玻尿酸-透明质酸

Hyaluronic acid (HA) is produced by keratinocytes and is a member of a large family of glycosaminoglycans, the main components of the extracellular matrix. It is abundant in tissues and fluids, with the highest concentrations in synovial fluid, vitreous humor and skin. HA helps to support joint health and provides supplemental support for skin health.
