How Fat Freezing Works The Fat freezing technology or cryolipolysis is designed to make you look your best Simple, apply the Fat Freezer over your problem areas (Stomach, thighs, waist back or bottom) and select a 30 or 60 minute session. The cooling process targets problematic areas in the body. The Fat Freezer can be used for both men and women. Of course you should not expect to see results all at once. Although this is not a weight lost system, we encourage Fat Freezer users to eat right and exercise daily
