Zinc. When my son was going through the 'terrible teens', I gave him some zinc supplements and it did help to clear his face/chin up. Zinc will deplete your body's copper, so consult your doctor; if he/she says: "eat 3 well balanced meals, take 2 aspirins and call me in 3 weeks." do some web searching.
