Traditional Use
Discovered in 1934 in bovine eye tissues; originally identified as a component of the extracellular matrix. Recognized in skincare from the 1990s onward for its exceptional water-binding capacity, inspired by the body's natural hyaluronic acid found in skin, joints, and connective tissue.
