I am very white, but getting sun feels very healthy for my skin. Obviously I don't want to get burned bad, but good sun exposure helps my skin feel softer and less inflamed. My grandfather also spent most of his days out in the sun gardening, and my mom was just commenting a few months ago about how surprisingly smooth his skin is (and he's 92).
And then another person (of North European ancestry looks) like a brown leatherbag at 50. Anecdotal evidence is sadly not worth a lot.
Many of those smoke or used to smoke, a lot (continues). I live in a country village in south EU and you can see immediately which of the farmers smoke and which don't. Most of them do, but the ones that don't have smooth skin and look younger than they are, the others look like leather bags indeed and older than they are. I guess you can get the same skin without smoking, I just don't see those here.
My sister moved to a southern latitude and pretty much immediately aged 20 years. Never smoked.
Smoking or not smoking, things don't go 'immediately', so probably something else going on there.
