Overview of lasers used in dermatology

Abstract

Before one can efficiently utilize laser technology, one must first have a basic understanding of laser-tissue interactions. This chapter aims to provide a quick reference outlining the currently available laser devices and their associated indications. A brief overview of the physical properties of the major cutaneous chromophores including thermal relaxation times and absorption spectra are also discussed. It is important to note that as laser technology evolves, new laser devices are being developed and indications for use are constantly expanding; therefore, this chapter may serve as a guide to the currently used devices and common indications, but should not be considered comprehensive.
