Tetra Hexydecyl Ascorbate (Thd) (Oil Soluble Vit-C)

Tetra hexyldecyl Ascorbate (THDA or THD Ascorbate) is a highly stable, oil-soluble derivative of Vitamin C. Unlike pure Ascorbic Acid, it readily dissolves in oils and penetrates through the skin’s lipid barrier more effectively. Once absorbed, skin enzymes gradually convert it into active Vitamin C.
