The age group for ultrasonic face-lifting is around 25-50 years old. Ultrasound face-lifting is a method of face-lifting using ultrasonic liposuction. As a new technology, ultrasonic liposuction has been used in clinical practice. Liposuction is a type of suction fat removal. It can not only slim down the face, but can also be used on people with various obesity and localized fat accumulation to improve their body shape. This method has less trauma, less bleeding, faster recovery, less ecchymosis and no loss of sensation, which increases the safety of ultrasonic liposuction.
