I tried proactive years and years ago, it probably had just come out, and it didn't do shit for me :shrug:

My acne got better after using a combination of soap w/ sylacilic acid to clear the pores and some Derma Klear (no longer made to my knowledge) stuff that was supposed to tackle the bacteria.. I think.

Anyway, that helped real it in, but I still had regular pimples from time to time for years thanks to my oily face and sensitive skin, but over time it's pretty much fixed itself(for the most part). I credit regularly washing my face and anti-bacterial soap. The soap type might not have played any major part, it may have been mostly age and hormones changing, but I prefer using it anyway.
