Does proactive really work?

I want to try it really much so but,my mom thinks it's a bogus product. I want to know if there is anyone who has tried it. Is it worth it? I don't have really bad acne but I want to get my skin completely clear. Are there any other acne treatments you recommend that you know works? Thanks.

What skin type does proactiv best compliment? Dry skin? Oily? Combination?
