Hyaluronic Acid

With collagen, elastin and proteoglycans, hyaluronan is the basic substance of the dermis. It plays a vital role in water regulation of the skin because it has an outstanding water retention capacity. It works like a real "molecular sponge", absorbing up to 1000 times its weight in water. It keeps its moisturizing activity even in a dry atmosphere. Topically, hyaluronic acid forms on the skin a continuous film, elastic and permeable skin exchanges, which holds water and thus contributes to maintain a good level of hydration of the stratum corneum regardless of the ambient humidity.
