I used to use Proactiv when I was in high school and stopped using it when in college.  Now that I am a little older I started suffering from adult acne and decided to go back.  I have very oily skin and suffer from mild acne, but enough to make me seek something to help.  I have been suing the 3 part system for about 6 months now and I am pretty happy with the results.  The one thing that I found out is that I can't miss a day/night usage or else I get a breakout.  Make sure that you wear a white shirt and have white sheets or one's that you don't care about getting bleach smart stains on...
