Comparison
Cavitation vs cryolipolysis: what's the difference?
Both target localised fat without surgery, using opposite physical principles. A factual comparison — including where cryolipolysis has stronger evidence.
In short
Cavitation uses low-frequency ultrasound (a mechanical effect); cryolipolysis uses controlled cold (fat cells being more sensitive to cold than other cells). Cryolipolysis has a larger clinical literature; cavitation is delivered in shorter, more frequent sessions and combines easily with radiofrequency.
| Criterion | Cavitation | Cryolipolysis |
|---|---|---|
| Energy | Low-frequency ultrasound | Controlled cold, often with suction |
| Principle | Mechanical effect on adipose tissue | Adipocytes are more sensitive to cold [1] |
| Schedule | Course of close sessions | One or a few sessions weeks apart |
| Sensations | Buzzing, mild warmth | Intense cold at first, temporary numbness |
| Reported side effects | Temporary redness | Redness, bruising, temporary numbness; rare delayed pain [1] |
| Clinical literature | More heterogeneous across devices | Larger, including controlled trials [1] |
Which to choose?
There is no universal answer. Both suit people close to their ideal weight with localised fat. The choice depends on the area, tolerance to cold or heat, the session schedule and the goal — if skin firmness matters as much as shape, combining cavitation and radiofrequency may be relevant. For clinics, room occupancy also matters: a multi-area device such as AdipoXtrem treats several areas in a 30 to 35 minutes depending on the programme session.
