Hyaluronic acid is a kind of acidic sticky polysaccharide, which was first separated from the vitreous of Bovine Eye by the 1934 American Columbia University's ophthalmology Professor Meyer. Hyaluronic acid with its unique molecular structure and physical and chemical properties in the body to display a variety of important physiological functions, such as lubrication joints, regulate the permeability of vascular wall, regulate protein, water electrolyte diffusion and operation, promote wound healing and so on. It is particularly important that hyaluronic acid has a special water conservation effect, which is the best moisturizing substance found in nature, known as the ideal Natural moisturizing factor (Natural moisturizing factor, NMF, for example: 2% of pure hyaluronic acid aqueous solution can hold 98% moisture firmly.
Hyaluronic acid is a multifunctional matrix, HA is widely distributed in all parts of human body. The skin also contains a lot of hyaluronic acid. Human skin maturation and aging process also with hyaluronic acid content and metabolism changes, it can improve skin nutrition metabolism, make skin soft, smooth, wrinkle, increase elasticity, prevent aging, in the moisturizing at the same time is a good transdermal absorption promoter. In conjunction with other nutrients, it can be a better effect in promoting nutrient uptake.
