If I keep a piece of ice under my chin, would it remove excess fat?

Thank you for your question, selenamandra. This home remedy will not remove excess fat. Kybella will. Kybella is the first and only FDA-approved injectable drug to contour and improve the jawline due to "double chin" neck fat and can provide tremendous results after a non-invasive treatment with little to no discomfort during its short recovery time. Please consult with a board certified facial plastic surgeon.Best wishes,

Most likely you would create frostbite of the skin which could lead to unsightly scarring and other issues. The trick with the cool sculpting technique is that it can cause the frostbite to occur first in the fat while sparing the skin. This is easier said than done and can cause unwanted irregularities also.

I completely understand why you are asking this question.  The problem with using ice is that it will kill your skin as well as the fat.  Furthermore, the result would be uneven.  The Coolsculpting idea works by controlling the temperature to a level that is safe for the skin, but will still kill the fat beneath it.I wish you luck!
