I have been using proactive for about 5 years now and it works great for me. Everyone is different, everyone has different types of acne. Mine is real temperamental, if I forget to wash my face even one day, my face will break out real bad. But as long as I use proactive everyday, my face stays relativly clear. As of late, I get some break outs. But I think that is because after 5 years of use, my face might be become immune to it...But I am not sure. If you are really concerned about your skin and have tried everything else, it would hurt to try this. I know it's $40 to just try this stuff but I think clearing up acne is worth $40!
Now, I live in oregon and in our local malls, I have noticed that they have proactive solution stands where you can buy all the products there. And if you can find one of those, you can see if they have sample to try. Otherwise, I would highly recommend you buy it from the infomercial. I say this because, once you do, you become a member and get discounts. They automatically send you a new set every 2 months. And every 5th set is free! They send you a catalog with all their other stuff and there are retail prices and club prices. So once you order from them directly, you are a club member and get club prices. But if you go to the store or stand, you pay full retail even if you show proof that you are a club member. Kind of lame!
I hope this helps!
Good luck!
