Hyaluronate Acid is the key water maintaining substances in human skin. Bad living environment and aging can cause the decrease of HA content in skin, and as a result the water maintaining ability of the skin is weakened and the akin looks dry and rough .One of the main causes of skin senility is also the decrease of polysaccharides, such as HA. The special structure characteristic of HA makes it has high moisturizing and water content reguating function and its solution has high viscoelasticity and lubricity. When NaHA solution is applied on the surface of skin, it can form an air permeable layer and keep the skin moist and smooth.
