CoolSculpting is the brand name for a fat-freezing method that aims to get rid of stubborn fat in certain parts of your body. The method is called cryolipolysis. The U.S. Food and Drug Adminstration approved it in 2010.
Scientists came up with the idea for cryolipolysis by studying what happens to fat during frostbite. Fat freezes at a higher temperature than skin. The cryolipolysis device cools your fat to a temperature that destroys it while leaving your skin and other tissues unharmed.https://www.webmd.com/beauty/coolsculpting#1
