This one's for the girlies (and anyone else who's into skincare) - as an elder, I wish I had committed to using retin-a (tretinoin) sooner. some things I like about tret are:
1 - not having to pay attention to the million new products out there, I have become immune to marketing (I still get to try new moisturizers, HAs, and Vit C serums)
2 - it makes you remember to wear your sunscreen daily, I'd be terrible about that otherwise
3 - no more fine lines (if you don't have any, using will delay you getting them)
4 - you can now order it online from most places without having to spend money on a derm
5 - a tube will last longer than most products from sephora and costs as much/less - more bang for your buck
6 - supposed to be good for acne, I cannot report on that, but others swear by it
i've generally had good skin and get the "you're how old? noooo" but I wish I had committed in my early 30s to build the habit and do more preventative maintenance.
yes the purge/peeling sucks, but once you get on the other side supple babyface glass skin awaits you.
