Hyaluronic acid itself is the composition of the human skin, is widely distributed in the body of a - a kind of acidic fucose, exists in the matrix of connective tissue, has a good moisturising effect. It is internationally known as the ideal natural moisturising factor. It is the best moisturising substance in cosmetics found in nature.
Hyaluronic acid (HA for short) is a mucopolysaccharide composed of N-acetylglucosamine and glucuronic acid disaccharide repeating units, commercial HA is usually its sodium salt form, called sodium hyaluronate. HA is widely found in the interstitium of animal tissues and the vitreous body of the eye, and its main physiological functions are water retention and lubrication. 75% of the fluid in the human eye is hyaluronic acid.

Food grade:
1.Hyaluronic acid powder is a substance that is naturally present in the human body. It is found in the highest concentrations in fluids in the eyes and joints.
2. The hyaluronic acid that is used as medicine is extracted from rooster combs or made by bacteria in the laboratory.
3.Hyaluronic acid powder is also used as a lip filler in plastic surgery.It is also using to prevent the effects of aging.
4.Hyaluronic Acid powder (HA, Hyaluronic, Cyclic Acid) is a critical component of the skin that helps to retain moisture, keeping the skin firm, and preventing wrinkles by adding volume to the skin.
