In cosmetic industry, the formulators are striving to get safer and more efficient cosmetic raw materials. Sodium Hyaluronate (HA), which is well-known as natural moisturizing factor, is just this kind of compound. Thanks to its multiple benefits in various branches of medicine, cosmetic and plastic surgery some have went as far as calling it “the key to the fountain of youth”.

Other less known properties of hyaluronic acid are to keep the skin hydrated and to improve bone density and muscle strength. Almost 50% of the bodie’s HA is found here. It is found in both the deep underlying dermal areas as well as the visible epidermal top layers. Young skin is smooth and elastic and contains large amounts of HA that helps keep the skin stay young and healthy. The HA provides continuous moisture to the skin by binding up to 1000 times its weight in water. With age, the ability of the skin to produce HA decreases
