Hello Interloper!

Another good quality study of the effects of Tretinoin confirmed these results, with 79% of people showing an improvement in skin firmness, less wrinkles, and smoother-feeling skin. Some people experienced side effects with dry skin, peeling or redness, but these got better quickly when the cream was stopped.
Retinol is very similar in its effects to Tretinoin, but it is a little less aggressive and doesn’t have to be given by prescription only. If you’re interested in purchasing an effective Retinol product please ask your cosmetic, medical practitioner.
