Brief introduction of Hyaluronic acid:
Hyaluronic acid, whose molecular formula is (C14H21NO11)n, is a disaccharide unit glycosaminoglycan composed of D-glucuronic acid and N-acetylglucosamine.
With its unique molecular structure and physicochemical properties, hyaluronic acid shows a variety of important physiological functions in the body, such as lubricating joints, regulating the permeability of blood vessel walls, regulating proteins, water and electrolyte diffusion and operation, and promoting wound healing.

Function of Hyaluronic acid:
1. Pharmaceutical
Hyaluronic acid is the main component of connective tissues such as interstitial cells, vitreous body, and synovial fluid of the human body. It plays important physiological functions in the body to retain water, maintain extracellular space, regulate osmotic pressure, lubricate, and promote cell repair.
As the main component of the intercellular matrix, hyaluronic acid directly participates in the regulation of electrolyte exchanges inside and outside cells, and plays the role of a filter for physical and molecular information. Hyaluronic acid has unique physical and chemical properties and physiological functions, and has been widely used in medicine.
2. Health care
The content of hyaluronic acid in the human body is about 15g, which plays an important role in the physiological activities of the human body. The content of hyaluronic acid in the skin is reduced, the water-retention function of the skin is weakened, and it appears rough and wrinkles; the reduction of hyaluronic acid in other tissues and organs can lead to arthritis, arteriosclerosis, pulse disorders and brain atrophy. Decreased hyaluronic acid in the human body produces progeria.
3. Cosmetic
Hyaluronic acid originally exists in the skin, which can help the skin absorb water from the body and the skin surface, and can also enhance the skin's long-term water retention capacity. When hyaluronic acid absorbs water, it makes elastic fibers and collagen in a moist environment, so the skin has elasticity. However, the hyaluronic acid of the skin begins to be lost after the age of 25. At the age of 30, only 65% of the infancy is left, and at the age of 60, only 25% is left. The moisture of the skin will also be lost along with the hyaluronic acid, and the elasticity will be lost. Glossy, the aging phenomenon of wrinkles will appear for a long time.
Application of Hyaluronic acid:
Hyaluronic acid can be used as a viscoelastic agent in ophthalmic intraocular lens implantation surgery, as a filler in joint surgery such as osteoarthritis and rheumatoid arthritis, and as a medium in eye drops, it is also used to prevent postoperative Adhesion and promotes healing of skin wounds. The compound formed by the reaction of hyaluronic acid and other drugs exerts a sustained release effect on the drug, and can achieve the purpose of directional and timed release. With the development of medical science and technology, the application of hyaluronic acid in medicine will become more and more extensive.
Hyaluronic acid also plays an important physiological role in other tissues and organs, such as lubricating water and retaining water, such as joint cavity, blood vessels, heart and brain. Decreased levels of HA in these tissues can lead to arthritis, arteriosclerosis, pulse disturbance, and brain atrophy. Oral HA can supplement the lack of HA in the tissue, delay aging, and make people energetic.
Due to the extrusion of age, smoking, sleeping, etc., and the traction of gravity, the loss of hyaluronic acid in the skin will cause the loss of hyaluronic acid in the skin, which will gradually reduce the collagen and elastic fibers of the dermis, causing skin relaxation and facial wrinkles. Acids are effective in addressing many types of wrinkles.
Rhinoplasty: Although the development of rhinoplasty technology has reached a certain height, since hyaluronic acid injection has been used for rhinoplasty, the advantages of hyaluronic acid rhinoplasty are fast, no surgery, and no pain. Prosthetic rhinoplasty, etc. Rhinoplasty presents certain challenges.
Human aging will cause changes in the distribution of subcutaneous tissue. The temples, cheeks, orbits, eyebrow arches, and around the lips will be sunken, and tear grooves will appear. Hyaluronic acid is used for facial filling including tear grooves, nasolabial folds, and puppet lines ( Women's three "eight" lines) are popular, and the effect is relatively good.
Lip augmentation: Generally speaking, human lips will shrink with age, wrinkles will appear, and the corners of the mouth will also sag due to aging. Hyaluronic acid filling lip augmentation has won certain praise.
Hyaluronic acid can also be used to fill some acne scars, trauma, scars caused by surgery, and asymmetry of birth defects.
