Hyaluronic acid (hyaluronic acid) is an acid mucopolysaccharide. In 1934, Meyer et al., a professor of ophthalmology at Columbia University in the United States, first isolated the substance from the vitreous body of bovine eye.
Hyaluronic acid with its unique molecular structure and the physical and chemical properties showed a variety of important physiological functions in the body, such as lubricating joints, adjust the permeability of blood vessel walls, regulating protein, diffusion and operating of the electrolyte to promote wound healing, etc.
Is particularly important, has a special role in water, hyaluronic acid moisturizing effect found in nature: is the best material, known as the ideal Natural moisturizing factor (Natural moisturizing factor, NMF, for example: 2% pure hyaluronic acid aqueous solution can firmly maintain 98% moisture.
Hyaluronic acid (hyaluronic acid) is a multifunctional matrix. Hyaluronic acid (hyaluronic acid) HA is widely distributed in various parts of human body.
The skin also contains a lot of hyaluronic acid.
Mature human skin and aging process also changes with the content of hyaluronic acid and metabolism, it can improve skin nutrition metabolization, make the skin soft, smooth, remove wrinkles, increase elasticity, prevent aging, while moisturizing and good transdermal absorption promoting agent.
When used in combination with other nutrients, it can promote better absorption of nutrients.
