At present, there are two main ways to fill the temple: one is hyaluronic acid injection, which is injected into the temple like an injection. Hyaluronic acid is an inherent component of human skin, and its main function is to keep water and moisture and keep skin smooth. Hyaluronic acid is divided into three types: small molecule, medium molecule and large molecule. Medium molecular hyaluronic acid is mainly used to fill temples. Microneedle injection is simple and convenient, but it also has complications of vascular embolism. Therefore, it is necessary to draw back strictly when injecting, and pay close attention to the changes of the condition after injection. Second, autologous fat filling: remove the fat from the body fat accumulation parts, such as buttocks, abdomen and inner thighs. Take it out, centrifuge it and inject it back into the temple. Because fat is its own, it will not produce rejection, and it is a good filling material. However, after injection into the temple, the fat will not survive completely, generally around 70%, so the effect may be somewhat discounted. At this time, you need to replenish fat again to achieve satisfactory results.
