I am older, cough, cough, ah hem (40's) and I have used retin-A for years. Currently, I use the cosmetic version called Refissa. It is a bit easier on my skin than regular Retin-A. Even after many years of use, I still cannot use it every day or the area around my mouth gets raw. I use it every other day and even with that if I have skipped too many days, I will tend to get very flaky skin - again, mostly around the mouth. When I apply my Refissa, I use what is called a Blender, made by Obag, in equal parts - it works as a skin lightener - mainly for left over acne spots and freckles. I do moisturize more when my skin flakes but you need to be careful because if you go overboard - at least for me - my skin clogs up and it breaks out. Sort of defeats the purpose.
