Doctors will inject different milliliters of hyaluronic acid according to each person's physical condition to achieve the effect of hyaluronic acid. Hyaluronic acid has a wide range of uses, which can be said to be a magical beauty relic given by God to the beauty industry. Hyaluronic acid can also keep the skin elastic, lock a large number of water molecules, 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:
Hyaluronic acid injection is a liquid for injection. The effect of wrinkle removal can be achieved by needle syringe. Hyaluronic acid injection can remove wrinkles and modify the face by injecting hyaluronic acid into wrinkles, depressions or parts of the dermis that want to become rich.
There are generally three methods for refining hyaluronic acid injection:
1, animal tissue.
The main raw materials are cockscomb and bovine vitreous. Defat that raw materials with acetone or ethanol, dehydrate, soaking in distilled water, filter, treating with sodium chloride aqueous solution and chloroform solution, adding trypsin to keep warm to obtain mixed solution, and finally treating with ion exchanger and purifying to obtain refined hyaluronic acid injection.
2. Microbial fermentation.
Fermentation broth with glucose as carbon source. Fermented in the culture medium for 48 hours, filtered to remove mycelium and impurities, and then obtained high-purity products through simple operations such as alcohol precipitation.
3. Chemical synthesis.
Adopt natural enzyme polymerization reaction. Firstly, the polysaccharide polymer was used to synthesize "hyaluronic acid oxocyclopentene derivatives", and then hydrolase was added to make the complex of derivatives and enzymes. Finally, the enzyme was removed from the reaction solution at 90 degrees Celsius, and hyaluronic acid injection was prepared.
