A standard facial cleanser won't address the needs of oily skin. And too harsh a wash might strip away all the oil (which only sends your oil glands into overdrive). Look for a clay-based cleanser that's designed to absorb excess oil. This one, from Jack Black, uses Kaolin clay and volcanic ash to sop up grease and grime while reducing sebum production. Glycolic acid and tea-tree oil also clear away dead skin cells and prevent breakouts.
