Their flagship product, CoolSculpting, is an FDA-cleared procedure that targets and eliminates stubborn fat in specific areas of the body. The treatment is based on the principle that fat cells undergo programmed cell death when exposed to cool temperatures. Zeltiq went public in 2011 and also offers CoolSculpting Elite, a non-invasive fat reduction treatment, and CoolTone, a body contouring treatment that strengthens and tones muscles.
