How do I get rid of my acne???

Im going nuts with this acne nonsense, I've had it for like four years now & I haven't found anything to get rid of it. Everytime I try a new product I get all excited thinking its going to work & then bam, its always a disapointment waiting to happen. I've tried all kinds of neutragina washes, pro active, I even got put on some meds from a derm., Ive used all kinds of different pads, washed it with baby shampoo, all types of other shampoos, Ive used hibiclins, murad.. pretty much like everything. so if someone could give me some tips on how to get rid of it quickly, it would be greatly appreciated :]
