SculpSure is extremely safe. The few risks are: redness, swelling, and discomfort at the treatment site, all of which have only been experienced temporarily. All lasers use heat to provide their results, and heat is known to cause tissues to tighten, much in the way heat causes shrink wrap to tighten. So SculpSure, being a laser, must provide some tightening effect. However, that tightening has never been quanitified in a study, and may be very slight. If you are looking for a non-invasive skin tightening treatment, there are other technologies you should look into, such as Exillis, Thermage, and Ulthera. The initial FDA clinical trials for SculpSure did not include scars. Factors of unknown safety are listed as unsafe in most guidelines for new technologies, until proven safe. However, we now know through anecdotal evidence of many physicians using SculpSure, that treatment over and around scars can be safe and effective. The real concern here is the physical structuring of the scar tissue, which the skilled hands of a physician can discern. Some scar tissues are fine to treat directly over, and others need to be planned around, so that the SculpSure treatment panels deliver energy directly around but not on top of.
