title: Laser: when is it helpful, unequivocal, or simply a marketing tool.
abstract: Since lasers were first used for dermatologic applications in the early 1960s, they have continued to evolve as part of standard dermatologic practice. Initially, lasers were received enthusiastically but have since waxed and waned in popularity. I review the history of lasers and the differences between the common clinically applicable laser systems. Lasers have added a substantial dimension to our practice but have also been fraught with overuse. In an era of cost containment and health care reform, we need to consider the appropriate part lasers should play in dermatologic practice.
