Abstract

|
|
Intense pulsed light (IPL) is a high-intensity pulsed light source emitting polychromatic, non-coherent, and defocused light with a broad wavelength spectrum. However, IPL can similarly work as a conventional laser with the help of variable cut-off filters. It enables selective destruction of target chromophores based upon the theory of selective photothermolysis. Clinicians can combine variable factors including wavelengths, pulse durations, and fluences in IPL systems, which allow great versatility in treating wide ranges of dermatologic diseases and flexibility in optimizing individual treatment parameters according to different skin types or indications. These properties are of great advantage for skilled and experienced clinicians but can be a source of unwanted serious adverse effects for untrained ones at the same time. Therefore, we summarized the basic principles and clinical application of IPL devices to provide the practical guidance. In addition, critical diagnostics, a great deal of experience, and a thorough knowledge of skin pathology and physiology are required for an effective and safe IPL treatment
