I decided to give a more serious go at prescription Retin A (Curorolgy) since who cares if my skin gets a little flakey right now. Actually - I started from scratch again in early Feb, pre-pandemic, but am taking the time to go very slowly now - with the added benefit that is costs less if you are not applying every day!
I did every 3 days at .020%, and am just working up to every other. Like I said, slow. I had gotten up to daily last year, but then rushed into the next level of .035% with poor results, so I stopped using out of annoyance. It may have been partly to to cold weather, and dry winter skin.
