In clinic, it is found that the imported hyaluronic acid has a high purity, and its effect can generally last for 2 to 3 years if the chin is padded. However, the purity of hyaluronic acid in China is low and there are many impurities. Therefore, this hyaluronic acid chin pad can only be used for about 8 to 16 months.

How long the effect of uric acid pad chin will disappear, or how long the effect of hyaluronic acid pad chin can last, is actually related to the quality of hyaluronic acid injection. If the quality of hyaluronic acid is good, the purity of hyaluronic acid will be high. This hyaluronic acid pad will be slowly absorbed and consumed by the human body, and the effect will be natural and lasting. If the purity of hyaluronic acid is low, the human body will quickly absorb and decompose hyaluronic acid, which will pad the chin.

Experts pointed out that it is very important to control the dose when injecting hyaluronic acid. During the operation, the dose of a needle is generally dispersed, which may take three or four points. After hyaluronic acid is put in, the doctor helps the beauty seeker to shape by hand. The doctor must pinch out the chin of the beauty seeker as soon as possible before the hyaluronic acid hardens, and the effect can be seen immediately after the molding is completed. Hyaluronic acid pad chin can be shaped several times depending on people, mainly related to the doctor's technical level and postoperative nursing work.
