Genuinely thank you matpat. My family on both sides have a history of skin cancer, so I'm definitely in the risk. Doesn't help that I literally live in a tropical sunny climate. I did NOT know about the broad spectrum thing. Knowing about it is theoretically life-saving for some of us!

[@MxLulo]

only in case these are new facts too---cold days don't mean skip the protection, shade is partial risk, whatever's closer to the sun (scalp!!!) is going to get the brunt of it even though that's such a tiny-seeming difference--including if you're on a mountain or something; there's nothing saying you can't apply different methods to different areas (I said above I use clothing except for my face, and before it was a stick for everything but my face too); reflected sun is still sun unfortunately but is easy to forget. I watched the lump form and then heal on family i lived with as a kid and listened quite well about her care instructions thereafter. May you find health.

[@anna.owo.]

I recommend avoiding explore, that doesn't mean don't go out, but maybe go for an afternoon walk instead of anything between 12-5, wear sun hats, wet suit tops or t shirts in the beach etc

[@PyroGam3s]

dude, agreed. I thought it was an spf thing because that's what all the commercials advertise but i've never payed any attention to broad spectrum, not knowing that I should. Sometimes I burn even with sunscreen like I didn't have any at all. And sometimes I don't burn a bit. I could never figure out why, now I am really interested to see if broad spectrum makes a difference.

[@aileenonvenus]

yea the main selling point for the expensive sunscreens isn’t superior sun protection but rather formulation. Most on the market sunscreens leave a white cast on dark skin, break out acne prone skin, can’t be reapplied over makeup, or feels super greasy. Honestly, if a $40 gel sunscreen means you’re more likely to wear sunscreen AT ALL, that’s a net positive for your skin health. As a young person i’m really glad the trend now is fancy Supergoop sunscreen and not tanning beds like before :,)

Please don't take what he did in this experiment as truthful. SPF relates to how much UV-B the sunscreen blocks, NOT the "redness" of your tan. You should always wear a sunscreen with at least 30 SPF (after 30, the difference between how much it blocks is minimal since 30 spf already blocks 97%)

The dermatologists are constantly trying to remind everyone that even coating with full coverage is more important than SPF amount. The squiggles of unburied skin on my back from quick spray VS the mostly unburned with just slight slivers of burn on my husband’s from meticulous row by row spraying done on his showed me the importance of full coverage. Of course my toddler son having a pale face with very tanned arms and legs shows us where we need to apply more XD

[@WaitingForTheSubway]

I’ve had similar wonders! I also often work through the night. I’ve been trying to find out-if I put on sunscreen at 8pm, wear it all night, and then experience the sun the following morning, is my spf still effective??

[@crankpatate3303]

I can't find it no more, but I once saw an image comparison between a rice field worker (outside in the sun most of his life) and a chinese monk (inside a temple most of his life) and the monk looked fairly young for his age while the rice field worker looked like beef jerky. This does make sense in my head, but I can't share the source (can't find anymore) nor could I verify the legitimacy of the claim. By the way: Check your Vitamin D levels. Your body produces this through the skin, when it gets sunlight. If you have low vitamin D you may feel tired and sluggish a lot. Vitamin supplements can help, but despite me using one, I still had low vitamin D levels on my last blood test and got a big shot from the doc to fix it.

I learned from cosplay that body paint makes a nice sunscreen too. I went to an outside cosplay event with my friends and everyone complained about getting sun burnt but I didn't get burned because I had body paint on.

[@Iquey]

Most of those paints have titanium dioxide as the white base pigment to make them opaque or bold before adding any colors/dyes/micas so this could definitely work as long as the paint is opaque!

[@PyroGam3s]

it works because it's opaque, the sun doesn't get through, just like wearing a shirt. Just be careful putting things on your skin, even paint.
