From the Research
Cryolipolysis (CoolSculpting) is more effective at fat reduction compared to ultrasonic cavitation, with studies showing a significant reduction in fat layer thickness and abdominal circumference. Cryolipolysis works by freezing fat cells, causing them to crystallize and die, with the body naturally eliminating them over 2-3 months 1, 2. A typical treatment takes 35-60 minutes per area, with results becoming visible after 3 weeks and optimal results at 2-3 months. Patients typically need 1-3 sessions spaced 4-8 weeks apart.
Key Points to Consider
- Cryolipolysis can reduce fat in the treated area by 20-25% after a complete treatment course, while ultrasound cavitation typically achieves 2-4 cm circumference reduction 3.
- Ultrasound cavitation uses sound waves to create bubbles in fat cells that burst and release fat, which is then metabolized by the body, but requires more frequent sessions (8-12 treatments, typically weekly) and produces more modest results 3.
- A recent study published in 2025 found that cryolipolysis is a safe and effective method for noninvasive focal subcutaneous fat reduction, with a low risk of adverse events 4.
Comparison of Treatments
- Cryolipolysis: more effective for targeted fat reduction, with significant reduction in fat layer thickness and abdominal circumference 1, 2.
- Ultrasonic Cavitation: better for those seeking more gradual changes with no downtime, but requires more frequent sessions and produces more modest results 3.
Recommendations
- Choose cryolipolysis for targeted fat reduction, especially for areas with significant fat deposits, as it has been shown to be more effective in reducing fat layer thickness and abdominal circumference 1, 2.
- Consider ultrasonic cavitation for more gradual changes with no downtime, but be aware of the need for more frequent sessions and potentially more modest results 3.
