A novel self-induced, non-ablative, threedimensional fractional FRAC3® method for skin treatments is described. The method utilizes the short
pulse duration and high peak power density of Accelera mode, Nd:YAG laser pulses. The Accelera Nd:YAG pulses produce a three-dimensional fractional pattern in the epidermis and dermis, with damage islands that are predominantly located at the sites of skin imperfections. In-vivo thermal measurements of the skin surface and in-vitro measurements of skin crosssections, following illumination with Accelera Nd:YAG pulses are presented. The measurements demonstrate the emergence of isolated »fractional« hot islands within the skin. Clinical results following Accelera Nd:YAG laser treatments are also presented. The FRAC3® method offers practitioners another dimension of safety and self-regulating efficacy in nonablative treatments such as skin rejuvenation and hair removal.
