Negative pressure liposuction: this is the earliest mechanical liposuction method, which uses negative pressure, specific straws, suction heads and appropriate anesthesia to suck out local fat.

Ultrasonic liposuction: Facial liposuction and face-lifting is a relatively safe method at present, which uses ultrasonic energy to selectively destroy fat cells and then liposuction adipose tissue through negative pressure, which is divided into in vivo ultrasound and in vitro ultrasound.

Electronic liposuction: the thermal effect generated by a high-frequency electric field with a certain intensity heats adipose tissue, which leads to the rupture of adipose cells and is beneficial to liposuction.

* * * vibration facial liposuction and face-lifting method: Based on the principle of * * * vibration, the sucker, under the control of computer fuzzy program, generates mechanical * * * vibration waves with the same natural frequency as fat cells, which selectively destroys fat cells, facilitates suction and can effectively protect nerves and blood vessels.
