Hey girls!

I have acne prone skin which has been clearing up nicely due to a acne-busting recipe I found on acne.org...however I'm in desperate need of an exfoliant. The Benzoyl peroxide is doing wonders for my acne, but completely drying out the affected areas. My skin is a lot clearer, but I can feel the tightness and drying affects. I was wondering if anyone could recommend a gentle exfoliant that won't be too harsh for my sensitive skin?
