For example, lubricate joints, regulate the permeabilityof the blood vessel wall, regulate protein, water electrolyte diffusion andoperation, promote wound healing and so on. More importantly, hyaluronic acidhas a special role in water conservation, which is the best moisturizingsubstance found in nature, and known as an ideal natural moisturizing factor.Its hyaluronic molecules can carry more than 500 times of water, so it is widelyused in cosmetics. Hyaluronic acid is a multifunctional matrix, widely distributed inthe human body. Of which the skin also contains a large amount of hyaluronicacid. The process of human skin maturation and aging also changed withhyaluronic acid content and metabolism, it can improve skin nutritionmetabolism, make the skin soft, smooth, remove wrinkles, increase elasticityand prevent aging. Used in conjunction with other nutrients, may help toachieve the desired effect of promoting nutrient absorption. Hyaluronic acid itself has a negative charge,present in most of the soft tissues in the animal body. Its aqueous solution isviscoelastic fluid, filled in the space between cells and collagen fibers andcovering in some skin tissue. In animals, its main function is to protect andlubricate cells, regulate the cell movement in this viscoelastic substrate,stable the collagen network structure and protect it from mechanical damage.Hyaluronic acid is widely distributed in the body connective tissues, almost inthe form of pure state exists in the vitreous, joint cavity. The hyaluronicacid in the skin plays an important role in the epidermis metabolism of thehuman body. The hyaluronic acid destruction or disorder in the body can causedisease. The hyaluronic acid content reduction or damage in the skin can causeskin dehydration, wrinkles and loss of elasticity, makes skin aging. Thus,hyaluronic acid is also known as anti-aging factor. Hyaluronic acid is one of the major matrix components of human skin epidermisand dermis. Its physiological function is to allow water entering the cellsgap, and combined with proteins to form a protein gel, stick the cellstogether, play the role of normal cell metabolism, have the effects that keepcells water, protect cells from pathogens violations, accelerated to recoverskin tissue, improve wound healing regenerative capacity, reduce scarring,enhance immunity, etc. In pharmaceutical raw materials aspects, hyaluronic acid used as non-steroidal anti-inflammatorydrugs, and auxiliary drugs on arthritis treatment, ophthalmology, cardiacsurgery, has a unique effect in the treatment of scald, burns, frostbite,artificial skin, etc. By the influence of people grow older and the factors of nutrition,sunshine, environment and so on, the body's ability to synthesize hyaluronicacid decreased, the content of hyaluronic acid in the skin will be graduallyreduced, human in embryo period has the highest concentrations of hyaluronicacid, and gradually decreased after birth. If positioning the relative contentof hyaluronic acid to 100% in 20 years old people, then the 30,50,60 age willrespectively decrease to 65%, 45%, 25%. When hyaluronic acid in the skin belowa certain level, the water content of the skin surface will be graduallyreduced, causes the stratum corneum aging, the skin becomes rough, appearswrinkles, loss of elasticity, looks senility, this phenomenon generally occursafter the age of 25. This is also one of the reasons that the gap between theelderly and children's skin. While the destruction of hyaluronic acid in theskin is related to UV, so people who were long-term engaged in field work,highland life have very rough skin, outdoors operations staff' compared withindoors officer, their skin also look more rough.
