Proactiv Proactiv 3 step system Review

When I first started to use Proactiv I was really optimistic that I would get good results.  The first 6 months I saw a lot of improvemetn in my skin and I started to feel like I had found a solution that I could live with for the rest of my life.  After those first six months though I started to break out again, my skin became really dry and very easily irritated.  I was hoping it was just a temporary set back, but for the next two years I went through periods where my skin looked wonderful, these periods usually lasted only a couple of days though, and then I would have weeks where I would break out and my skin would be embarassing.  I tried other acne treatements to see if anything else would work, but nothing worked at all, so I ended up staying with Proactiv because it gave me the best results out of everything else, but it did not cure my acne at all.  The only reason I haven't tried anything else is because I cannot afford to see a dermatologist.
