What Does SPF Mean?

60 Second Success I see your channel on every video that I watch!

[@memeswiper]

Question: What's better spray-on or creme?

[@nut_4980]

meme_swiper739 YT probably Creme. But is spray-on as good as Creme?

[@Frank.donovan]

meme_swiper739 YT why not both?

[@memeswiper]

Lucky Fireball666 ( ͡° ͜ʖ ͡°)

[@EffieXSteffie]

Cream is better because you're more guaranteed to apply full coverage while with sprays the wind will blow some away and leave you patchy.

[@Borednesss]

Can confirm sprays suck. Just used a bunch this weekend and unless you put the nozzle 1 mm away from your skin and rub it around, you will end up with a patchy sunburn that looks like a rash

[@TheFabrosi]

alright, I'm sure this has been asked, but I went through a lot of comments and didn't see it. is the fact that getting a tan bad? I work outside and I'm constantly in the sun, and I wear SPF 30 all day and reapply after 2 hours. do we know if a "healthy glow" is actually healthy? or does tan always mean damaged skin? also. if you're tanned and wear less than 30 and don't burn, is that more skin damage? no skin damage? maybe a video on dispelling tanning myths would be good!

[@jaclyn4098]

I know this question is really old but yes, a "healthy glow" is still damaging and can still lead to skin cancer and skin aging that doesn't mean you should be afraid to get a tan, but you should be aware that with every tan or burn you're more likely to get skin cancer. You can read some updated statistics in this at www.skincancer.org/skin-cancer-information/skin-cancer-facts It sounds crazy but the only safe way to tan is with self tanners. But those are another story, as not all of those are the best for your skin with fillers and harsh chemicals etc. But good ones do exist.

[@Master_Therion]

"Spf..." Is the sound I make when someone tells me to wear sunscreen. I'm a rebel.

[@MagicAccent]

Rebel with a cancer.

[@Borednesss]

Cancers are rebel body cells, so maybe he is cancer

[@kaimottley9202]

Lol

[@alveolate]

"Spf..." also the sound you make when the deadly lazer fries you in a little heap of ash.

[@Nmethyltransferase]

It's the sound you hear when your girlfriend is a natural redhead.

[@mrnicomedes]

This was a nice episode that hit on all the important points; however, I'd've wished that: 1) it showed UVA/B on a depiction of the electromagnetic spectrum (sorry, physicist here); 2) mentioned some reason why they have different categories (UVA vs UVB: what do they mean; how do they act differently?); and 3) said anything about the mechanisms by which various sunscreens are effective (again, mechanisms, I'm a physicist). What about "physical" vs "chemical" sunscreens? This episode boiled down to, to me, "wear SPF 30+ and reapply often."

[@EliseLogan]

Surprised you didn't mention the difference between chemical sunscreen and physical sunscreen options (mineral sunscreens like zinc oxide or titanium dioxide) - since they work differently,and the science of those differences makes for interesting pros and cons for the two types.

[@TIOLIOfficial]

Someone watched the Ted-Ed video.

[@onerandomnerdygirl2306]

This is super helpful! I'm a Lifeguard and I have very light, sensitive skin. Sunscreen is very important

[@Arwokid]

SERIOUSLY, how much is the "RIGHT AMOUNT"? shouldve done a demonstration or figure (eg 1ml/sqcm) cmon, this is a SCI show, ffs.

[@benparker3224]

I don't understand what all the hate is about, I think Olivia's been doing great.

You got some nice perks!

This video was so helpful!

[@Mralexdenver]

I really need to start using more sunscreen...

[@CrankyPantss]

Good topic, Olivia. Skin cancer is a serious subject. If you're lucky enough to only have the basal cell skin cancer, you only have to deal with the painful and disfiguring cancer removal procedures. Melanoma, though, is a lot more serious and can often be fatal. I've already had several skin cancers cut off of my face and neck and have had a bunch more spots frozen off, as has my father. My friend's dad has had a bunch cut off, including a big chunk cut off from one of his ears. I also have had one friend, a young 25 year old brand new mother die from melanoma. I work in a pathology lab and we get at least a dozen skin cancer biopsies every day. It's fun to sit around and joke about it until they have to start carving chunks of your skin out.

[@G.M.O3]

now people are starting to ask the right questions

[@the_officials38]

Short answer: Just stay Indoors, you'll be protected from deadly rays..... Or will you? _Vsauce Music Starts_

[@Melanie-nd1pt]

Every time you upload a video I swear it was a question in my head the day before that I didn't get to look up 😳 so weird lol love how informative your videos are

[@lizgichora6472]

Thank you!

[@num1shinfan]

love how you snuck in that beach towel product placement

[@CarthagoMike]

At times like these, I am glad that thanks to EU regulations packages down here are quite clear of what something (like sunscreen) is, what it contains and what it is good for.

[@jodinha4225]

Pro tip. Wear clothes. Normally blocks 100% of light on places it covers. Also try staying inside. Guaranteed no sun burn. I hear if you cover the top of the water with oil it will protect everything underneath from sunlight. Curtains are also a good investment. Umbrellas work too Trees help.

[@idunno3302]

Holy wow! No nose ring! XD So much easier to watch!!!!

[@Irixion]

It would be great if sunscreen didn't smell bad, act greasy or get sticky. I just generally limit the amount of time I spend outside

[@smkishtiak]

I came here to learn "Sender Policy Factor". By the way, thanks for the new lesson.

[@heruhcanedean]

I have a serious question since I work in the sun for hours everyday and 89 is the low this week. I wear knock-off underarmor long sleeve undershirt things, those protect better than sunscreen right? I figure a physical layer is better than a cream.

[@mrola8152]

why can I see through glass?

[@aaakitsune]

Got the answer i could not find anywhere else. How long does the protection last for.

[@ozdergekko]

In Europe, they also must protect of UVA, and there is a standardized label for those that have a a UVA SPF of at least 30% that of UFB (letters UVA in a circle).

[@PostColorGear]

I'd be curious what they actually have to add to the sunscreen to make it block the UVA

[@chelseadolly6899]

I just wanna say, Your skin looks so healthy and beautiful!

[@sephimaru2198]

2:40 wait, so you have the UVB protection measured in SPF, but how do you know how much UVA is being blocked?

[@wolfferoni]

What about if you have makeup on though? Do you just put sunscreen on top of makeup? Because that seems like a mess. Or do you remove makeup every two hours to put sunscreen on and reapply? Sounds incredibly time consuming

[@MrMctastics]

This persons really improved in both presentation and content. I guess you could say she has found her niche on this channel. I look forward to seeing these informational videos like this one and the previous one on gas.

[@arthurabraham3271]

Olivia, do a style makeover ! Not exactly a great option to win the crowds over, but still one that will most likely work.

[@shavono8402]

moral of the story: never go outside. mission accomplished.

[@BillyBob_McSanchez]

Tip: If you can't learn it in school, look it up :)

[@magicwaffl3z]

Anyone have any alternatives to sunscreen? Something in typical sunscreen makes me break out in a rash. Not sure what it is in sunscreen that I'm allergic to.

[@CrankyPantss]

Devon Saunders how about physical sun barriers like hats and lightweight longer sleeved shirts?

[@brotendo]

There's a huge difference between oxybenzone/avobenzone sunscreen and sunscreen that uses titanium dioxide or zinc dioxide. I wish you would have covered that.

[@Michael-ke8on]

NIPPLES POKING THROUGH!!! YESSSSSS!!!!!!!!!!!!!!

[@lazyperfectionist1]

And don't forget that protection from sunburn is important _even if you have darker skin._ People with darker skin are _still vulnerable to sunburn._ It just takes a little longer.

[@RosieOs101]

Could you all do one on the clinical trials for sunscreen? I used to work as an R&D chemist for Clorox developing sunscreen detection methods for Burt's Bees (Baby Bee line). It was really interesting, but I didn't learn too much about how they do the trials.

[@benjaminbelay8991]

Does sunscreen stop you from tanning then?

[@chrixthegreat]

That explains why I get burned in about 5 mins while wearing 60spf sunscreen. Downsides of being a ginger. We don't tan and thus, no natural UVA protection.

[@Byter09]

You misspelled Olivias name in the description.. :P Also, yay Olivia! :D

What does "QQs" mean (shown against the question in the starting of the video)?

[@angelchase7857]

so what kind of sunscreen blocks UVA?

[@smackerlacker8708]

None of this has convinced me to slather a stinking, slimy paste all over my skin. I'd rather be dead.

[@Neontronique]

I've had to listen to this article time and time and time and year and year and year again growing up in QLD, Australia. It's a mandatory set of lessons. Americans have no idea what UV is like until they come here.

[@TomsBackyardWorkshop]

Had a family vacation at the beach recently. My mom was paranoid about chemical sunscreen because of some recent news reports so she mad us all use her new organic sunscreen. Everyone got a sunburn. I got second degree sunburns.

[@muskellunge8_123]

I had no idea what SPF actually stood for so I randomly guessed sun protection fact because the words fit in and I was so satisfied when I found out I was right

[@Garentei]

Showed this to my friend but he keeps arguing that he burns "so much less" with SPF 80 and also says more SPF = more protection time.

[@DeepStone-6]

The best SPF is to just not go outside at all like me.

[@cellogirl11rw55]

Can you guys do a video on sunblock allergies?

[@TheReaverOfDarkness]

I'm going to avoid broad spectrum sunscreens from now on because I don't want my protection to interfere with me getting a tan.

[@steverino6954]

What do I use if I want to get a tan?

[@injured_lion]

So you mean people who live in hotter places, their skin get to age faster, That's explain a lot 🙁

[@Williamwahlstrom]

Can you please make a video on why sunscreen is NOT dangerous, i use SPF every day, but in Sweden were i live.. its like a crime to use it. And my family always send me bad report about sunscreen and how its cancerous. There are lots of theories on this... keep up the good work!

[@nbibby]

If sunscreen absorbs and reflects UVB do people wearing it get hotter due to absorption and are they shiny due to reflection if viewed with a UV camera?

[@Naifukiti]

If you're not swimming just wear a long sleeve shirt "NOT" cotton, There are a lot of sun protective clothing that are extremely breathable. With clothing you wouldn't have to worry about reapplying,mess, buying more, ect. Exp. Under Armour HeatGear but there are other bands. Even in summer it's important to wear layers

[@kalashrestha3251]

I think Highest the spf number the more effective it will be. I wear broad spectrum spf 70 during summer time while I go out to shopping. To me spf 15 does not work for me.

[@sarahebert6802]

The title of this video should have been "Wtf is SPF?"

[@googleyoutubename5878]

Or just be a socially anxious nerd like me and wear a hoodie wherever I go because I'm too self conscious to wear just a shirt, and then say its an alternative method to sunscreen. It also helps that there's something in it that irritates my skin and eyes so my parents can stop asking why I don't just use sunscreen.

[@mybackhurts7020]

When I get a tan in Southern California it's browner and when I go up to Central Oregon and get a tan it red why is that?

[@MrMergedWalnut]

Any chance you could explain the balance between the biochemistry of neurotransmitters that trigger pain and the thresholds of tissue damage? For example: I am doing sit ups on a hard surface, it hurts my spine, but is it damaging my spine?

[@jakebuckler5886]

I'm now scared of the sun. I'm gonna hide in a cave forever, there I shall be safe...

[@aharris206]

I hate when people tell me I'm "wasting my money on something useless on anything above SPF 50" I burn extremely bad and my skin is reallllly sensitive. When I use 50 I go pink, 70 is iffy, sometimes I mildly burn sometimes I don't. I need 100 to not burn at all :/

[@Sanngot]

I have the best kind of sun protection. It's called staying away from exposure to the sun.

[@MakeMeThinkAgain]

You should continue with this and talk about UPF and clothing. I don't trust my sunscreen (I sweat a LOT) so I always wear a UPF 50 hat and a long sleeved shirt.

[@cellogirl11rw55]
