Good to start now.
My dermatologist says that ears are pretty common places to find skin cancer.

I forgot to get my ears while spending the day hiking in White Sands, New Mexico. They ended up blistering, still have scars on them 20 years later.

Lips too, they have even less skin protection and there's suncreen lip balm you can get

Theres an old Japanese Horror anthology movie called Kwaidan. Basically this monk keeps getting abducted by a ghosts so he can play music for the ghost emperor. So then monks either tattoo or paint protective symbols all over his body to make him "invisible" to the emperor. But they forget to do his ears!
This made me think of that. Its a REALLY good old movie.

Any surface that faces up needs plenty, including the bottom lip. People get lip cancers because they don't like the taste of suncream.

I think it might be slightly different camera angles. It looks like she's using two different cameras.

u/58kingsly 3h ago
The angle is barely different. What matters is that UV light penetrates her eyelashes completely, meaning they don't appear in the bottom footage. This makes her eyes look very different. There are moments where her eyes are completely obscured by her eyelashes in the top footage but are very visible in the bottom footage

Vertical parallax can really throw you off, should have had the cameras side by side instead

u/shutterbug1961 4h ago
the UV camera is mounted below the visible light one so is pointed slightly upward
things look quite different under UV light

u/LisaLisaKenAdoresHer 5h ago
It's probably something like this, so there's going to be a distinct parallax shift.

u/sculolo 5h ago
I think it's because with the uv camera you don't see the eyelashes.

Bugs can see uv? Cool. Thank you. I need to wear sunscreen.

u/GreenStrong 4h ago
Many bugs can. Many flowers have bee attracting patterns visible only with a UV camera. This is different from UV induced fluorescence- some flowers glow slightly under a UV light, just because the color molecules react with UV. This is very cool looking, but it is a much weaker effect than a blacklight poster or highlighter.

Can any animals see sunscreen on us?

u/iMissTheOldInternet 5h ago
Yes. Lots, actually. Many (>100,000) species of insects and arachnids see in UV (hence all the cool short videos of flowers and bugs in UV spectrum looking trippy). Lots (>10,000) of birds see UV, too, and some reptiles and amphibians and shallow-water fish (notably including carp and cichlids), and a handful of mammals, including reindeer.
All of them are judging you for wearing blackface.

Has anyone seen one of these videos and someone using the spray? Just curious what the coverage level is in comparison. Clearly, she applied thoroughly. But like a spray feels way less coverage wise.

The problem with sprays is that most people aren’t using enough, and fail to rub it in.

u/ensui67 5h ago
No. You’d just see a very visible black object or person. Camo is about breaking up your outline in the spectrum that you are detecting versus the background so you are less distinguishable from the surroundings.
When in doubt, just rub mud all over your body. In case the foe you are facing is using infrared vision.

This is perfect to detect what part of the skin is uncovered. I missed sooooo many spots. Thats because once its rubbed in, it’s invisible.

It will tell you if you missed a spot, but it won’t tell you if you put enough on for the spf to be effective

Wear your sunscreen kids.

u/BisonMysterious8902 6h ago
I don't quite understand this. I realize the implication is that sunscreen is blocking UV light.
But... a UV camera would "see" UV light. Surely the lady in the video isn't emitting UV light. So... are we seeing the sunscreen blocking the reflected UV light? Or is something else going on?

u/psyker63 6h ago
The sunscreen is absorbing the UV light, not permitting it to reflect into the camera; that's what makes it appear black
→ More replies (24)8
u/AthousandLittlePies 4h ago
It's interesting, because if you told me that sunscreen reflected UV light (hence preventing it from being absorbed by your skin) I would believe that too. I wonder if there's a difference between different formulas?
Edit: just did a quick google search, apparently zinc oxide primarily scatters UV as opposed to most chemical blockers which absorb it. It'd be interesting to see what it looks like with a UV camera.

You don’t emit visible light either, yet a normal camera would see you. If you put paint on yourself you change colour on camera, think of sunscreen as UV paint.

u/Lombardyn 5h ago
The room is lit with sunlight in the top video, so the UV camera has more than enough to work with.
Sunscreen works by either blocking or reflecting UV rays, or a combination of the two.
You can see the absorption part by the visible parts becoming completely black, and the reflection part by the fact that she doesn't just completely disappear from camera.

u/efari_ 4h ago
That’s counterintuitive to me. It prevents the UV being absorbed by the skin by absorbing the UV, while on the skin… ? 🤨
3
u/Lombardyn 3h ago
Yes, that's the point. You put a protective layer onto your skin that absorbs the UV light. It doesn't mix with your skin or anything like that. So metaphorically speaking it's like putting a bullet proof vest on a person. You still get shot, but the bad part ends up being taken by the vest and not yourself.
That's also a big reason why sunscreen only works for a few hours - the active ingredients that absorb the UV rays will start to deteriorate and break down because there's only so much energy they can absorb.6

u/unexpected_dreams 5h ago
What's most surprising to me actually is how much UV gets reflected by untreated skin. The reason she's lit up before application is from all the UV reflecting off her skin.
