How does 40k Cavitation work?wave fat system With collective strong sound wave head, strong sound wave of 40KHZ vibrates fat cells at top speed and producenumerous vacuum air pockets inside and outside the fat cells, robustly impact fat cells to generate introverted blast anddisintegrate triglyceride into glycerol and free fatty acids.Then RF waves at frequencyof 1M HZ isused for exhausting theintegrated glycerol and free fatty acids through hepatoenteral circulation. Finally, vacuum RF and energy electrode are used forpositioning and tightening fat. In physics, it is known as "cavitation". Micropore introverted blast inside and outside cell maylead to enhanced molecular motion and a higher energy level and this will finally cause fat cell rupture and thereby achievetheeffectsof body building and losing weight.Functions:1. Slimming and fat diolving2. Tighten skin,anti-aging3. Improve blood circulation and metabolism4. Smooth scar and wrinkles5. Smooth striae gravidarum6. Enhance fibroblast elastic tiue7.
