I think from 10-28 it's mostly genetic, from 28-42 it's both and from 42+ if you look young it's because you took care of yourself.

It's really both.. People look young in my family so I'm pretty happy that I'll probably still look amazing in my 40s or whatever.1

I think its how you take care of yourself not only in counting calories and working out but also in getting adequate sleep and avoiding stressful situations. I know good looking people who became ugly later on cause they were constantly depriving themselves of sleep so that they could further themselves in their career.0
