When a practice has dual machines, two applicators can be applied in one session. Twelve applications with a dual CoolSculpting system would take six hours of treatment time and a couple more hours of application, removal, massaging, and rest breaks. It would not be unsafe on the body to do this many treatments, but could be uncomfortable and tiresome for the patient. In my practice we recommend a maximum of three sessions in one day, which can be done in four hours. There may be special circumstances for wanting more treatments done at one time but that is something to be discussed with your CoolSculpting provider. CoolSculpting treatment plans are customized for the individual patient and it is best to find a top provider who has experience. Practices with high volume may also have special pricing for CoolSculpting. In my Raleigh NC practice we offer patients Instant Rebates for free CoolSculpting sessions with each session purchased. This is especially helpful for patients who require multiple treatments to achieve the desired results.
