Cavitation is a non-invasive technique which allowsto efficaciously treat cellulite without resorting tosurgery. Applied both in aesthetics and in medicalfield, cavitation uses ultrasonic waves at low frequencyto get the fat cells breakage. The ultrasonicwaves are propagated into tissues by generatingboth expansion waves (negative pressure) and compressionwaves (positive pressure). This pressuredifference creates some gas bubbles insight the liquids. Successively, the external pressure to bubblesincreases by causing the fat cells breakdown. Fatswill be immediately metabolized by body disposalsystem, by passing through lymph nodes of interstitialliquid. Cavitation affects fat cells only since other tissuescells (such as muscles, vessels etc.) are more resistantand therefore they don’t suffer of any damagefrom bubble implosion.
