The likeness in names might lead you to believe that these devices are comparable to CoolSculpting. In reality, they are laser devices, which shrink fat cells with temporary results. CoolSculpting, on the other hand, kills the fat cells for permanent results. While you might notice an improvement from laser fat reduction, it will not last. CoolSculpting has been proven effective through several Harvard studies, and it is FDA cleared for noninvasively reducing fat.
