Lissolis is a place that needs flexibility and elasticity, so the closer it is to the filler of human tissue, the better the effect will be. In Hong Kong and Taiwan, risorius injection is mainly composed of macromolecular hyaluronic acid, and the maintenance effect can reach 1 year or even longer, because individual physique is different; In Chinese mainland, both hyaluronic acid and collagen molecules approved by the National Medical Products Administration were used to mold risorius, and the effect was quite good.

2. Autologous fat transplantation. Generally speaking, autologous fat transplantation can maintain the effect for a long time. During the operation, only a small amount of C.C. fat needs to be extracted from fat-rich parts such as thighs or buttocks, and then injected into risorius. The operation only needs local anesthesia. For example, if the cheekbones are high, the facial expression will appear serious. Therefore, as long as you fill some fat and slightly disperse the high cheekbones, you will create the effect of risorius, and the facial lines will immediately become much softer.

At this time, the permanent implant sometimes becomes unable to blend with the face, resulting in an unnatural appearance.
