Cryolipolysis is a medical treatment used to destroy fat cells. Its principle relies on controlled cooling to near sub-zero temperatures for non-invasive localized reduction of fat deposits in order to reshape body contours. The exposure to cooling is set so that it causes cell death of subcutaneous fat tissue without apparent damage to the overlying skin. The procedure is billed as a nonsurgical alternative to liposuction. “Cryolipolysis” is a portmanteau of “cryogenic” and “lipolysis.” Generically the process can also be known as “Fat Freezing”. Specific treatments are using medical devices called CoolSculpting, a US registred trademark, owned by Zeltiq Aesthetics, Inc.. In Europe cryolipolysis machines are available in aesthetic clinics and spas.
