This is an excellent question. Since CoolSculpting is the only machine cleared by the FDA for cryolipolysis, it is critical you work with providers that use this advanced system. Cryolipolysis technology delivers controlled cooling to fat cells, crystalizing them so they can be eliminated naturally by the body. I would recommend asking practices if they use CoolSculpting and if you can see the device to see the brand name. You can also go to the CoolSculpting website and find a listing of practices in your area that use CoolSculpting for fat reduction. Make sure you also work with a board-certified dermatologist to ensure your procedure is both safe and successful.
