Benzoyl peroxide / clindamycin
"I've struggled with acne since I was about 13. I've used Proactive, Clean & Clear, Neutrogena, AcneFree, etc. and every other acne system you can think of. 
This product gets rid of my acne in about 4 days; it is all I need now. It doesn't matter what face wash, or toners you use with this, because all you need is the Acanya gel. It's pretty expensive but one bottle (only put on problem spots) lasts me about 4 months.

Acanya has completely has kept my acne away for about a year now. As soon as you put it on, the next morning the size of the bumps reduce in size dramatically. About a week later, I had no acne. I didn't have bad skin, I just needed the right product."
