Hello, the wounds for liposuction and weight loss generally need to be in hidden areas. A small incision of 0.5-1cm is selected (only 1-2 stitches are needed), and the suction tube is inserted under the skin to complete the operation. Doctors take good care of tissues and try to minimize trauma so that the recipient can recover faster. To achieve minimal surgical traces after liposuction, protecting the skin edge of the liposuction incision is also one of the key points for future wound healing and obvious scarring. Back liposuction is one of the surgeries with the largest area and the highest requirements for flatness. It is necessary to remove a layer of fat evenly to appropriately increase the tension of the skin, showing the streamline changes of the back and showing the charming style.
