Hyaluronic acid filling of the chin is safer and is a more popular plastic surgery method at present. The two main blood vessels in the chin come out from the chin hole, while there are not too many blood vessels in the deep periosteal layer. The injection is safer, simple to operate, without surgical incisions, and can improve the short, receding jaw, making the face more three-dimensional and vivid. However, the majority of beauty seekers should choose regular medical institutions and products, and inject the right amount of chin to ensure safety. After hyaluronic acid filling of the chin, local swelling and hardening may occur for a short time, and it will basically return to normal in about 1 week. In some patients, there will be granularity when touching the skin after hyaluronic acid injection, which is a normal reaction. In addition, after the injection, the activity of the chin should be reduced, and squeezing and rubbing are prohibited to facilitate chin shaping and maintain a longer period of time. Generally, hyaluronic acid can be maintained for about 1 year after filling, and candidates can have additional injections 11-12 months after surgery. As long as you choose regular medical institutions and products, the safety of hyaluronic acid chin filler is still very high compared to other parts of the body.
