Hyaluronic acid originally exists in human skin, which not only does not produce rejection reaction with human body, but also helps skin absorb moisture in body and skin surface, enhances skin's long-term water retention ability, and makes elastic fibers and collagen in skin in a moist environment, making skin elastic. And hyaluronic acid has another name, hyaluronic acid, so hyaluronic acid and hyaluronic acid are the same thing. The role of hyaluronic acid says that hyaluronic acid has a powerful anti-wrinkle effect. In fact, the role of hyaluronic acid is not only wrinkle removal, but also has a place in other beauty aspects. According to plastic surgery experts, hyaluronic acid originally existed in human skin. Appropriate supplementation of hyaluronic acid to human skin can not only help the skin absorb a lot of water from the skin surface, but also enhance the skin's long-term water retention ability. Hyaluronic acid has other functions besides wrinkle removal and water locking. For example, it is said that injection on the bridge of the nose can play a role in rhinoplasty; Injecting hyaluronic acid into the lips can enrich the lips, which is the role of hyaluronic acid. The reason why hyaluronic acid has so many effects is related to its structure. The scientific name of hyaluronic acid is hyaluronic acid (HA) or uronic acid, which is a linear macromolecular polysaccharide composed of disaccharide units (glucuronic acid -N- ethylthioglucosamine). It is a naturally occurring substance in tissues, which has the functions of moisturizing and shaping. The above is an introduction to the question whether hyaluronic acid and hyaluronic acid are the same thing. I believe that through the above introduction, you who love beauty will have a deeper understanding of it. But whether it is hyaluronic acid or hyaluronic acid, their effects and functions are unchanged.
