Can fat cells regenerate?

Sounds like you have experienced more fat loss than you wanted. The answer to the first question is no.  All these methods, CoolSculpting, SculpSure, Liposuction, Smartlipo work because they destroy fat cells.  Those cells are not coming back, they are gone. Other fat cells can enlarge, so after a body contouring procedure it is good to maintain but not gain weight as the extra calories can go to fat storage in the remaining cells.Cells that were frozen from CoolSculpting are destroyed and  gone. No regeneration is possible.To restore contour to areas of body fat that were removed and left a contour deformity, fat transfer must be done.  With these techniques, fat is harvested from where it is in excess, washed, prepared, and carefully re-injected to the desired area. Not all this fat will get a new blood supply and live, so sometimes a second procedure is necessary for full correction.

Thank you for your question. SculpSure is much more effective than CoolSculpting while involving a much shorter treatment. SculpSure has the capability to tighten skin and reduce 25% of body fat in the treated areas. I suggest that you move forward and consult with a board certified facial plastic surgeon.

No, once fat cells are destroyed or removed, they cannot come back!  Fat cells, or adipocytes, are derived from stem cells which stop forming during our teenage years.  That is the reason why children who grow up obese are more likely to be obese as adults- they generated more fat cells!  Once that process is complete, we have a finite number of fat cells in our body.   The reason we change size is that fat cells are designed to store fat, so they can be tiny, or grow in size by a 100-fold or more!  When we have a procedure that removes fat like liposuction, SmartLipo, or a tummy tuck, the fat cells can't come back.  Similarly procedures like Coolsculpting and SculpSure which destroy fat cells and cause them to die and be removed by the body, also are considered permanent.  However, remember that the fat cells that remain in the area or in untreated areas can still grow by 100-fold, so that is why it is important to maintain a healthy diet and weight after your fat-removing procedures!  Hope this helps and best of luck on your journey!
