What exactly is hyaluronic acid

Women may see ingredients like hyaluronic acid in many skin care products, but what exactly is hyaluronic acid? It is actually what we call hyaluronic acid. In the past, we often heard about some celebrities injecting hyaluronic acid, which means that hyaluronic acid is very effective in keeping the skin elastic and youthful. Hyaluronic acid is a unique component in human skin. Once it is missing, the skin will become loose and wrinkled.

1. Hyaluronic acid is a high molecular polymer. It is a high-grade polysaccharide composed of units of D-glucuronic acid and N-acetylglucosamine. D-glucuronic acid and N-acetylglucosamine are linked by β-1,3-glycosidic bonds, and disaccharide units are linked by β-1,4-glycosidic bonds. The number of disaccharide units can reach as many as 25,000. The molecular weight of hyaluronic acid in the body ranges from 5,000 to 20 million Daltons.

2. Biochemical drugs with high clinical value are widely used in various ophthalmic surgeries, such as lens implantation, corneal transplantation and anti-glaucoma surgery. It can also be used to treat arthritis and speed up wound healing. Using it in cosmetics can play a unique role in protecting the skin, keeping the skin moisturized, smooth, delicate, tender and elastic, and has the effects of anti-wrinkle, anti-wrinkle, beauty care and restoring the skin's physiological functions.

The main functions of hyaluronic acid are as follows:

1. Improve joint function

2. Natural moisturizing lubricant

3. Prevent the occurrence of arteriosclerosis, pulse disorder, cerebral atrophy and other diseases.

Hyaluronic acid (HA) is one of the main matrix components of the human skin epidermis and dermis. Its physiological function is to allow water to enter the intercellular space and combine with protein to form protein gel, sticking the cells together, playing a normal cell metabolism role, maintaining cell moisture, protecting cells from pathogens, accelerating the recovery of skin tissue, improving wound healing and regeneration ability, reducing scars, and enhancing immunity. At the same time, hyaluronan is a major component of the extracellular matrix of proliferating and migrating cells, especially in embryonic tissues. Because of the characteristics of hyaluronic acid itself, it can keep cells separated from each other, make cells easy to move, migrate and proliferate, and prevent cell differentiation. During development, hyaluronan appears to prevent cells from prematurely differentiating before they have proliferated enough or migrated into position. In medicine, hyaluronic acid (HA) is used in non-steroidal anti-inflammatory drugs, arthritis treatment, ophthalmology, and auxiliary drugs for cardiac surgery. It has a unique effect in the treatment of scalds, burns, frostbite, artificial skin, etc.
