Well I for one know pretty much first hand it's not too late to start at your age.A customer of mine has been using Retin-a faithfully for 20 years! She's 80 something! You would not BELIEVE her complexion! She has no forehead lines, crows feet etc....we've looked and looked at her, at pictures from the past 20 years, she actually looks pretty much the same. I don't know anyone else who has used this for this long. I used it in my thirties for acne and then stopped because it at first made my breakouts worse. At the time I was always told I looked younger than I was. I wish I had kept using it.
Last summer my dermo gave me a prescrip for the generic(Trentenoin) cause she said it not only helps oily skin but wrinkles. I started using it on my neck only. I had blotchy sun damaged skin there and now it looks so much smoother with no blotchiness.I am going to start using it on my face now. I'm 53. So no...it's NOT too late!
