Try taking 50 MG of Chelated Zinc (here's some from Amazon: http://www.amazon.com/Natures-Bounty...727223&sr=8-2)
, it shows a lot success with a fair amount of people. You can google for more info, there are a lot of positive reviews on Acne.org.
Other than that, just use a standard Benzoyl Peroxide treatment and a moisturizer, along with a spot treatment.
