Hyaluronic acidis one kind ofpolysaccharides composed of repeat disaccharide units of N-acetylglucosamineand glucuronic acid Commercial HA is commonly its sodium salt form. Sodiumhyaluronate is the key water maintaining substances in human skin. Bad livingenvironment and aging can cause the decrease of HA content in skin, and as aresult the water maintaining ability of the skin is weakened and the akin looksdry and rough .One of the main causes of skin senility is also the decrease ofpolysaccharides, such as HA. The special structure characteristic of HA makesit has high moisturizing and water content reguating function and its solutionhas high viscoelasticity and lubricity. When HA solution is applied on thesurface of skin, it can form an air permeable layer and keep the skin moist andsmooth. Small molecular weight HA can penetrate into dermis layer, fullycombine with water, promote skin blood microcirculation and nutrient absorptionand maintain normal metabolism, and as a result it plays a role of wrinkleremoving, look improving and health protecting. Topical grade HA can be used in many kinds of cosmetics, such as cream, milk,water shampoo, lotion, etc. HA is one of the best natural moisturzingcomponents used in cosmetics.
