Ultrasonic cavitation relies on ultrasound technology to break apart fat cells.

Ultrasound waves are sent deep into the layers of your skin, causing a disruptive vibration. Fat cells then break apart from each other and are dislodged from your dermal layers.

After a few days, the fat cells are absorbed by your lymphatic system and drained as waste from your body.

It’s difficult to tell how effective this treatment is, but recent research is promising.

A small 2019 studyTrusted Source tested the effectiveness of ultrasonic cavitation for 50 women who were considered medically overweight.

Half of the women simply followed a low-calorie diet, while the other half had the low-calorie diet with radiofrequency and ultrasound body contouring procedures.

After 5 weeks, the women who had been given ultrasonic cavitation showed a reduction in body fat mass. Interestingly, they didn’t lose more weight than the other group — they simply lost body fat.

Another small studyTrusted Source done much earlier in 2007 followed 30 individuals who were all given ultrasonic cavitation body contouring treatment.

Participants all saw a reduction in body fat mass after three treatments. The treated body fat area was reduced in size by one to three centimeters at the conclusion of the study.
