[Skin hydration and hyaluronic acid].
Skin hydration mechanism is complex. Hyaluronic acid is a widely distributed glycosaminoglycan and one of the chief component of the extracellular matrix. It has a high water retaining ability and has recently been shown to be present in the epidermis. HA plays a central role in hydration and elasticity of skin.
