CoolSculpting by Zeltiq uses a patented process called cryolipolysis(TM) to lower the temperature of fat cells sufficiently to freeze them, triggering apoptosis (cell death). However, the temperature is not sufficiently low to freeze water, skin, or other tissue. The skin may be numbed from the cooling process and will probably redden slightly for a short time, but the effect is not permanent. There is a gel pad placed between the skin and the application to further protect the skin. In some delicate areas, an anti-freeze wipe is also rubbed on the skin. Don’t worry, you won’t get frostbite from CoolSculpting! Any side effects, such as redness, soreness, bruising, or tingling, usually resolve within hours to days. Please see a board-certified dermatologist to find out how CoolSculpting can help you.
