How long does the coolsculpting last on your body, does the fat come back?

Good question!  CoolSculpting causes your fat cells to undergo a natural process of cell death after exposure to cold.  In other words, the cells die and you will not, as an adult make new fat cells to replace them. If you gain weight after CoolSculpting, you will store fat evenly in the remaining fat cells in your body.  The area that was treated with CoolSculpting will still proportionally contain fewer fat cells.

as long as your weight is steady, you can expect the results of CoolSculpting to last very long.

Coolsculpting permanently destroys up to 20% of the fat cells within the treated area. However, you will need to maintain a healthy weight to maintain results. For best results with Coolsculpting, I recommend a combination approach. I recommend adding radiofrequency treatments like Vanquish, Venus Legacy, Exilis Ultra for skin tightening and with Z wave/Cellutone for skin smoothing. VASER with ThermiRF is a great alternative.
