I have been using proactiv for the last few years. I first started taking it about 5 or so years ago, when it first came out. It seemed to help, but my face would get very irritated and dry from the lotions. I was on it for a year or so, then went off of it for over a year and a half. My acne came back, soon after that and I tried all kinds of stuff. I was going to school, under a lot of stress, eating poorly and not exercising, which all contributed to the problem getting worse. I eventually reordered proactiv, and started using the spf moisturizer, along with the make up (foundation & powder), and it has really helped get the acne under control. I now exercise regularly and eat more fruits and veggies. The acne isn't 100% gone, but it is a far cry from where I was without proactiv. I'm sure the exercising and eating right has helped. Overall, I think it is a good product, and the best that I have used out on the market for acne.
