Cryolipolisis is safer and more effective than Ultrasound cavitation. With one treatment, you should expect 20% of the fat cells from coolsculpting to be eliminated.
Despite solid science and personal endorsements from trusted colleagues, I've personally seen disappointing results from Ultrasound treatments on fat deposits. We tried it on patients in my office and we were not satisfied.Having said that, I believe it most important that you select a physician who you can trust to advise you on your best approach. That individual should have the broadest familiarity with all of your options, so that you don't end up simply being steered to the device that they own. Full informed consent requires your doctor to have an intimate familiarity with all of the choices available to you, including surgical techniques.
