Natural hyaluronic acid is a kind of macromolecular polysaccharide, which is a linear macromolecular polysaccharide composed of glucuronic acid -N- glucosamine acetate as disaccharide molecular unit. Hyaluronic acid originally exists in the dermal tissue of human skin in the form of colloid, which is responsible for storing water, increasing skin volume and making skin look full, plump and elastic.
However, hyaluronic acid will disappear with the increase of age, making the skin lose its water storage capacity, gradually becoming dull, aging and forming fine wrinkles.
