Well, as expected your post triggers people blabbing about looking (much) younger because...hrt 'works miracles', think of the magically shrinking feet (but no shrinking hands), dropping a few inches in height (but no shorter arms, of course) plus the magic potion for looking up to decades younger.
I think I get what you mean; the eyebags and the extra skin under your chin can make one look older.
PS can do something about this.
But on the other hand: the much spoken about FFS can make even young(er) MTF look years, sometimes even decades older.
Think of the harsh looking cheekimplants, a too short, too narrow nose (some people's noses grow much thinner with age), the augmented lips that make a face look harsh, a too tight facelift, making a face appear gaunt

aging) and last but most certainly not least: the thin, pencilled in or even tattood eyebrows making a face look harsh, cheap, aging, dumb and if arches are too high: longer.
The best is to lose some weight, but not too much. It's a given fact that some bigger, slightly overweight MTF look more fem because of the round curves, facial round curves too.
What's more...a couple of days ago I ran into a MTF who's in her early/mid 40's and post op for decades and the very first thing I noticed was her face....which has masculinised!
I don't know how or what, but I think that's an aging thing.
Born women's faces become more masculine too over the years/decades, but that's a post menopause process that takes at least 15 years.
