title: Basics of lasers in dermatology.
abstract: Lasers have become a critical part of the dermatologist's armamentarium for modulating cutaneous biology, both in treating skin disorders and providing tangible cosmetic alterations to the skin. Although modern lasers are relatively straightforward to use, they are powerful tools that are capable of considerable damage when used incorrectly. Developing an understanding of how these lasers function is essential to their safe and responsible use. This article will discuss the fundamental concepts of lasers in dermatology and the cutaneous interactions they cause.
