Hyaluronic Acid is present in every tissue of the body with more than 50% being found in the skin. As we age, there is a decrease in synthesis of hyaluronic acid as well as a recompartmentalization from the epidermis to the dermis. This HA depletion can result in thinning, aging, and decreased moisture in the skin. Low molecular weight HA found in many Arrestage products is able to efficiently diffuse into the epidermis and effectively hydrate the skin.
