Injection of hyaluronic acid rich risorius is a kind of injection of rich micro-plastic, which has no harm to the skin, but it cannot be maintained for a long time and needs repeated injection. Of course, the injection of risorius should be moderate and plump, because it needs to be coordinated with the face, otherwise it will destroy the harmony of the face and be very unsightly.

Second, autologous fat fills risorius.

Autologous fat is a little more complicated. Generally, liposuction starts from the abdomen and thighs, and then the fat is purified and injected into risorius. Most of the time, it is a deep injection. However, the advantage of autologous fat is that the effect of filling risorius with hyaluronic acid lasts longer. As long as it is a living fat cell, the effect is permanent. # Shujie Wang Badachu # # Autologous fat filling #
