Can cold packs do what CoolSculpting does for the killing of fat cells?

Since CoolSculpting uses cold temperatures to essentially freeze away unwanted fat, it makes sense to wonder whether simply applying ice packs at home would achieve the same results. Unfortunately, it just doesn't work that way. The temperatures applied during CoolSculpting treatments must be very precisely controlled to target fat cells specifically without damaging the surrounding tissue.
 

It would be wonderful if ice packs could freeze away our fat, however an ice pack will only freeze and damage the skin.Coolsculpting reaches a targeted temperature and the temperature is held at that point for enough time to eliminate the fat cell, but not to harm other tissues.All the best to you,Dr. Nancy de Kleer

Cold packs are cold enough to freeze and damage the skin. CoolSculpting is not. CoolSculpting is FDA-approved to kill fat cells with cryolipolysis — a technique patented by Zeltiq. Its cooling temperatures are sufficient to send fat cells into a slow-death cycle (apotosis), but not sufficient to freeze the skin, organs, or other tissues. 
The CoolSculpting machine also has monitors to alert the physician if the treated area is becoming too cold. Cold packs cannot be monitored, would burn the skin and cause frostbite, if applied too long, and would be unlikely to kill any fat. Please find a board-certified dermatologist to administer your CoolSculpting body-contouring procedure to get the most beautiful and uniform results.
