Hyaluronic acid chin plastic can take effect on the spot, does not need a recovery period, does not affect daily work and life after injection, has a natural chin augmentation effect, and is softer and more realistic than ordinary prosthesis chin augmentation. The injected hyaluronic acid comes from biological tissue, so the human skin tissue will not produce positive rejection, which is very safe and has no side effects. More importantly, hyaluronic acid is comfortable and painless, and it is injected. It's the same as an injection, but there is slight swelling and pain locally.
