Largely fitness level and attention to appearance (very-nice well-kept haircuts, probably a little male use of makeup, that kind of thing). Skin care routines (say, consistency of applying sunscreen and wearing hats when outdoors, from early ages on) can vary wildly with local cultural norms and, notably, with class-related socialization, with the result that some cohorts have much nicer skin in middle age than others.

Plus I've been in a few cities where, frankly, it just looks like the gene pool's exceptionally good.

[EDIT] Oh and stuff like serious hair-loss treatments and plugs and such, and skin blemish removal, short of full-on plastic surgery. I can just about guarantee those are more common in rich areas and richer cities than in poorer areas and poorer cities.

That makes sense, I had never even considered regional based attractiveness. Thanks for taking the time to respond.
