Function and Usage:

Hyaluronic Acid (HA) is a special mucopolysacharide that is the normal lubricant in human joints. When present in a joint, even a joint with minimal or no cartilage, it can provide a cushion effect.
Cosmetics Use: HA is extensively used by the cosmetic industry and by dermatologists in anti-aging and moisturizing products as HA is very hydroscopic (absorbs and retains water).

Medical Use: HA helps control cell migration which protect cells and also activates the white cells. Since HA is an endogenous substance, it can be used to reduce the need for antibiotics by stimulating the immune system.HA aslo can reduce bacterial infections and has been found to inhibit the growth of a variety of strains of bacteria. It has also been concluded that HA even reduced the number of chronic bronchitis infections in patients.

Description

Hyaluronic acid is a long, stringy, gel-like disaccharide (a type of sugar) composed of alternating molecules of Glucosamine and Glucuronic Acid and is responsible for the viscoelastic behaviour of Synovial Fluid ("joint oil") and the hydration and elastic strength of cartilage.

Hyaluronic acid has traditionally been derived from type II collagen sourced from Rooster comb. This type of hyaluronic acid has a very high molecular weight of up to six million Daltons (the unit of measurement for molecular weight).

This form of hyaluronic acid has been shown to be effective when injected but has too large a molecular weight to be effectively absorbed through the intestinal tract - if you are going to take something as an oral supplement it has to get from your intestines into the bloodstream and then into the cells of the joints where it is needed!

化妆品方面作用：透明质酸为天然性润滑以及吸震高分子，在肌腱、肌腱鞘及粘滑膜表面作为润滑剂，皮肤中的透明质酸（玻璃酸）HA，对人体表皮的新陈代谢起到重要的作用。人体中透明质酸（玻璃酸）HA的破坏或失调，均可造成疾病。皮肤中透明质酸（玻璃酸）HA含量的减少及破坏，可造成皮肤失水中，起皱而失去弹性，使人表皮衰老，因而，透明质酸（玻璃酸）HA又被称为抗衰老因子。透明质酸（玻璃酸）HA是人皮肤表皮及真皮的主要基质成分之一，其生理功能是能使水分进入细胞间隙，并与蛋白质结合而形成蛋白凝胶，将细胞粘在一起，发挥正常的细胞代谢作用，起到保持细胞水分，保护细胞不受病原菌的侵害，加快恢复皮肤组织，提高创口愈合再生能力，减少疤痕，增强免疫力等作用。
