CoolSculpting by Zeltiq uses cold energy to permanently destroy fat cells. The CoolSculpting machine works by pulling your fat bulge into a device that has two cooling plates. The fat is held by a strong vacuum. The cooling plates are activated to the specific temperature where fat cells are vulnerable and die, and your skin, nerves, blood vessels, etc are fine. This process takes an hour per area. Multiple areas can be done at one time in some cases.
There is no downtime for this treatment. Minor side effects can be expected such as bruising
