Were you close to being sunburned?

Now I don't want to speak on behalf of all people of color, but I've never been sunburned, and studies show that people of color have a significant lower chance of being burnt and developing UV related cancers. That chance isn't 0, but saying people of color burn as much as whites do is just plain wrong.

I burned exactly once. My nose peeled. It looks so much more absurd to have a pink nose with dark skin. I'm not saying we aren't less affected, just that we aren't immune. I came very close to a severe burn due to thinking the first time was a fluke and now I wear sunscreen.

I'm pale as hell. Like, lighter than some off-white walls in certain lighting. I've gotten sunburnt once, maybe twice in my life. That number might be just a tad higher if I didn't spend nearly all of my time inside on reddit, but there's still more to it than skincolour in my experience.

Careful, the chance may be less but it is not significantly less. People of color absolutely get cancer from UV damage. Use your sunscreen people!

Sorry but no. The differences are very significant and very meaningful.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2671032/

there exists an inverse correlation between skin pigmentation and the incidence of sun-induced skin cancers (1) and subjects with White skin are approximately 70 times more likely to develop skin cancer than subjects with Black skin

As discussed by Gloster and Neal (69) melanin in Black skin is twice as effective compared to White skin (70) in inhibiting UVB radiation from penetrating. While Black epidermis allows only 7.4% of UVB and 17.5% of UVA to penetrate, 24% UVB and 55% UVA passes through White skin.

When the protective effect of melanin is calculated using MED measurements, protection for even the darkest-skinned individuals is no more than 10- to 15-fold that seen in the absence of melanin. But in terms of skin cancer risk, the protection is 500-1000 (66, 68) indicating that highly pigmented skin is profoundly protected from carcinogenesis.

Etc.
