Great Question! Unfortunately, cold packs are not an effective way of killing fat cells, you may end up damaging your skin. CoolSculpting uses controlled cooling (-12C) for a specific period of time to crystalize fat cells. Cold packs simply cannot get to this targeted temperature. Best of luck!
If only the death of unwanted fat cells were that cost effect but unfortunately it's a little more complicated than it seems. You're on the right page with the science of freezing the fat cells, however you're running the risk of exposure such as frost bite when there is direct contact between the skin and freezing temperatures. The CoolSculpting adapters are specially designed to use a combination of suction and freezing to target the underlying unwanted fat cells without any damage to the skin. It's best to seek an in-person consultation with a Board Certified Surgeon in your area, that specializes in CoolSculpting, to evaluate the areas of concern and determine the best game plan tailored to you. Good luck!
