Tretinoin
"Atralin is an amazing ointment for acne prone, sensitive skin. I got a prescription for the topical gel because I was having mild to moderate breakouts and had acne scarring that had occurred before I went on Accutane. My skin is very sensitive, so I needed a mild gel. Every night I put a pea sized amount into my palm, mixed it with a small amount of my facial night cream, dabbed bits of the mixture all over my face and neck and then applied my night cream as usual. At first I was discouraged because I was very consistent with my regime and did not see results for many weeks. Then, after about three months of daily use, my acne and acne scarring began to clear up dramatically. I have not had a blemish in months!"
