1) It can change the capacity and movement of every cell with precise massage function which is named as cells massage.
2) It can stimulate and adjust the cytomembrane, increase the permeability of epidermis, its thermal, physical and chemical effects can rise the temperature in deep skin by 

0.5-1°C, promote skin to absorb essences, accelerate metabolism and reinforce the regenerative course of tissue
3) Ultrasonic can also decompose waste surrounding fat, consume energy, repair lymph and capillary vessels with weight losing and figure sculpting functions.  

1) It can form a weak electric field between skin surface and germinal layer, temporarily break the skin barrier layer, remove dirt from pores with the principle of [Opposites Attract] and conduct essences of different functions (such as acne removing, moisturizing, whitening and wrinkles resisting) into deep skin with the principle of [homogeneous repellent]. Replenish effective ingredients into skin which may accumulate surrounding skin cells as [ion cluster], promote cells to constantly absorb essences with the absorbent concentration several and dozens times of higher than extending or oral take.
