Abstract
This chapter covers a variety of noninvasive cosmetic techniques for rejuvenating skin, removing tattoos, and improving body contour. It covers device selection; pre-, intra-, and postoperative considerations; the advantages, disadvantages, and indications of each device; previous and current devices on the market; and the mechanisms by which each of these devices work. The chapter begins by discussing laser resurfacing for multiple cosmetic disorders and laser tattoo removal, how to select the appropriate laser to treat the targeted condition, and complications to consider. It then covers body-sculpting devices such as cryolipolysis and lasers and corresponding devices, followed by magnetic resonance, radiofrequency, and ultrasound therapy for body contouring.
