3. Application:
Hyaluronic Acid (HA) is a mucopolysaccharide composed of repeated disaccharide units of N-acetylglucosamine and glucuronic acid. The commercial HA is commonly a sodium form, called sodium hyaluronate. HA is widely presents in the extracellular matrix of animal tissues and vitreous humor. Its main physiological function is water retention and lubrication.
Low molecular weight sodium hyaluronate (LMWHA) can penetrate dermis to be absorbed easily by the skin. By improving blood circulation, regulating skin metabolism and ameliorating skin nutrition, LMWHA can prevent the skin aging and maintain the collagen function.
LMWHA is particularly useful in beauty parlors because of its character of penetrating dermis easily. Imported by skin conditioners with the assistance of low voltage impulse or heat, LMWHA can improve the generation of new cells and resist aging so as to let skin feel its true value
HA in human body is high molecular weight substance. LMWHA can be synthesized into HMWHA after being absorbed by body, so the amount of entogenous HA increases. The nourishing of LMWHA acts on the whole body from the dermis to the epidermis.
