I'm a Proactiv ® user since 2004. I got pretty bad acne a bit after I had turned 25. My problem areas were my cheeks, now the problem area is my left cheek ~ it comes and goes. I can't stand it, but I'm at fault. One cannot rely on only products. There are other things to consider such as a healthy diet (food intake), sleep, and proper hygiene. And let's not forget stress factor!
I wish you luck with getting rid of your acne. It's something a lot of us go through and it isn't a nice thing to experience. You're not alone on this, so please don't stress yourself about it, okay? Visit a dermatologist if you have to. Only he/she can give you proper advice and medication ~ if needed.
