Your skin has similar needs to the rest of your body. However, because of your skin’s unique barrier functions, your skin requires its own nutritional support to maintain its balance and to keep it young and healthy. Your skin also needs regular maintenance to keep the outermost layers of your epithelium looking smooth and even and for optimal skin health. These periodic treatments are needed every four to six weeks because your skin cells turn over and rebuild themselves every 28-40 days (depending on your age).
