Take Burdock root and Evening Primrose oil supplements. This is an old Middle Eastern treatment that my mom learned from her coworker. Warning: these pills are giant, not so much fun to take, but it's so worth it. Take 2 Burdock and 1 Evening Primrose every morning and night for the first week. Then cut down to 1 Burdock and 1 Evening Primrose every morning and night. This is hard to keep up with, which is why I stopped taking these supplements for a while, and it takes about 2 weeks to see a change in your skin but KEEP UP WITH IT. Burdock is like a natural antibiotic and it kills the bacteria in your pores, allowing pimples to clear up and Evening Primrose brightens and moisturizes your skin. In addition to the supplements, wash your face twice a day, use an oil free moisturizer and drink LOTS OF WATER!
