Adapalene
"I started using this topical medicine a few weeks ago. Within the first 7-14 days, my skin was a bit dry, and peeled a little bit. This is just the medicine beginning to work, and exfoliating any dead skin cells. However, after about 2-3 weeks, I started to see a huge improvement in my skin. Before using, I had moderate acne, and now I would classify it as light. Make sure you use this medicine at night, and wash it off in the morning. Also, after you put the medicine on your face at night, put a moisturizer on your face (preferably Cetaphil or CeraVe). During the day, do not expose yourself to prolonged sunshine as the affected areas will get red and feel greasy (not a pleasant look and feeling). This is a great medicine, but give it time."
