alt Hacker NewsIsn't tanning basically body's reaction to cellular damage? It reduces further damage but that's due to damage done?
(It's largely irrelevant to myself, I pretty much burn immediately and don't / can't really tan, but my wife and her family tan well).

30 years ago I was a lifeguard and got to experiment with this some. I can't tell you the biology specifically, but I have always tanned quickly. The less tan I am, the more easily I burn.
Always been that way for me at least.

The damage gets healed at sleep. Tanning reduces the need to heal.
Yes, tanning is downstream of the activity of the p53 tumor suppressor protein in response to UVB-induced damage: https://www.lesswrong.com/posts/EFiCGc3YwadZBzvZ3/contra-byr...
