Hyaluronic Acid
Hyaluronic acid, or sodium hyaluronate, is a polysaccharide composed of long chains of N-acetyl-D-glucosamine alternating with glucuronic acid. In our skin, it stabilizes the intercellular (in-between cells) space in the dermis and contributes significantly to activities essential to skin health. Because of its tremendous capacity to hold water, adding this active to your creams, lotions, gels or serums will help keep skin moist. Low molecular weight hyaluronic acid is not hyaluronic acid. By definition, the molecular weight of hyaluronic acid is in the millions. Small fragments of broken hyaluronic acid can’t hold water or form gels.
