With the improvement and development of related technologies, liposuction is no longer just to remove adipose tissue, but to combine the technique of injection transplantation of fat particles with superficial liposuction to remove the high and replenish the low, and shape the ideal human contour, so liposuction has also become liposuction or human sculpture. Liposuction, called liposuction in full, is a surgical method that uses negative pressure suction and/or physical and chemical means such as ultrasonic wave and high-frequency electric field to remove pre-treated or untreated subcutaneous fat accumulated locally in human body through small skin incision (generally 0.5- 1cm) or puncture hole, and combines with technologies such as fat particle injection and transplantation to improve appearance or appearance.
