The temperatures used in Coolsculpting have been rigorously evaluated to maximize fat reduction while maintaining a substantial safety margin. Continual temperature monitoring is utilized during the treatment to assure safety. During the treatment the skin reaches about -11 degrees Celsius with the superficial fat getting to about -8 or -9 degrees Celsius and the deeper fat reaching approximately 0 to +4 degrees Celsius. The temperature of the fat is the critical aspect of CoolSculpting to achieve cryolipolysis or fat cell destruction. The special CoolSculpting wipes used on treatment area lowers the freezing point of the skin and allows the skin to withstand the colder temperatures.
