What is a good exfoliant containing benzoyl peroxide?

I have a ton of comedones on my face. Mainly on the sides of my chin. I've had them for YEARS and I'm just so fed up with them. I've tried Proactive. Did not do a thing. I've tried a lot of things, actually. All I want to know is what is a good exfoliant containing benzoyl peroxide? Id like to find something that has a lot of "scrub" to it...like St. Ives Apricot Scrub...but with the benzoyl peroxide. Any suggestions?
