Only 20% of the skin (the epidermis) can be reached by topical products. The rest is strengthened through healthy nutrition; in fact, studies have demonstrated that eating pomegranates can even increase the SPF of sunscreens! Providing your body with the right raw materials, such as raw fruits and vegetables, allows it to maintain a healthy water balance, stimulate new cell growth, and repair vital structures—including replenishing your skin. Healthy skin is a reflection of overall wellness.

As the body’s largest organ, the skin benefits greatly from its nutritional intake. Science shows that nutrients such as vitamins A, C and E, amino acids and essential fatty acids are imperative for the synthesis of the three major components of the skin: collagen, elastin and glycosaminoglycans. These nutrients are delivered to the dermis by microcirculation and then picked up by the epidermis through other complex biochemical processes in the skin, resulting in a healthy, radiant complexion from the inside out.
