Hyaluronic acid CAS NO.9004-61-9

Hyaluronic acid(HA) is a straight chain macromolecular mucopolysaccharide composed Of repeat disaccharide units of glucuronic acid and N-acetylglucosamine. It widely consists in the extracellular space of human and animal tissue, vitreum, umbilical cord, skin joints synovia and cockscomb, etc. The commercial HA is commonly a sodium salt, called sodium hyaluronate, habitually called hyaluronic acid. HA is a new biological at home and abroad. Its molecular weight is from several ten thousand to several million. It's aqueous solution has outstanding moisture keeping ability, high viscoelasticity and lubricity. It is widely used in cosmetics, pharmacy and health and beauty food. 

Hyaluronic acid is a type of polysaccharide called a glycosaminoglycan. Also known as hyaluronan or hyaluronate, it occurs naturally in the human body and is central to regulating cell growth and renewal. In fact, it is found extensively in connective, epithelial, and neural cells. As such, hyaluronic acid has found its way into many skin care products, particularly anti-wrinkle formulations. In addition, it has been credited with extending life in those who consume high amounts in the diet, resulting in the media dubbing it as the "fountain of youth."

Originally used only hyaluronic acid moisturizing effect , has been included in the ranks of the wrinkle plastic material , this plastic surgery technique is the use of bacterial fermentation stability fostered non-animal hyaluronic acid, hyaluronic acid by way of filler injected into the dermis wrinkles depression or want rich site, in addition to wrinkles and modified to achieve the effect of the face , can instantly change the appearance of wrinkles and . Hyaluronic acid, originally to gel form found in human skin dermal tissue , is responsible for storing water, increasing the volume of the skin , so skin looks plump , rich, flexible. However, hyaluronic acid will disappear with age , the skin loses its ability to store water , and gradually becomes dull , aging, and the formation of fine wrinkles. And thanks to the progress of biotechnology , from vertebrate connective tissue, such as comb , eye , umbilical cord, cartilage and other parts, hyaluronic acid can be extracted . The last source of hyaluronic acid extracted from multiple animals , and now by a synthetic , aside allergy and infection.

With the development of technology, hyaluronic acid injectable fillers can have not just used , has developed a topical hyaluronic acid . This topical hyaluronic acid containing hyaluronic acid , SOD, cell growth factor particles and other cosmetic ingredients . Use the crowd is no longer simply just want to tuck breast of the crowd, the crowd could be the use of topical hyaluronic acid skin yellowish, rough , dull, wrinkles, dark spots and some contain face Amy . Generally speaking , although the loss of traditional topical hyaluronic acid hyaluronic acid -filled breast cosmetic effect , but it applies to more people .
Hyaluronic acid, is one component of human dermal tissue .

Water is the source of life, aging body will gradually lose moisture, keeping the moisture of the most important human tissue material is hyaluronic acid . Increase the body 's levels of hyaluronic acid decreases with age , and thus lead to dry skin and wrinkles. Moisture is the first step skin care , healthy skin moisture content should be maintained at about 15 to 20% , hyaluronic acid moisturizing effect is 16 times collagen , water retention value of up to 1000cc / g, is today the best moisturizing accepted literature products, due to hyaluronic acid in the skin can maintain long-term health condition , it is called the "best moisturizing factor ."


1. to maintain skin elasticity :
After oral administration of hyaluronic acid to absorb moisture , so that the collagen and elastic fibers in a humid environment is filled , the complementary external collagen synthesis of collagen itself provides a suitable environment , to improve the utilization of collagen, skin, and therefore has elasticity. The role of hyaluronic acid also reflected out .


2. water, water lock capability :
The most important role of hyaluronic acid is water retention , water lock . Oral hyaluronic acid can lock a lot of water molecules , not only to keep the moisture within the skin , but also the external environment to capture water to live, so that the skin long kept moist state, enhance water retention capacity of the skin.
