Clindamycin
"I used to have lots of pimples all over my forehead and temples when I was 10 and kinda went on till I was about 12 or 13 that my skin cleared up. Later on a few months after I turned 20 I started to get bumps on my forehead again, not really pimples just bumps (occasionally 1 or 2 pimples) after a few months with this problem I went to my doctor and she prescribed me clindamycin. ITS AMAZING! Just the first night many of my bumps were gone! I'm on my 4th day now and my skin is clearing up pretty good, the only down side is the dryness it leaves you with. With a good moisturizer that problem it's fixed."
