The skin is the first line of defense against the aging process and the body’s pH is the thermostat that regulates the speed and progression of this process. Skin care systems can be used to create products with a synergistic effect to regulate the skins pH based on skin type. Creating the right prescription for the skin based on pH and appropriate concentration of active ingredients is the key to improved, younger-looking skin. Good health is not a luxury, it is a necessity. The skin protects a body’s internal clock against the aging process and we are the timekeepers.
