I started using retin a seven weeks ago aqo with extremly mild acne, and a friend who is a derm suggested that I take retin a for wrinkles and the mild acne. The acne is now significatly worse and I went to another derm and they prescribed differin and I've been on the differin for one week and I'm not seeing results. What should I expect in the future from this treatment? What will happen if I quit all the treatments? Will my skin go back to the way it was before any treatment?
