The pulsed dye laser (PDL) is a vascular laser that emits a wavelength of 585 or 595 nm in the yellow band of visible light. It is one of the early lasers used in dermatologic practice, which had a fixed short pulse width and was invented primarily to treat vascular malformations. Over the years, technology has evolved and the modern PDL machines now offer a range of selected pulse widths which offer a broad range of treatments, in keeping with the principle of selective photothermolysis which will be discussed below. Currently, this kind of laser technology successfully treats a long list of conditions in dermatologic practice, which will be highlighted in this article.
Lasers have evolved over the past five decades to become an integral part of some aesthetic and dermatological treatments. The current dermatological arena contains a plethora of lasers that can largely be categorised…
