A couple years ago I was put on a cream that noticeably decreased and practically eradicated the
acne I had. The
cream contained adapelene, however, it was eventually taken off my insurance and became far too expensive. I used this cream in the winter, and as such I never had to worry about the risk of sun exposure with it.
Recently I was told that Differin became over the counter, and worked well for acne. I didn't really know what was in it at the time, but it worked phenomenally!
