Will a percentage of the fat cells that are eliminated after Coolsulpting return?

Cryolipolysis is the non-invasive cooling of fat cells to induce lipolysis without damage to other tissues or structures and no surgery or downtime. This precise cooling induces fat cell apoptosis followed by natural dissolution of the cell. It is the world's #1 non-invasive fat-reduction procedure with over 3 million treatments performed worldwide.
When fat cells are exposed to cold temperatures they become terminally injured and gradually die (cellular apoptosis). The cells die within the first 2-3 days and begin to collapse. Macrophages digest and consume the dead fat cells and lipids within the cells. This debris is cleared through the lymphatic system.
Fat cell numbers are fairly set at puberty (new fat cells can only be generated if they reach a “critical” size). When you lose or gain weight, the volume of fat cells change but the number of fat cells remain the same. Only possible biological instance of growing new fat cells is during pregnancy and in cases of extreme obesity. CoolSculpting eliminates on average 20-25% of fat cells treated.
Like a cut, what we’re doing is inducing that natural cellular response. Body sends digestive cells eating away at those cells (apoptosis). CoolSculpting "cuts" the fat cells, the macrophages are sent in and clean out those damaged fat cells and they're metabolized.
I hope that helps! Let us know if you have any further questions. 

The fat cells that are treated with CoolSculpting will be removed from the body for good after your appointment. Only about 25 to 45 percent of fat cells in the target area will die off after treatment, but results vary.
