Acne in an adult may be caused by a fungal overgrowth in the body.
Research and experience has also been clear that many skin conditions are common with a low digestive enzyme level of stomach acid called HCl ( Hydrochloric Acid). The support given with this enzyme allows the stomach to breakdown food and calcium better and the skin is often improved.
Protocols we successfully used for years includes high Potency stomach enzyme called Hydrochloric Acid (HCl), Vitamin A, Zinc, and Bio Immunozyme Forte.
 Magnesium and Vitamin E are also common deficiencies.
