Do fat cells return after cool sculpting?

Hello, I was wondering if fat cells are replenished in the areas where cool sculpting has been done. I've heard that fat cells naturally die off and are replaced, so what's stopping your body from replacing the fat cells that are killed off via coolsculpting... say after a year. Currently, the Coolsculpting site says "Patients experiencing fat layer reduction show persistent results at least six months after the CoolSculpting treatment". Does that mean results are temporary?
