Hyaluronic acid is an acidic mucopolysaccharide, which was first isolated from the vitreous body of the bovine eye. Most importantly, it has a special water-retaining effect, and it is the substance with the best moisturizing property found in nature, which is called an ideal natural moisturizing factor.

Hyaluronic acid​ is a chemical substance, and the molecular formula is (C14H21NO11) n, that is, a bisogaamine polysaccharide composed of D-glucosamidic acid and N-acetylide.

Hyaluronic acid helps reduce the visibility of fine lines and wrinkles, retains moisture for the skin, and produces a plumping effect. When the skin is protected and moisturized, the production of skin cells will increase because the skin will not be busy fighting for moisture.
