Depends. It was too strong for my skin. I started a strict regimen and that helped. I use a gentle face wash like Cetephil, a non alcohol toner by Neutragena, and a light moisturizer without oil. Do this twice a day, everyday.
It depends on the person. I used Acne Free, which I think was just like Proactive, but it worked on me better than it did on my cousin. The Acne Free made my cousin breakout, and cleared my best friends face up. I haven't had much of a problem with pimples though. I used it more to prevent them, then to get rid of them..
