Can't say if it works as I never had the problem, but an old wifes tale says a green apple diet clears the colon of toxins which causes ance. I heard you go on a green apple detox diet where you basically eat green apples every day, googled and found a similar story. As usual, use it dont use it..
Some people believe that green apples are extremely good for preventing and fighting existing acne both on your face and around the body. To avoid acne, eat one green apple a day (cut it into slices if need be and eat it throughout the day). And to reduce existing acne, cut a green apple into quarters and rub two of those quarters over the acne areas. If needed, use the rest, or just eat them. Combine this with drinking plenty of water to achieve clear skin.
