I tried klear action and I liked it (klear action is another one claiming to be just like proactiv and you can get it on drugstore.com) when I ran out i picked up the acnefree and hated it. I think the percentages of benzoyl peroxide are different, the toner doesn't have glycolic acid in it and the repair lotion is grainy, so its ok for night, but not durring the daytime. I went back to the klear action (they are the same price) Hope this helps.
I was using Proactive, it gets a little expensive though. It seemed to be working, but I also was wondering about acnefree. I just bought straight BP gel, and I think that I am going to use that instead of Proactive. The BP gel seems to work just as good as anything else and it's so much cheaper!
