Fat reduction resulting from a CoolMini treatment is permanent.  Once fat cells are frozen, they are eliminated by your body and they do not come back.  In order to maintain the results from your treatment, it is important that you do not gain weight afterwards.  Although the fat cells targeted by the CoolMini treatment are gone for good, the treatment targets only 20-25% of the cells in the area while the rest of your fat cells remain.  The fat cells that remain can grow larger with weight gain and, as a result, it is possible for the treated area to increase in size as a result.  This is true of any permanent fat reduction procedure whether it is Liposuction, Laser Liposuction, CoolSculpting, Sculpsure, or any other treatment that eliminates a portion of your fat cells.  The bottom line is that results from a CoolMini treatment are permanent as long as you maintain a steady weight (or lose weight) after your treatment.
