Q. I can't seem to get rid of my double chin no matter how much weight I lose. I don't want to have a facelift. I've heard that CoolSculpting could be effective. Does it work? Is it safe?

A. CoolSculpting is the trade name for cryolipolysis, which is a treatment that uses cold temperatures to destroy fat cells while avoiding frostbite to the overlying skin. It is based on a discovery that fat tissue can be damaged by cooling it to temperatures that do not harm surrounding skin, nerves, blood vessels, or muscle tissue. The procedure targets areas of fat that are resistant to diet or exercise, offering a noninvasive alternative to liposuction.
