I tried icing the fat underneath my chin for an hour and a half.

It's human nature to wonder if you can do what a machine can do when, essentially, you're just "freezing" fat. But although CoolSculpting is said to "freeze fat", it's not meant in a literal sense.Fat cells treated by CoolSculpting reach "near-freezing" temperatures, but not the same temperatures of ice. Ice applied to the skin CAN be damaging, so do-it-yourself CoolSculpting without the benefit of the science behind real CoolSculpting can be somewhat risky.Frostbite is real and it is dangerous, so put your ice cubes back in the freezer. If your skin is blistered, turns white or dark or becomes painful, do see a doctor. 

Thank you for your question. Icing an area is not the same as CoolSculpting and can be very unsafe. See your doctor if your skin changes colour. If you are interested in CoolSculpting, I would recommend that you see a board certified plastic surgeon for an in-person consultation. This way, you can explain your concerns, learn more about the procedure, and find an option that fits you best. 

Thank you for your question. Putting ice under the chin will not provide the same results Coolsculpting. The Coolsculpting technology was developed and studied for years before release to the public. There are safety mechanisms in place as well as clinic trials to prove its efficacy. Putting ice directly on skin can cause frostbite. Chances are you will be fine as long as the skin doesn't turn colors. Keep an eye on it. I hope this helps,
