The operation process of autogenous fat augmentation is about 1- 1.5 hours. Local anesthesia or general anesthesia can be used in the operation, and there is no pain during the operation. Autologous chin fat does not need hospitalization, but follow-up treatment is enough. It usually takes 7- 14 days to recover, and the effect can be fully presented in about 3 months. Some fat will be absorbed, but the remaining fat is effective for life.
