Different zit-zapping ingredients do different things for the skin: benzoyl peroxide (found in Clean and Clear Advantage 3-in-1 Exfoliating Cleanser, $8.49) banishes bacteria, salicylic acid (like in Benefit Cosmetics Boo Boo Zap!, $20) exfoliates to clear the pores, and sulfur (try MD Skincare Correct & Perfect Spot Treatment, $28) is antibacterial and helps reduce skin oiliness. Mess around with these ingredients until you find the right combo for you, or ask a dermatologist for their perfect recipe, since everyone is different.
