A.Emsculpt is a muscle building treatment, in addition it reduces superficial abdominal fat. It is not considered a skin tightening technology, though with increased muscle mass there will be some improvement as the newmuscle takes up some of the slack in the skin. We recommend other radiofrequency skin tightening devices such as Venus Legacy for post partum moms. Emsculpt is quite effective at improving diastasis recti after pregnancy (the widening of the connective tissue between the abdominal muscles.) Congratulations on the new addition to your family, much good health, love, and happiness. Good luck and be well.
