Cavitation
“Cavitation” is used in aesthetic marketing for certain ultrasound body-contouring treatments. It describes a technology category, not one standardized machine, setting or guaranteed result.
How ultrasound relates to body contouring
Some therapeutic ultrasound devices deliver energy through the skin to affect underlying fat and may reduce the circumference of a treated area. Results and authorized treatment sites depend on the exact device. Evidence for one ultrasound system cannot be transferred automatically to every machine called “cavitation.”
Contouring
A localized appearance goal, assessed for a specific device and person.
Weight loss
Not the purpose of non-invasive body contouring, which does not treat obesity or provide the health benefits of weight loss.
Benefits have limits, and risks matter
Outcomes may be temporary or less noticeable than expected. “Non-invasive” does not mean painless or risk-free. Ultrasound body-contouring risks can include discomfort, redness, swelling, blisters, burns and nerve injury. Open wounds, compromised skin, active implanted devices and metal beneath the skin are among reasons ultrasound treatment may be inappropriate. This is not a complete screening list.

Questions to ask before treatment or equipment purchase
- What is the exact manufacturer and model?
- What intended use and body sites appear in its current instructions?
- Can the provider show the device-specific evidence and applicable U.S. marketing authorization?
- What training, screening and aftercare does the manufacturer require?
- What is a realistic benefit, how is it assessed, and what happens if there is a complication?
Do not infer authorization from a general technology description, supplier logo or another model’s documentation. This article does not certify any BellaSkin machine’s regulatory status or suitability for an individual.
Frequently asked questions
Is cavitation always painless?
No. Comfort varies, and pain or an unexpected reaction needs attention rather than a promise that it is normal.
How many sessions or what settings should be used?
There is no universal answer. Follow the exact device’s instructions and an appropriately qualified provider’s assessment. This educational guide does not supply operating parameters.
Should it automatically be combined with radiofrequency or massage?
No. A combination requires its own suitability review; simply adding treatments is not evidence of better results.
