With so many non-invasive body sculpting treatments available, it can be hard to know which technology is right for your goals. Two of the most popular methods—ultrasonic cavitation and cryolipolysis (fat freezing)—promise to reduce stubborn fat without surgery, but they work in very different ways.
Whether you're a spa owner deciding which machine to invest in or a client trying to choose your next treatment, here's a clear breakdown of how these two technologies compare:
How They Work
Ultrasonic Cavitation:
This method uses low-frequency ultrasound waves to break down fat cells beneath the skin. The disrupted fat cells are then processed by the body’s lymphatic system and naturally eliminated.
Cryolipolysis:
Also known as “fat freezing,” this treatment works by applying controlled cooling to targeted areas, freezing fat cells without damaging surrounding tissue. The frozen cells die off and are eliminated through the body's natural processes over time.
Treatment Sensation
Cavitation:
Most users describe cavitation as a warm, relaxing treatment with a mild buzzing sound in the ears. There’s little to no discomfort during or after the session.
Cryolipolysis:
During cryolipolysis, you may feel intense cold, tugging, or numbness in the treated area. After the session, the skin might be red or feel tender for a few days.
Results Timeline
Cavitation:
Results can begin to show after just 2–3 sessions, with more noticeable improvements after a full treatment series (typically 6–10 sessions).
Cryolipolysis:
It usually takes 3–4 weeks to start seeing changes, with full results appearing after 2–3 months. Often, only 1–3 treatments per area are needed.
Ideal Candidates
Cavitation:
Best for clients looking to slim down areas with soft fat, improve skin tone, and reduce mild cellulite. It’s also great for people who want gradual, gentle changes.
Cryolipolysis:
Ideal for people with distinct pockets of fat that don’t respond to diet and exercise—especially on the abdomen, love handles, or thighs.
Skin Tightening Benefits
Cavitation:
Often combined with radio frequency, cavitation machines also stimulate collagen production, offering skin tightening benefits in addition to fat reduction.
Cryolipolysis:
This method strictly targets fat cells and doesn’t offer any skin firming effects. In fact, some users may need RF treatments afterward to improve skin laxity.
Final Thoughts
Both cavitation and cryolipolysis are effective, non-invasive fat reduction methods—but your ideal choice depends on your body goals, timeline, and comfort preferences.
Want fast, flexible, and relaxing treatments with added skin benefits? Cavitation is the way to go.
Looking to target a specific fat bulge with fewer sessions and don’t mind waiting for results? Cryolipolysis could be your match.
