40khz cavitation technology in itself means that the ultrasound causes the fat cells to vibrate so fast (high frequency) so vacuum bubbles are formed in the cell. as a consequence bipolar rf makes water molecules in the fat revolve with high speed to produce friction and shock, then triglyceride go out from fat. rf energy with 1-10m could get to 4-15mm skin depth the vacuum massages lift, mold and massage the skin deep and on the surface. the massage also increases the blood circulation, which in turn leads to the release of fat from the fat cells the mechanical roller massage works profoundly on densified connective tissues. the mechanical massage rollers enhance the skin& ir increases the oxygenation in the cells and gives a warming effect, which leads to increase in the endorphin production that relieves pain and stiffness in muscles and joints.syi
