Cryolipolysis is a medical treatment used to destroy fat cells. Its principle relies on controlled cooling to near 4° Celsius (approx. 39° Fahrenheit) for the 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”. The process is also known as “fat freezing”.
Evidence supports its effectiveness at three to four months.
Method of actions:
Lipolysis procedures attempt to “dissolve” fat cells by nonsurgical means. Based on the premise that fat cells are more easily damaged by cooling than skin cells, Cryolipolysis was developed to apply low temperatures to tissue via thermal conduction. It appears that fatty tissue that is cooled below body temperature but above freezing undergoes localized cell death followed by a local inflammatory response, a local panniculitis, that gradually over the course of several months results in a reduction of the fatty tissue layer. When exposed to extreme cold, the body’s usual response is to restrict circulation to keep the core of the body at the correct temperature. Cryolipolysis makes use of a powerful vacuum which adds to the inflammatory response by drawing blood up to the surface layers of the skin.
Treatment time for general use/application is 45–60 minutes per site.
