If Coolsculpting can freeze fat away, can I do it at home with ice? More specifically on my eyelids?

Part of what makes CoolSculpting® a remarkable, non-surgical fat reduction method is that it uses controlled cooling (cryolipolysis) to eliminate fat cells while preserving surrounding tissue. Not only will applying ice cubes to your face or body prove ineffective at freezing fat, doing so can also damage your skin. Further, you mentioned that you have excess fat around your eyelids, which is not a treatment area that CoolSculpting® can address.

CoolSculpting reduces unwanted neck and body fat using the principle that the temperature needed to kill fat cells is not as cold as the temperature needed to kill skin cells. Don't use ice at home as that would be too cold, and frostbite and death of the skin cells could cause a wound that will cause not only permanent scarring, but a contraction of skin that can pull the eyelid away from the eye and cause corneal exposure damage.

Many patients have asked, "Well, if Coolsculpting gets rid of fat, why can't I just put ice on the area I want to melt away the fat?" 

Nope. It will not work like that. And we would not recommend putting ice on your eyelids to melt away upper eyelid fat. Without adequate supervision you could bring on unwanted side effects and even injury to your adjacent structures, like your eyes!

The process by which cryolipolysis induces a programed cell death is one that follows a very well structured sequence of inducing cell cycle change by manipulating the temperature of the surrounding tissue. Placing ice in a random fashion will not result in similar results.
