Generally speaking, 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. The average molecular weight is between 6,543.8+10,000 and 6,543.8+10,000 daltons, which exists in intercellular spaces. Generally, hyaluronic acid can absorb 300-500 times of water, keep the skin highly saturated, rebuild the water-fat care film, and make the skin healthy, delicate and shiny. Hyaluronic acid originally exists in human body, especially in dermis. However, with the increase of age, hyaluronic acid will gradually lose and the skin will be easy to dry. Therefore, adding synthetic or vegetable hyaluronic acid to cosmetics can have a particularly good moisturizing effect.
