Vague and inexact word usage can complicate conversations about cutaneous energy devices, especially novel technologies.To identify some areas in which descriptions of lasers, lights, and energy devices can be improved.Ambiguities in descriptions of energy devices are addressed by suggesting sets of modifiers that are precise, accurate, simple, and mutually exclusive.Terms are proposed for distinguishing between devices that induce skin injuries of different depths. Additionally, descriptors are suggested for fractional treatments, fat melting, and cellulite reduction. Finally, we propose a scheme for clearly naming the underlying technology associated with any cutaneous energy device.Novel devices yet to be invented may not fit into the designations proposed and may require additional categories.Simple changes in word usage may facilitate rapid and accurate communication regarding lasers, lights, and other energy devices.
