Product Details
Introduction and Application
Hyaluronic acid is a high molecular weight acidic mucopolysaccharide composed of N-acetylglucosamine and D-glucuronic acid disaccharide units repeatedly connected. It is an emerging advanced biological product at home and abroad, with a molecular weight of several thousand to several million. Its aqueous solution has extremely high moisturizing, viscoelasticity and lubricity.
Small molecule hyaluronic acid can penetrate into the dermis, promote skin nutrient absorption, has a strong wrinkle-removing function, can increase skin elasticity, and delay skin aging.
Uses: It can be widely used in health food, medicine, cosmetics and other industries.
