I don't know your age, so I won't go into how your skin may have been in the Pre-HRT days. But I had a lot of years working outdoors in the hot California sun, and winter cold. That along with 61 years of T running trough my system before starting full HRT roughened up the skin a lot, and made it kind of leathery in places. But skin changes were first noticable a few years ago when I was only using a med for my stomach that also worked as a T-blocker. And when I started E it really changed things, even with all the overtanning throughout the years. I hope for bigger improvements this winter.
Advice for you young girls is "USE SUNSCEEN". Unfortunately I don't take my own advice. So I'm still working outside in the sun, and that harsh treatment hasn't helped me along. Yeah, I'm stupid that way, and I'll dumbly go on even after ending up with a skin condition, and a lot of Basil Cell skin cancers. 🙁
