Acne, Oh Acne :(

Well, I been having trouble with acne for about 3 years. Everyday I wake up, I scrub my face like I suppose to, my face is always clean. I don't necessarily have bumps (pimples) but I have blackheads. It seem like they don't want to go away! Now I don't know what else to do, & Proactiv is sure taking it's time to work. What else should I do?
