Guo Jiuzhang, director of Beijing Shengjiaxin Plastic Surgery Hospital, said that arm liposuction can effectively solve the problem of poor upper arm shape. Measure the elasticity of skin before liposuction of arm. Pinch the skin thickness with your index finger and thumb and draw an outline. There is less fat in the front of the arm, so liposuction in the arm is mainly liposuction under the armpit and on the back and outside of the arm. Arm liposuction is performed under the armpit or above the elbow, and the scars of both are not obvious.
