One thing is to put your knowledge into work for you, second thing is to be taught whats already up there and how it works, so you can adjust and expand this idea/process/knowledge. If I could teach you how to ignite the fire, you only going to that, but if I will show you how fire is being used for cooking, making tools, in control of environment and more, you suddenly have so many options to choose for your future. In addition all those applications may inspire you be more creative. School teaches you basics, but not teaches you how those basics are applied by current products and services - you have to figure it out on your own - if you have available resources to do so - and not every one has them from the early start.
+Matthew Wilson at least they teach us the important things like Literature and Typing. But forreal, our math and science education sucks. Might as well fit this in. it'd be more useful than the science education I received. Come to think of it, there's more science in this video than I learned in most of high-school.
It's no surprise that littlleeextra rice berry is one of the best-selling sunscreens. I’ve observed noticeable changes in my skin. My previous hyperpigmentation has gradually faded. Remember to use the two-finger rule for both the face and neck. Don’t just paint the sunscreen on. Use it the right way, and it’ll work wonders. Pairing it with the rice berry face serum and moisturizer is also recommended. Over time, it’ll make your face glow and you’ll receive plenty of compliments.
It was surprisingly hard to find mineral-based sunscreens when I went shopping for some. Most of the ones I did find were either really expensive, or for children; and they were all in much smaller bottles than I would've liked. As for sunscreen lip balm, I had absolutely no luck finding a mineral-based one in the stores I went to. I did find some mineral-based sunscreens on Amazon, but unfortunately they wouldn't get here until August…
Bear in mind that physical sunscreens often leave a white cast. If you're like me and you have eczema flare ups in response to chemical sunscreens, physical are a better option.
Depending on where you live, you should also consider wearing a wide-brimmed hat, keeping to the shade, preferring long-sleeved shirts and long trousers. On the beach remember to always refresh your sunscreen when you get out of the water, and if you can - prefer morning or evening, rather than the hours when the sun is at the zenith. High SPF might not be enough to protect your skin.
I picked up a titanium dioxide-based sunblock with SPF 130 weeks ago for our beach trip. I didn't know it was a good choice until I've watched this. I only bought it because of the high SPF, was in a smaller bottle (travel-friendly), cheaper than most brands, and can be applied on the face too.
Nice video, but you talked about how UVB reaches the skin and UVA goes deeper. From that point UVA is never mentioned, it's only about sunscreen blocking UVB ... what about UVA? Seemed a bit odd, or did I miss it?
It’s so cool that some people are talking about sunscreens effect on coral. Since I live in hawaii it is vary easy to see where the tourists are by just looking at the coral. If it is dead or bleached most of the time tourists have been there with the chemical sunscreen. If you go swimming in the ocean always wear mineral sunscreen. It’s the best one for the environment. Also fun fact but all chemicals in sunscreen except for titanium oxide and zinc oxide. Everything else is bad.
I love these videos, but as anyone who knows a bit about inorganic chemistry can tell you, the formulae for ZnO and TiO2 are just plain wrong. There are no valence electron bonds, but rather Coulomb attractive forces acting between the cations and anions.
Tbf, it's not like there's a clear-cut separation between covalent bonds and ionic interactions. There is always a small part of covalent interaction. The difference in electronegativity (according to the Pauling scale) is 2.0 and 1.9 respectively which is indeed considered to be rather ionic. So, strictly seen, with the current accepted definitions, it would be more accurate to represent it as 2O(2-) Ti(4+) and Zn(2+) O(2-). However, it is an exaggeration to state that O=Ti=O and Zn=O are "plain wrong".
What's Their Name Again? Yes, that is what I would agree to. But You have to admit, showing only covalent bonds is wrong, so both of us are correct. Using this cation/anion notation is something I usually employ when explaining this stuff to my classmates. Have a great day!
Also search for PPD results of your sunscreen! It offers information on its UVA protection, for example in the form of a PA score. SPF mostly measures UVB protection only.
It's odd, I tan easily but I turn back really pale even quicker, and I've only gotten one sunburn before, in Europe while on the beach for half the day
I used to burn really easily but I guess my skin changed because now it's nearly impossible for me to get a sunburn. I do get a really nice tan, though.
Which sunscreens people used before 20th century ? Since sunscreens was introduced to the population, is the rate of skin cancer on the rise or on the decline ? Why people, who work outside have lower risk to get cancer then the people who work inside ? How often people with dark skin get cancer in comparison to people with light skin ? Which sunscreen use black people in Africa ? Is vitamin D (which actually is not a vitamin) only important for the bones ? What about it build up the immune system, helps with brain function, fight cancer and many more important things ? etc.
다음에는 SPF지수 15에서 30인 선크림 제품을 고르는 것이 좋다는 것을 배웠습니다. SPS지수가 보호된 피부를 태우는 데 얼만큼의 UVB가 필요한지를 나타낸 것을 알아냈습니다. 또 화학적인 선크림은 산호표백 상태를 유발시킨다는 것을 배우고 선크림도 지식을 갖추면 유용할 수 있다는 것을 배웠습니다. 좋은 영상 감사합니다.
1. that girl doesn't need sunscreen at all. 2. if you did the math you see that the SPF shows you directly how much longer you can be exposed to sunlight when you have sunscreen on compared to not having put sunscreen on. SPF 15: you can be 15 times longer exposed to the sun SPF 30: you can be 30 times longer exposed to the sun and so on... 3. i have heard that not every where the sunscreen is labeld the correct SPF in order to protect the consumer from marketing tricks or something like that (like SPF 50 is the max then). I think Veritasium told me about that. not quite sure though.
I work outside all day and apply spf 50 sunscreen multiple times all throughout the day and I still continue to burn and tan. Sigh. Forever with weird uniform tan lines.
I thought SPF (Skin Protection *Factor* ) referred to the fact that, e.g., SPF 30 provides 30x the skin's (presumably an average melanin containing person of european descent) "normal" protection...?
What sort of effect would UVC have on people if we were exposed to it? Like, say, to people in space? Could people in space use a sort of sunscreen to reduce the damage from radiation exposure?
In space there are other more harmful waves, such as gamma which can split nucleons if I'm not mistaken. I'm not too sure what UV Ray can do to your body but the best guess would be that it breaks down your cells? Or perhaps cause some mutations. But even if there are sunscreens to protect against UVC, the sunscreens would probably be no match again gamma rays. (Unless maybe it is made with lead?) I'm no expert on this though, let's see what other commenters think :)
A physical barrier such as a space suit or the shielding and tint on the windows in spacecraft. Tungsten and gold coated items deflect some minor amounts but places such as the ISS are in a low enough orbit so that the radiation is for the most part deflected by earths magnetosphere, providing a safe environment for the astronauts. A more effecient method for long term flights outside of orbit is being researched such as the possibility of creating a magnetic "shield" and other ideas.
There are new chemical or hybrid filters coming up recently because of the defame oxybenzone is receiving. Your sunscreen might have these newer filters (if you're still using the same😅)
na normally spf means how many times longer it will take to get a sunburn. example 10 minutes for mild sunburn, and with spf 100 1000 minutes for same sunburn
How about 100 SPF?? How much percentage of coverage would that give us? If 50 is around 80% then more that 100%?? Because the company Neutrogena sells 100 SPF now, and also is it safe??
The fact that you guys mentioned the impacts on the environment is why I watch your videos every day. Thank you 🐳
ua-cam.com/video/b9zVfj8Q2pk/v-deo.html
Sunscreen truly won’t impact the environment anywhere near other major issues, and protecting yourself would be more important
This is what they should be teaching in schools.
Yea you know, stuff thats actually useful in everyday life
I know right!
One thing is to put your knowledge into work for you, second thing is to be taught whats already up there and how it works, so you can adjust and expand this idea/process/knowledge.

Nope. SPF-30 is good. SPF-15 is okay but not as good. SPF-50 and higher are fakes.

One TED-Ed Episode like this is so much more worth than a hole day school.
+ProbablyNot Anthony I was gonna say that😂
>"I think you need a another day of school."
>"a another day"
Glory hole day at school?
A majority of you need a day of school.
Or Grammerly.
+Matt Smith I like how this Anthony guy feels that he needs to be a grammar Nazi and fails terribly at it himself.
As a ginger, the best sunscreen for me is a substantial coat of mirror-finish silver paint.
Wait tell me what it is plz. I'm semi ginger so I get sunburn kind easily
@@rodrigocarvalhais6666its a joke 😭, suppose to mean the best spfis the is the repelled the sun with her mirror like skin

Do you swim everyday??
This video should be on everywhere instead of commercials.
beautiful visuals in this video. great artist!
Much appreciated.
This is extremely interesting! I would love a Ted ED video on makeup or skincare as well. ❤️
I use only the best, spf 9000.
+Dustin Boyd (ckit) no, just no.
?
Scrub I use spf9001
+GassyBean spf 9002
Levi Willrich damn son where'd you find that
So as an easily sunburned person, I should choose a zinc or titanium oxide SPF 50 sunscreen. Okay.
nah spf 100
As a fellow easily sunburned person, that seems to be the case.
+Rem SPF 100 is false advertisement and a marketing ploy. 50 is the highest.

I just don't go outside... that's my sun screen
Do u go out now
But they are Rays, doesn't need to be in sunlight, it can enter your home, because daylight is the fuckin sunlight

Was it banana boat or sunplay and had a yellow cap? I think i had that too
spf 130? isnt that a lot?
What's the name of the sunscreen?
@@cypstfu your skin will turn into UV moon lol
They should show this video in schools!
Especially the coral reef part!
This has got to be the best artwork in a Ted Ed video that I’ve ever seen
I've learned more on this channel than I have my entire schooling experience...
I dont expose my skin to the sun because of the cancer risk, being in England its pretty easy to do this!
UV rays pass through clouds.
Thanks dude, didnt know that, luckily when its cloudy its usually cold so I wrap up anyway ;)
Still got to protect your beautiful face.
If only this video came out one day ago, before I was sunburned.
CuberClumsy Lol. No.
CuberClumsy or you got evidence?
Thank you for adressing the environmental factor as well!
This comment means nothing to the infinite expanse of the never ending universe
Even such a Minute Action has its implications. Well done though
actually, you increased entropy in the university through this comment...so it does mean something.
It's ok. I'm still stuck on TED-Ed's last video too 😔
Well if I'm commenting on this comment then it means something it means that I wish to share my opinion on your comment
Hello! does anyone know at what hours there are more uvB rays? i had been told that between 10 am and 2 pm it´s that true?
Nice video, but you talked about how UVB reaches the skin and UVA goes deeper. From that point UVA is never mentioned, it's only about sunscreen blocking UVB ... what about UVA? Seemed a bit odd, or did I miss it?
You have a point there. UVB is responsible for causing sunburns. UVA is responsible for early skin aging and DNA damage that can cause skin cancer.
Zinc oxide and Titanium dioxide leave a white cast on your skin. Not good for those of us with darker complexions.
Some suncreen have yellow and green pigments to avoid that
I love these white lines. It mean summer.
Those physical sunscreens have come a long way, can't even remember last time i had white cast. I use sun bum. Paulas choice is good too
There are actually some good brands that don't. (Although a lot do!) My personal love for face right now is Antihelios by la Roche posay
@@ceebeeelem Yes! PC is brilliant. Elegant formulation too.
Never knew of the carbon and mineral based sunscreen...definitely will have to rethink what sunscreen I purchase next time! Love these TED-Ed videos.
I learned more from this than most weeks at school
This is worth more than an entire day in high school
USEFUL PRESENTATION WITH GOOD SIMPLE ANIMATION
The background music is so relaxing I would like to have it :)
I learned more in this video that in high school freshman to senior

Also fun fact but all chemicals in sunscreen except for titanium oxide and zinc oxide. Everything else is bad.
Can you do a riddle/puzzle video? Anyways this video inform me that choosing the right sunscreen is essential!
This is great but I am allergic to certain sunscreens so this is not going to change which one I use.
i dont like tanning
I really enjoy your videos! They are so creative and educational :)
I love these videos, but as anyone who knows a bit about inorganic chemistry can tell you, the formulae for ZnO and TiO2 are just plain wrong. There are no valence electron bonds, but rather Coulomb attractive forces acting between the cations and anions.
That's Zinc Oxide and Titanium and idk, I forgot about that.
Whoa, really??? How strong is that bond compared to a covalent bond?? I'm an electrical engineer, so use appropriate vocabulary pls.
Tbf, it's not like there's a clear-cut separation between covalent bonds and ionic interactions. There is always a small part of covalent interaction. The difference in electronegativity (according to the Pauling scale) is 2.0 and 1.9 respectively which is indeed considered to be rather ionic.

Also search for PPD results of your sunscreen! It offers information on its UVA protection, for example in the form of a PA score. SPF mostly measures UVB protection only.
Great video! A surfer I know uses Zinc because it works better anyway.
The kind that doesn't give you cancer, but if you're already in the comment section, you probably already have it :(
savage
True
I choose a shirt and hat... No cancer risk and 100 UV protection!
Hello! does anyone know at what hours there are more uvB rays? i had been told that between 10 am and 2 pm it´s that true?
I'm going to be looking for those Zinc oxide and Titanium oxide sunscreens. Thanks! :)
I have both chemical and non chemical but for eco. I will use zinc and titanium one for now.
Little steps does a lot.
this is what they should teach this in school
this video appeal to people for protecting marine life and thus it is worth being broadcasted widely

She won't get a sunburn but she could get her skin prematurely aged or melanoma.
great this video came out right after I got my face sunburned
haha
same.
Or break of a piece of a aloe plant and rub the inside on your burn...
+Alice +ZenFood currently doing both but thanks!
Why don't the higher wavelength UV rays penetrate deeper.
because they are shorter and weaker.
Is putting a sunscreen on body and face should be a different product of sunscreen? Or they can be apply on both?
The animators got the chemical symbol for zinc (Zn) wrong. Which was surprising because normally Ted-Ed videos are spot on with the science.
Thank you so much for sharing this information with us!!!
This just taught me to not go outside
Huh, strange I ned 100 spf. In Oklahoma, the UV index is ususlly up to 11 for a lot of summer.
This is the one I go back to, besides doctors, in getting the best summary for the best choice of sunscreen.
Sorry beauty gurus...
I'm Asian and Is it a must for me to wear sunscreen?
If you have exposed skin, you should consider sunscreen to protect your skin...regardless of your ethnicity.
cool only asking coz when i do wear sunscreen,- after a sunny day my face looks like ive got dirt on my face
This was really helpful actually
does sunscreen slow the vitamin D intake?
What sunscreen should I use of I'm a vampire?
Umbrella
this vid appeal people for protecting marine life so it is worth being broadcasted widely
Very informative and excellent video 👏
I make my own TiO2 at home and it's very effective, although I buy every spring two bottles of SPF 80 to avoid tanning or sunburns
I work outside all day and apply spf 50 sunscreen multiple times all throughout the day and I still continue to burn and tan. Sigh. Forever with weird uniform tan lines.
The narrator's voice sounds very similar to Sarah Green's (the no longer elusive Yeti)!
1:19 I like this guy
I once saw a sunscreen with a SPF of 100+
The background music made me feel like I was playing World of Goo, or Little Inferno.
Good thing I don't use the sunscreen I usually have for swimming in the ocean, I'll have to buy a different one for that.
this was actually useful
Would painting myself with white wall paint give me SPF 1000?
Thx for the pointers
I always wondered this? does sunscreen with SPF 100 completely stop the skin from tanning then?
I'm basically the color of paper. I try not to go outside between 10am and 4pm during the summer, and wear physical sunscreen the rest of the time.
Lmao this is my professooorrrrr BAY AREA REPRESENT! Yes she is making us watch this as a part of our biology assignment.
I love how passive aggressive they are with the mineral vs carbon based. Like anyone could afford or have access to a mineral sunscreen
Love the video! Thanks! Why would someone use a lower SPF then? Just to get a tan? Are there any health benefits to lower SPF in some cases?
what is the difference between sunscreen and sunblock?
Try 3 AM Sundowner Suncreen SPF 50PA+++ | lightweight SPF that protects, shields, and brightens your skin all day long.
Thanks so much for that info! Any ideas on brands? Which brands, if any, are better?
why is environmental protection, implied on producers

Which sunscreen is best?

lol i dont think you know what gamma rays are
I simply don't wear sunscreen if I'm going to swim. It comes off anyway. It's better to use it after swimming, I think.
What's with UVA? PPI should be covered too.
I'm a easily tan person. I never get sunburnt, but I like being pale. My sunscreen is staying inside my house, commenting on UA-cam videos.
I use kojie.san Sunscreen SPF 55, but I found none of the physical and chemical blockers as listed in 4:17.
There are new chemical or hybrid filters coming up recently because of the defame oxybenzone is receiving. Your sunscreen might have these newer filters (if you're still using the same😅)
How about adding Zinc powder with your sunscreen?
I always wondered does sunscreen with SPF 100 completely stop the skin from tanning then?
no
essentially all that means is that it's thick enough to last 100 minutes if you don't go in the water etc.
na normally spf means how many times longer it will take to get a sunburn. example 10 minutes for mild sunburn, and with spf 100 1000 minutes for same sunburn
I feel like Im getting smarter even though i don't understand what they are talking about
How about 100 SPF?? How much percentage of coverage would that give us? If 50 is around 80% then more that 100%?? Because the company Neutrogena sells 100 SPF now, and also is it safe??
