The only thing I've found to clear up my adult skin which never cleared from my teenage years has been ProActive. I wish I had tried it when I saw the ad on TV back in the mid 90s. I've done the prescription stuffs. I've done the OTC stuffs (all of them). I've done the health food store stuffs as an adult. Just nothing worked long term, I might get some healing to happen in a few weeks but it never stayed.

FYI - I found that the Salacytic (sorry don't know how to spell it) Acid stuff in most OTC products made my skin worse.
And I found that some of my out breaks in my teen years were Staph Infection which needed antibiotics when I broke out as an adult. I think the alcohol based toners and dermatology prescribed benzo stuff were the only reason why I didn't need antibiotics then.

I didn't get ProActive until I was 30 years old and I finally have clear skin. It's so worth the cost.
