Hyaluronic acid is found naturally in the fluid that bathes joints, in the vitreous humor of the eye and in the skin. Botanical hyaluronic acid is derived from a plant called Cassia Angustifolia (Senna Alexandria). Sodium hyaluronate is a powerful anti-aging ingredient in skin care. It is an irreplaceable hydrating ingredient because of its ability to attract and retain moisture. It protects the skin and helps restore youthfulness by plumping skin and giving it a smoother appearance.
