]

As a Mexican, this so called "snow" I don't know her either. Apparently is in some mountains too

[@zarinaamor3133]

Sunscreen + hat+ umbrella! I look ridiculous BUT my skin is fab🥳

[@maam8104]

Ok so I'm going to honour Michelle's amazing nerdiness with my own, and let everyone know that Bitumen is a component of Asphalt. Bitumen is the liquid binder that you mix with sand and gravel to make asphalt ☺️

[@joreads8782]

Oh wow I wondered about this, it was always hard to work out what was what when I was trying to research that.

[@dx4055]

Exactly, and there are a lot of types of bitumen 🤓 Ps: did you study Civil Engineering? 🤔

[@fornana]

Just a note from an American: I have never heard the term bitumen, pretty sure people only call it Asphalt. Love the video though!

[@rvanderjagt5944]

I first heard of it in archaeological contexts, and had to look up that it's basically tar.

[@JeanieD]

I’m an American also, and I’m almost 60, and have never heard the term “bitumen” used by anyone in the US (I’v lived in the Northeast , the Pacific Northwest, Florida, and been to almost all 50 states, including Alaska and Hawai’i, as well).

[@alisha1377]

It was sarcasm, I think it went over your head. 🙈😅

[@Kamase318]

Michelle, that was amazing! Was just thinking and wondering about this topic last week as to what items I should buy and wear for total (almost) protection. Have bought over $300.00 in sunscreens and they all...ALL break me out. I decided on a UV-50 hat, dyed my Covid-related masks black or wear a neck gape (Coolibar), bought a sun protection umbrella and I limit my time in the sun. I'm completely comfortable this way after doing all that I can. Thanks so much again. 💕

[@sct4040]

It's the reflection and while you are in the water, the refraction of light that exposes you to UVA/UVB. So, hat, glasses, and mask are great protection, but what about your neck and arms?

[@Kamase318]

@@sct4040 Melasma is my main concern because it is on both cheeks. Sunscreen breaks me out all over my face so I use face masks, neck gapes, protective scarves, my very wide brimmed hats. I also use my protective umbrella (if the UV index is too high) for my face, neck and chest. I'm using all those $300+ sunscreen (with no problems) on my legs and arms in the summertime and use sun protective clothing in the winter. I never worry about exposure on my hands and feet as I like the warmth from the sun there and love my sandals in the spring and summer. I don't demonize the sun and there has to be a good reason why most people feel so much better on a sunny days whether they're inside the house or out. I've got all the protection I want and need. Plus, I'm a person-of-color, so..... Feeling comfortable and covered!😊🤗

[@PassionPno]

We have UPF masks here in Asia that also cover your neck.

[@Liloldliz]

do you have a moment to talk about our lord and saviour, cancer council mattifying moisturiser with spf50+ ??

[@cv7958]

If you have sensitive and/or acne prone skin, I think it's a good idea to trial sunscreens by type so that you may narrow the type of ingredients/SPF filters your skin does not like. It's expensive - as you know - to haphazardly purchase a bunch of sunscreens. There are organic and inorganic sunscreens and even within those categories that are different combinations/concentrations of each ingredients. If I knew I didn't get along with zinc based sunscreens, I would avoid zinc based sunscreens. It's important to narrow the culprit. This can apply to all skincare.

[@silliwtd]

Congratulations on your cometic chemist diploma! If it helps, I took your PhD in chemistry as more than enough of a qualifier to support your expertise in this field. The science speaks for itself!

[@LabMuffinBeautyScience]

Haha thank you! To the best of my knowledge my previous content is still correct, because I always researched everything thoroughly, but it was nice to see everything presented in a systematic way, and I did get a lot of insights into the way things are done which will hopefully be useful for my future content too 😊

[@jordanhu1006]

I’d be super interested to understand how uv damages hair, both colored and non-colored, or chemically treated in other ways, and what ways we can protect it! Hats only protect the top of our heads but not the bottom strands, but there doesn’t seem like a good way that I know of to do that :/

[@toomanymarys7355]

Wear it up.

[@hopefullycosplay]

"Apparently in some countries, there's this thing called snow" - laughs in Denver

[@debayeuxchats5607]

Bitumen is the soft “glue” in asphalt. It’s also the stuff they use to fill in those minor cracks that don’t need a full re-fill. There might be parts of the US that call all asphalt “bitumen” but a lot of the country will call it asphalt and/or blacktop.

[@liznotslow]

It's making me laugh that "old dry snow" reflects less UV than "new dry snow." Like, even the snow can't escape photo aging (or something). 😂

[@liznotslow]

I know it's probably wind/temp changes, or something else causing this difference. Just let me have my joke! 😂

[@xqueenfrostine]

I assumed it’s because it’s dirtier which makes it less reflective? I don’t live in a snowy climate, but my experience with the odd snow storm we get every few years is that snow only looks pristinely white for the first day or so before cars, people and animals track all over it and dirty it up.

[@EspadasYCopas]

I can say that a big hat is better than a cheap sunscreen (no pa ++++, no uva in a circle) against dark spots. I need yo test with a expensive sunscreen. The irony is that i live un Chile, a country with a very thin capa de ozono. Here every sunscreen is expensive and there are almost none mineral alternatives. Others make my skin burn a little.

[@ashleyyyy8833]

I come from a snowy places, and the great thing about snow is that it's usually accompanied by weather that requires covering up nearly everything but your eyes. Snow also causes a glare when it's sunny, so sunglasses are definitely required. In snowy places, the sunnier it is, the colder it is, therefore more sun = more layers and not a lot of exposed skin.

[@sushi_donut]

Standing in this so-called "snow"... XDXDXD

[@lizcademy4809]

Considering I live in a part of the country I call The Frozen North, the closest big city to Frostbite Falls, plus the fact that I have reverse SAD and any temperature over 75°F / 24°C is too stinkin' hot ... yes, I am familiar with that strange white stuff on the ground. :-) Though the sun is low in the winter ... hmm, that makes me think ... what effect does latitude have on sun exposure. How would living in Norway vs. Malaysia change the need for sunscreen?

[@elliez7269]

I laughed a lot 😂😂😂

[@Loostyc]

Such fun

[@rubysresource]

I knew that hats offered limited protection, but I had no idea how limited! Looking forward to the sunglasses video! I better hurry up and order some good ones with side shields before you tell me how bad I'm frying my retinas 🙉!

[@politereminder6284]

Incidentally, I mainly use hats. I live at the equator where the sun is intense. I do notice a difference with each layer. I notice with sunscreen. I notice with hats. I notice with shade seeking. I think it is best to use all, but when I run out of sunscreen (hard to get in my village) I just use a hat.

[@abc_cba]

Nobody can explain concepts like you do ! You're just the best-est ! Best wishes from India 🇮🇳

Hi Michelle, could you please make a video where you are wearing an spf 50 sunscreen both inside and outdoors and after 4-6 hours you measure how protective your sunscreen is. Perhaps if you could show this with a UV lamp in some way that would be fantastic. Sorry I'm just trying to work out if you really need to reapply every 2-3 hours when wearing spf 50 😅

My fav scientist! I do scuba diving. I always wondered how much UV is reflected by water, and how much diffused into the water. Yeah, snow is brutal. Thankfully everything is cold so you can be completely covered :)

[@getyourownshoe]

I love this video, thank you! I carry a parasol all summer, people stare at me but as the sun gets unbearable in California, that staring soon turns to jealousy 😈

[@solveigw]

I love how Michelle uses quotation marks when talking about snow 😂 I bought a hat this summer. I didn't register a significant change in how tanned I got, but I guess this is just one more of these things that work whether we believe it or not 😉

[@debayeuxchats5607]

I wear hats just to protect my hair and scalp. Any day I don’t have to slop on sunscreen in my hair is a day better!

[@CarNumber9]

Thank you for this video! Super informative and I appreciate the little man example. :) This might be a little out of your wheelhouse, but a series on fillers would be really useful. Trying to actually understand the risks is difficult (do they actual dissolve or just migrate? do they stretch out your skin? how do different parts of the face handle fillers? etc.) because so many of the sources one way or the other have vested interest in persuading. Would love an impartial science-based breakdown!

That Swiss cheese diagram is genius! Hadn't seen it before.

[@yensid4294]

My eyes are super light sensitive, bright light blinds me & is a migraine trigger so I have worn sun glasses when outside since a teenager. I now wear oversized, wrap around anti glare sun glasses that can be worn over my prescription corrective glasses when I haven't had a prescription pair of sun glasses made. The glasses need to completely cover the eyes--that includes the sides. I prefer it when they roughly cover my orbital sockets since I don't like putting sunscreen on or around my eyes. If you spend a lot of time outside doing a particular activity or sport (skiing, boating, diving, etc ) they do make athletic clothing & swim wear that has spf ratings now & covers more of your body for water activities where sunscreen would just not hold up.

[@luxuriousv1852]

Thank you for researching and detailing this subject. It’s very informative for people who are sun sensitive or pale skinned. I use both a wide brim visor and a silver lined UPF umbrella for summertime or during any daytime hours with a UV rating above 3. Don’t forget that you still need sunblock too :)

[@ellaraby4397]

Do you have any brands for sun umbrellas ? Struggling with the same thing at the moment!

[@AB-zf8lz]

I was so shocked that this was so interesting. You are truly powerful Michelle.

[@thegreenmanofnorwich]

I loved this one. I'm always up for more nerdery. Did you do a video on protecting hair from UV?

[@tanam7661]

I live in Switzerland so your allusions to snow and Swiss cheese made me laugh. But yes, even with my dark skin tone, we do have to wear sun protection when skiing up in the alps -- most of the time just on the face because ski clothes are generally pretty tick., or bathing in our lakes. I' m not the suntan kind of person but I do like to have picnics with friends outdoors so in Spring, Summer I do wear SPF and hats because as a brown skin girl of Indian origin, I don't want to get darker in summer, especially when swimming. But then again, having been to Australia, I do have the impression that Swiss summers are totally different from your Aussie ones.

[@c.w.8200]

My answer to this is both, I wear sunscreen every day and hats whenever I go outside and I spend a longer time outside, or when it's sunny even when I'm only outside a few minutes. People have looked funny at me and called me crazy but it's become one of my goals in life to protect myself as well as I possibly can from UV exposure. As someone from a skiing obsessed country, most people know that a sunny day on the slope can burn you just like a day on the beach, often worse.

[@chubitochubito5652]

You got your priorities right

[@jclyntoledo]

This is exactly what I'm going to start to do to and ppl already think I'm weird for wearing SPF in the future winter and ob cloudy days.

[@bethdahl3741]

I think it's important to remember that if you live far north or south, the sun won't hang in the middle of the sky but quite low on the horizon. So you'll get alot of direct sunlight on your face and in your eyes (even with wearing a hat) if you're walking towards the sun... on the plus side, the sun only hits your nape and back directly when your're walking away from it.. xD

[@anitamiko9975]

More info on your new cosmetic chemist degree! I feel like this deserves a video of its own. What was the diploma process like? What will you do with it….do share

[@Radjehuty]

This is a really great video and congrats on the degree! Personally, I find hats are mainly to cover the areas of my head that I wouldn't want to put sunscreen on...my scalp. My hair is pretty thin so my scalp will burn and putting sunscreen in my hair would just be disgusting. The brim itself is a bonus.

[@xq39]

I feel like the light can bounce off the ground onto you even if you wear a hat. if youre walking on concrete or some reflective surface in open sun then you need sunblock.

[@LadyAhro]

I’m definitely not ever going to be a sunscreen reapplier away from home so I’ll definitely keep wearing my enormous hats (recently acquired a vast black straw hat popular with the Lady Dimitrescu cosplayers and debating on treating myself to another vast romantic goth hat come next summer.)

I’m in Queensland, and I call the really dark/black road covering bitumen, which after googling I think it is mostly bitumen. But maybe that’s a Queensland thing, heat and floods and all. Great video and congratulations on your degree Michelle 🥳. What do you think about the sun safe school requirements changing, high school students can now wear caps? As someone who got a BCC in front of my ear, an area not effectively covered by a cap, I think it’s a bad move, sigh. My teenager still wears his daggy bucket hat and sunscreen every day.

Bitumen is the binding agent in asphalt! it is a liquid you mix with sand/gravel to make asphal

[@sara_387]

@@maam8104 Yes, I understand that, but I said that bitumen is what I call the dark/black road coating. It does seem in Australia we have bitumen sealed roads, these are constructed differently with bitumen being sprayed, aggregate applied and then more layers to reduce costs by the sound of it, and maybe to allow for easy road repairs. But hell at the end of the day I’m not constructing roads, so I’m just saying that bitumen is what I’ve heard it colloquially called.

[@maam8104]

@@sara_387 haha ok then. I do know how to construct roads but (and this is a big BUT) in northern European conditions and climate plays a big role when building roads. For example, we struggle a lot with roads being destroyed by the ground frost going down a couple of meters. Im sure there are construction methods to deal with the heat etc in Australia which I'm not familiar with. It's really quite exciting how to adapt to different conditions. My point was only to clarify that bitumen and asphalt isn't technologically interchangeable terms ☺️

Fellow qld-er here. Bucket hats never went out of style.

[@LynHannan]

I'm in central Victoria, and my girls are supposed to go to secondary school with caps - their caps have to have the school logo on them. The first couple of years I simply kept "forgetting" to buy them, so they had to use their wide-brimmed hats in the same navy shade of the school colour (no logo). Then I received an email stating they were unacceptable because they were out of uniform. So I bought the caps, dragged out my sewing machine and stitched the caps directly onto the outside of the top of the wide-brimmed hats in as tasteful a way as possible. I sent them each to school like this with notes stating that this was my only compromise and that if they altered these hats in ANY way I would be taking legal action. That they were technically wearing the caps with the logo as per school uniform and I felt this would stand up in court. That their caps were not approved by the Cancer Foundation, so I felt justified in looking after my girls' best interests, seeing as they were not. I got no more complaints in the last 4 years!! My girls are really fair and burn easily, they use sunscreen as well as wide hats, sunglasses and sleeves; they are also proud to wear their true hats to school! My youngest is in yr 10, so only two more years, then I can separate the caps from the hats for the op-shop!

HI Michelle: Question here: I have curly hair. A lot of the information out there says sulfates and silicone should be avoided for curly hair but I haven't noticed that much difference as long as I don't wash too often. Same with the recommended conditioners; does it really mater?

[@sue8412]

The reason they say that is because sulfates can dry your hair and curly hair is by its nature drier. Silicone can form a layer around your hair strand which can: positive - smooth out the outer layer, making it shinier or negative - form a film and prevent moisture from leaving or entering. So for curly hair, it can basically prevent moisture from entering (bad because it’s dry) since the silicones can remain even after you wash your hair, preventing moisture from entering and thus making your hair even drier. So I personally think you can use sulfates and silicones but make sure to use products that work for you, and make sure your shampoo properly cleanses out the silicone (aka contains good surfectants).

Got a diploma because of "pressure". Don't be so humble! You just gotta flex your knowledge!

How do we get vitamin d naturally from sun if we cover our entire body? Should apply sunscreen or cover ourselves with hats and sunscreens in the morning sun before 10am? Thank you for all the information. Love from USA!

[@GeminiDayDreams]

This American learned today that asphalt is also called bitumen... where in America is it called this?

[@katherinemorelle7115]

Yeah, I thought asphalt was the American term. I’m in Queensland and we’ve only ever used bitumen.

[@ImbracaturaHa]

Also american (lived in the middle, and on the east coast) and have never heard bitumen before, only asphalt and “black-top”.

[@peachpink123]

Thank you, very comprehensive and well explained.

every time Michelle said "so-called snow" i giggled because same lmao

[@spark300c]

It depends on skin type and location. I skin type 3 living in north Texas. I rarely ever burn. So wearing a hat is good enough for medium uv. my arms are most damage because I wore board brim hat for years as out door worker. In the mid west which get close to 40 degrees north wearing a hat good enough for type 2. Wearing hat is effective for type 1 in alaska. wearing a hat in southern Australia is not enough because in summer the uv just high as the tropics for long term exposure for type 3.

Great video! I am ready for the sun glasses video

[@notinterested7911]

Omggg, congrats on your diploma!!! I’ll watch the rest of the video now

[@SebastianSeanCrow]

0:00 idk if it protects from sunburns but I use them to keep the sun and heat off of me due to brightness and such

[@susanmcf1]

I love your videos! I walk daily and I get a lot of reflected sun from the side walk, Even though I wear a hat and long sleeves, I must wear a 50 spf sunscreen to help protect me from the reflected sunlight.

[@callie6146]

YAAAAAAAAAASSSS 😍 love me a new Michelle video

[@hiyouseemcool]

I’m surprised how small an amount of uv concrete bounces. I was expecting it to reflect heaps of uv.

[@coor0kun]

I know my hats protect me against sun - the proof is that my favorite hats are heavily sun bleached on the outside and still colorful on the inside 😂
