After about 45 yo (except for obese people) men and women start to noticeably lose fat in their face which normally keeps the skin plump and relatively wrinkle-free. Look at the male celebrities whom we have known since their twenties and who are in their 40s today - looks like they 'slimmed down' and have a chiseled look, 'matured and handsomer as he ages' but that look is not so welcomed in a female 'beautiful' archetype.
