What are some good acne products?

I have really oily/ acne prone skin and nothing seems to keep my pimples away! I have Proactiv but its not helping and i had been using a prescription medicine (Clindamicin) and that didn't help either! I have tried several drug store washes and creams like Oxy, AcneFree,etc, but i still get quite a bit of acne... Please help!!
