1. Hyaluronic acid is a transparent and viscous colloidal substance and a macromolecular polysaccharide. It is a linear macromolecular polysaccharide with glucuronic acid -N- glucosamine acetate as disaccharide molecular unit, with an average molecular weight of 65438+ million ~10000000000 dalton (mass unit), which is filled in the gap between human cells and collagen fibers.
2. The price of hyaluronic acid plastic surgery mainly depends on the amount of hyaluronic acid. Because hyaluronic acid plastic surgery is not only to increase the bridge of the nose, but also to consider the tip of the nose, and different people have different requirements for the height of the bridge of the nose, so the dosage of hyaluronic acid is different. But in general, it is better to use 1-2 pieces of hyaluronic acid as a whole.
3. Hyaluronic acid can not only keep the skin elastic, but also lock a large number of water molecules, which can moisturize and lubricate tissues and make the skin full, young and elastic. However, with the increase of age, when the loss rate of hyaluronic acid is faster than the growth rate, the skin will gradually dehydrate, lose luster and elasticity, and wrinkle and other aging phenomena will appear for a long time.
Extended data
Function and efficacy of hyaluronic acid
1, maintain skin elasticity
After hyaluronic acid absorbs water, elastic fibers and collagen are in a moist environment, which provides a suitable environment for collagen supplemented by the outside world to synthesize its own collagen, improves the utilization rate of collagen and enhances the elasticity of skin.
2, hydrating and locking water for the skin
The most important function of hyaluronic acid is to keep and lock water. Hyaluronic acid for external use or oral use can lock a large number of water molecules, which can not only keep the moisture in the skin, but also capture the moisture in the external environment, keep the skin moist for a long time and enhance the skin's water retention ability.
3, filling the skin and soft tissue
Hyaluronic acid has great potential to replace collagen, placenta and botulinum in medical and cosmetic fields. Hyaluronic acid has the characteristics of insolubility, low metabolic rate, high water absorption, high water retention and difficult tissue transfer.
