At the start of your treatment, you may feel a tugging sensation from the suction of the CoolSculpting device. The treatment area will grow colder and colder until it becomes temporarily numb, around 5 to 10 minutes after the session begins.
While some patients may find the cold a little odd or uncomfortable, this should soon fade as the treatment area becomes numb. At no point should CoolSculpting cause pain or serious discomfort.
