Hyaluronic acid is a non-sulfated glycosaminoglycan distributed widely throughout the body in the connective, epithelial, and neural tissues. It is one of the chief components of the extracellular matrix and contributes significantly to cell proliferation and migration. The average person has roughly 15 grams of hyaluronic acid in their body, one third of which is lost and replaced each day.
