Acne is often the result of a stressed liver. Greasy, fatty foods, chocolate, junk food, and foods with lots of preservatives are all hard on the liver and tend to have acne associated with them. The most obvious thing to do is eat healthy foods, but something else you can do, which I have had personal success with, is drink detox tea once or twice a day for no more than 2 or 3 weeks consecutively . . . If you go too long drinking detox everyday, there may be adverse effects. The tea box will usually also have directions. Detox tea is made with herbs that cleanse and promote the healthy functioning of the liver and kidneys. My acne starts to go away after about a week of drinking detox tea twice a day (it depends on how bad my acne is). Most markets have Detox Tea, although I usually buy mine from Whole Foods. Traditional Medicinals, Yogi, and Triple Leaf have good detox teas.
