I have read reviews that coolsculpting is temporary. Is this true? Will new fat cells replace the frozen ones?

the results of coolsculpting are permanent however, there are still fat cells there that remain and those can enlarge if you do not keep your normal diet / exercise.  Best, Dr. Emer.

Don't believe all the reviews that you read. The fact is that as long as you maintain a healthy diet and an active lifestyle the results of the CoolSculpting treatment can be permanent. Naturally, if you gain weight after the procedure then your remaining fat cells may enlarge or you may form new fat cells which can then negate your results. Hope this clears things up for you.
