How To Get Rid Of Acne?

Hello, I am from the UK and for a couple of years now I have had minor problems with acne - but I am a bit of perfectionist and I would like my face to be completely clear. I have been using benoxyl peroxide , zineryt solution and tetralysal (300mg) for a couple of years now and i havn't really noticed any difference . Can you suggest anything that will help make my skin clearer .
