Both Exilis and Trusculpt solutions are radiofrequency technologies which means that skin is tightened simultaneously at the treatment site. A cool sculpt option is cool, and will not tighten skin. Small areas such as most upper arms, under the chin, armpit, knees can be treated just with the truSculpt small handpiece. The protocol is two treatments, spaced 6 weeks apart. Final results can take up to 12 weeks as the body metabolizes and excretes the destroyed fat cells. Larger areas are treated with the large truSculpt handpiece and require only one treatment. This also takes up to 12 weeks for the final results to materialize. Exilis Ultra can be set to just tighten skin, or to blast fat AND tighten skin. For larger areas, we have found that combining truSculpt with Exilis leads to a smoother, more uniform result. A typical Exilis protocol is once a week for 4 weeks. Results can take 6-12 weeks to appreciate. Exilis will not destroy as much adipose tissue as truSculpt, but for many people and in many areas, this is all that is required. The standard protocol for larger areas such as abdomen, bra or back fat, flanks or saddlebags, is one truSculpt treatment, followed by 4 Exilis treatments once a week, starting 2 weeks after the initial truSculpt treatment.
