Traditional liposuction requires an invasive procedure to remove fat from areas such as the abdomen, thighs, neck, and arms. Ultrasonic cavitation uses low-frequency sound waves to burst fat cells, transforming their contents into free fatty acids that are naturally disposed of by the lymphatic system. This process may result in lost inches on the areas treated.

How does ultrasonic cavitation work?

Ultrasonic cavitation is performed with noninvasive machines that target specific body areas with low-frequency sound waves (they are what put the “ultrasonic” in “ultrasonic cavitation”) and, in some cases, light suction.

This process heats and vibrates the layer of fat cells below the skin’s surface. The pressure eventually causes the fat cells to liquefy and release their contents into the bloodstream. Proponents of the procedure believe that the body is then able to process these fatty acids through its proverbial waste-disposal plant: the lymphatic system.

What kind of results can I expect?

Results can vary greatly from patient to patient. However, most proponents of ultrasonic cavitation claim that you’ll see: 

• Tightened skin and reduced cellulite (due to the production of new collagen and elastin fibers)
• Reduced circumference in the treated area (due to fat-cell release)
• An overall contoured appearance (due to a combination of the benefits listed above)

 How many treatments do I need and how often should I be treated to see results?

Although most practices that offer ultrasonic cavitation claim you’ll see results after the first session, they also caution that between 8 and 12 sessions are needed for optimum results. The exact number of treatments needed will vary due to factors such as age, weight, and the area being treated.

Is this procedure invasive?

No.

Is there any downtime?

No.

What are the different types of machines used for ultrasonic cavitation? Are there major differences between them?

“Ultrasonic cavitation” is a catchall term for noninvasive liposuction that works through low-frequency sound waves. Different spas and doctor’s offices use different devices to perform their procedures. Though similar, the machines can differ when it comes to the precise frequency and concentration of the sound waves. Some commonly used machine brands are Liposonix, VASER, and Cavi-Lipo.

How long do results last?

Ultrasonic cavitation does not destroy fat cells; rather, it empties them of their contents, which means the cells are capable of storing fat again. A balanced diet is the only way to ensure lasting results. Those who take in more calories than they burn will see their improvement start to decrease over time.
