painless treatment focus rf energy at the correct position,compared to other radio frequency technology .it uses low energy and high frequency,safe and effective. aim at the skin surface and deep location,using a complex method to control the different currents and energy, direct access to the different skin layer. does not cause uneven skin. selectively targeting fatty tissue,to avoid heating other fat,to achieve the fastest treatment effect the entire process is completed without the need of surgery and anesthesia. with the most useful 40khz ultrasonic cavitation system.without side effects and the risk of gaining the weight back, the results are rather obvious. does not affect the normal work and life..syi
