Controllable negative pressure attraction: skin tissue is attracted by negative pressure into the place between
two electrodes;inhalational tissue can be controlled accurately.Simple operation: user-friendly man-machine
conversation interface makesoperation clearer more accurate. Two big systems: Automatic control of energy
in treated areathrough digital and micro-control system .

Radio Frequency: energy is transmitted to the place
between two electrodes; the current permeates target tissue and generate heat.
