Maybe, but I'd be careful about generalizing that kind of thing. Even stuff like consistently applying sunscreen is heavily dependent on class membership, i.e. it's "just what you do, obviously, any time you're going to be outside at all, of course we always have sunscreen on-hand and our kids have been taught to apply it as routinely and consistently as tooth-brushing—wait, why are you asking, doesn't everyone do that?" in some circles, while in other (larger) circles they only break it out for beach or lake days, if at all.
I expect the described behavior is similarly unevenly distributed.
For context, there have been other periods in history when young men were as focused on their apperance as women, used makeup and obsessed about how they were seen.
Social media gives an outlet for this to those who are not wealthy, but none of it is fundamentally new, it was just confined to those who were able to do it.
