What is hyaluronic acid and what effect does it have on the skin? This is what the patients in the consultation group want to know. Hyaluronic acid (HA) or uronic acid is a linear macromolecular polysaccharide composed of disaccharide units (glucuronic acid -N- ethylthioglucosamine), which is a naturally occurring substance in tissues. It can effectively moisturize and wrinkle. Hyaluronic acid makes the skin look full, plump and elastic, thus making people look young. Hyaluronic acid is a kind of cosmetic material that cosmetic doctors often prefer in micro-plastic surgery. According to the clinical trials of hyaluronic acid by beauty experts for many years, hyaluronic acid has a particularly ideal effect in supplementing skin moisture. Nowadays, people who use hyaluronic acid for beauty are particularly extensive. The homogeneous molecular weight of hyaluronic acid is between 654.38+ 10,000 and 654.38+10,000 daltons, and it exists in intercellular spaces. Originally used only for moisturizing, it has now been included in the ranks of wrinkle removal and plastic surgery. This plastic surgery technique is to use the non-animal stable hyaluronic acid fermented by bacteria to inject hyaluronic acid into the wrinkles, depressions or parts of the dermis that are expected to be rich, so as to achieve the effect of removing wrinkles and modifying the face, which can immediately eliminate wrinkles and change the appearance. Because hyaluronic acid exists in the dermal tissue of human skin in the form of colloid, injection of hyaluronic acid will not have harmful side effects on the body. Hyaluronic acid is not always abundant in human body, and it disappears with the increase of age, which makes the skin lose its ability to store water. Therefore, it can be found that the skin of the elderly gradually becomes dull and aging, forming fine wrinkles. Friendly reminder: for your beauty and health. Please carefully choose plastic surgery hospitals and plastic surgery projects!
