I use Benza-clin occationally to control my mild acne and it works better tham any other topical medication...BUT, I believe that bad acne can only be treated with Accutane (there are severaly risks associated with Accutane but from personal experience it's the only thing that works) You ever wonder how celebrities all have clear skin? One word...ACCUTANE! They couldn't possibly ALL be born wirh blemish free skin, trust me. Even after Accutane you may have mild acne accationally. I only use benzaclin at night. I swear by these two medications because they worked better than all the others and I've tried several. Beware this stuff will bleach your clothes!
