The answer will vary with each individual, depending on how much padding (fat) you start with. Two fancy terms, LIPOLYSIS (fat destruction) and APOPTOSIS (cell death) are the keys to understanding results. EMsculpt, while causing muscle hypertrophy (building), also implements lipolysis and apoptosis. While the effects of hypertrophy can be seen quickly (as little as 2-3 weeks), lipolysis and apoptosis take much longer because the destroyed cells have to be "washed out" through your system and can take several months, depending on how much fat was covering the muscle in the first place. I hope this helps with understanding a little bit about the physiology of EMsculpt
