Although Hyaluronic Acid (HA) can be found naturally in most every cell in the body, it is found in the greatest concentrations in the skin tissue. Almost 50% of the bodies HA is found here. It is found in both the deep underlying dermal areas as well as the visible epidermal top layers. Young skin is smooth and elastic and contains large amounts of HA that helps keep the skin stay young and healthy. The HA provides continuous moisture to the skin by binding up to 1000 times its weight in water. With age, the ability of the skin to produce HA decreases.

Unlike collagen, Hyaluronic Acid is able to penetrate the skin’s upper layers to improve and benefit the skin when applied topically. When applied in an HA cream or serum, hyaluronic acid forms an air permeable layer and penetrates into the dermis, thus boosting the elasticity and hydration of the skin. The protective barrier on the skin locks in moisture, which gives the skin a youthful appearance.
