On page 325 of "Optimal Wellness" Dr. Ralph Golan states that " Acne is a superficial manifestation of an internal imbalance . . . . concentrate on internal treatments and underlying causes." He recommends using a gentle glycerin soap daily to wash your face. For internal treatments, he recommends the following:
1. Dietary Recommendations. Follow a whole-foods (high-fiber) diet, emphasizing fresh fruits and vegetables. Drink (at least) six to eight glasses of (filtered) water a day. Drink green juices for their cleansing effects.
2. Detoxification Programs. Do an intestinal cleansing program; follow the Liver Flush and Purifying Diet (listed elsewhere in the book) and/or fast for several days periodically.
He also has two other categories of recommendations (nutritional supplements and herbal remedies) which I can give you in another posting if you are interested. I can also give you a lot of information on doing an intestinal cleansing program if you are interested.
