Hi and thank you for your question!
Coolsculpting reduces subqutaneous fat over 3 months time after each treatment, often 2 treatments are needed for ideal result. It certainly will not create loose skin and if anything, the inflammation that occurs can potentially result in some tightening, however, we say this is icing on the cake, as it is a fat reduction device and not a skin tightening device. The exception is the submental area, upper neck/ below the chin, which does have an FDA approval for skin tightening, as well as fat reduction. That said, since we have our patients now using Alastin's Transform Body Cream along with their coolsculpting treatments, we are seeing much more skin tightening effects from the treatments, in all areas of the body, as well as quicker and more dramatic results! EmSculpt and its newest version, which we have, called Cooltone, are for building and strengthening muscles, and not for fat reduction or for skin tightening. While they will pair wonderfully together (Coosculpt and Cooltone) they have two different applications. Definitely have some consults done with very experienced practices, as this can make a big difference in treatment results.
Best,
Dr. Grant Stevens
