Hyaluronic acid is a high molecular weight polysaccharide with D- glucuronic acid and N-acetyl-glucosamine as repeating structure unit. Because of the action of hydrogen bond between the monosaccharide in HA linear axle, HA molecular forms a rigid screw column structure in space. Strong hydrophilic properties exist due to the large amount of hydroxyl groups. Furthermore, HA has a special water binding function and binds its water very strongly, so that it has strong water retention. Theoretically its binding water capacity is up to 500 ml/g as an ideal natural moisturizing factor.

HA is also one important component of the skin. It can prevent skin from aging and improve the appearance and tactile sensation of skin.
A part of low molecular weight HA can penetrate into dermal layer to control the mid-metabolism, and make the skin moist, smooth and elastic. Therefore the cosmetic functions of HA are its resistance against skin wrinkles and its general health protection. HA is not only a good skin moisturizer, but also promotes cell' s metabolism of skin. So HA stands for bio-mimetic cosmetics.

Hyaluronic acid is a natural part of the human body why it is highly suitable for many applications within the field of medicine and related aids. It is used in ophthalmology, orthopedics and cosmetic surgery. With the researching and development of application in medicine area, hyaluronic acid`s application as HA-supplementation and medical treatment material will be one major stream in health care Industry.
