Autologous fat-rich risorius is adipose tissue extracted from other fat-rich parts of the body by high-definition scanning liposuction. After careful selection and repeated screening, it is full of active cells, and after strict treatment, it is transformed into fat particles and injected into risorius on the cheek to achieve a natural and round face shape. Generally speaking, autologous fat transplantation can make the effect lasting. During the operation, just extract a few milliliters of fat from the fat-rich part and inject it into the position of "Risolius". During the operation, only local anesthesia is needed.
