FatFreeze (Cryolipolysis) isolates and permanently destroys fat cells in the area of treatment by lowering the temperature to -11 degrees Celsius for 45 minutes. The body then eliminates the fat cells as waste. While many patients report seeing a change in the first week, full results are seen in 12-16 weeks. Typically only one session is needed to achieve the desired results. If additional sessions are needed in the same area, they can be performed after 8 weeks.
