01
What it is
Ultrasound Cavitation applies focused low-frequency sound energy to subcutaneous tissue. At sufficient intensity, the alternating pressure phases of the wave cause microbubbles to form inside adipocyte fluid; those bubbles oscillate and ultimately implode in a process called cavitation, rupturing the fat-cell membrane. The released triglycerides enter the interstitial space, where the lymphatic system progressively transports and metabolizes them.
It is a non-thermal, non-invasive process: no heating, no incisions, and the surrounding vascular, neural, and connective tissue is mechanically unaffected.

How it works in tissue
The cellular mechanism is selective: adipocytes, being large, lipid-filled, and less mechanically resilient than surrounding structures, are preferentially disrupted at the frequencies and intensities used in aesthetic cavitation. Fibroblasts, keratinocytes, and vascular endothelium tolerate the energy intact.
Following a session, triglyceride clearance through the lymphatic system takes time — which is why protocols space treatments across weeks rather than days, and why lymphatic support (manual drainage or vacuum massage) is routinely combined to assist clearance.

Where it earns its place
Cavitation pairs naturally with radiofrequency and vacuum massage in a single visit: fat disruption followed by circulatory stimulation and skin tightening in one protocol, one appointment, one revenue event. It appeals to patients who are at or near a healthy weight but presenting with localized deposits — a common consultation scenario — and is well-suited to series programs with measurable circumference tracking across visits.
