Since it was cleared by the FDA in 2010, CoolSculpting has been used in more than 2.5 million treatments worldwide. And we have safely performed thousands of CoolSculpting treatments at Greenwich Medical Spa. CoolSculpting’s targeted cooling ensures that unwanted fat cells are frozen, but other tissues are not affected in the process. The body naturally eliminates the damaged fat cells over time, so all you will notice is that your double chin becomes smaller. Other than the potential of initial swelling and numbness, there are no long- or short-term side effects of CoolSculpting.
