MOISTURISERS > Hyaluronic Acid (HA)

Hyaluronic Acid (HA) is a naturally-occurring polyanionic polysaccharide. It is present in the intercellular domains of connective tissues and especially in the skin. Because of its unique rheological, viscoelastic and hygroscopic properties, HA plays a key role in protecting and stabilizing the skin at the cellular level.
