I guess it shouldn’t be surprising that there’s not one miracle supplement. :)

With skin so pasty that I can’t tan, but also being the first adult in my family to not have skin cancer (at my age), now I’m not sure if I’m doing it “right” or “wrong” by avoiding the sun.

Agreed. Fitness and proper vitamin levels don't require sunburns, skin cancer, or prematurely aged skin to attain. All of the "macho" men who thumb their noses at skin cancer (or smoking and lung cancer) are usually the ones who have their noses removed when a malignancy is discovered.

No one said it did. But it also might not require sunscreen with equal likelihood. /shrug

The point is we don't know, which is the case with most lifestyle/diet choices that aren't obviously bad in a vast majority of cases, like smoking and overeating.
