Abstract

The invention relates to an injection containing amino acid and sodium hyaluronate and a preparation method of the injection, and belongs to the technical field of medical beautifying and biomedicine.The injection containing the amino acid and sodium hyaluronate is mainly prepared from, by weight, 1.7-17.2 parts of glycine, 0.5-5.2 parts of L-proline, 2.0-20.0 parts of L-leucine, 1.8-17.6 parts of L-lysine, 20.0-200.0 parts of sodium hyaluronate, 3.6-35.8 parts of an excipient, 1.4-14.3 parts of a stabilizer and 1,000 parts of injection water. The injection containing the amino acid and sodium hyaluronate is prepared by means of the method and can achieve quick filling, remove wrinkles, striae gravidarum and other flaws on the skin, promote the growth of new skin cells and promote the youthfulness of the facial state and has an anti-aging function.

Description

technical field [0001] The invention belongs to the technical fields of medical cosmetology and biomedicine, and specifically relates to an amino acid-containing sodium hyaluronate injection and a preparation method thereof. Background technique [0002] It has become a common phenomenon to correct soft tissue defects and repair aging and wrinkled skin through plastic surgery technology, so as to maintain the perfect and youthful facial shape. Among various plastic surgery techniques, injection beauty technology accounts for the largest proportion, accounting for about 40% of the entire beauty market. Injection beauty technology is a beauty technology that partially modifies the human body through injection to achieve exquisite local shape and harmonious overall shape. This technology has the characteristics of zero recovery, quick effect and high safety, and is the first choice for beauty needs. [0003] Injection cosmetology is a kind of non-surgical plastic cosmetology....
