Only a small incision of 2mm is needed, and a thin fat suction tube is inserted, so that a layer of fat can be sucked evenly. After operation, gauze will be used externally and pressure will be applied. Take antibiotics orally for 3 days, and try to avoid touching the surgical site after operation.
