Under normal circumstances, slim masseter muscle surgery mainly involves making an incision inside our mouth, then removing the hypertrophic masseter muscle of the face appropriately through this incision and suturing it up. As for whether there will be pain during the surgery, we actually don't need to worry about it. The surgery is performed under local anesthesia, so there will be no pain during the procedure. The Korean-style face-altering surgery launched by Hangzhou Huashan Medical Beauty Hospital integrates the three-dimensional stereoscopic facial aesthetics design standard and professional minimally invasive technology on the basis of traditional surgery, allowing us to enjoy the process of face slimming without any worries about scars.
