RESUMEN
Intense pulsed light (IPL) is a high-intensity polychromatic incoherent light of a determined wavelength spectrum, fluence, and pulse duration. Clinicians can combine these variable factors of IPL for the purpose of selective destruction of target chromophores. Due to these properties, IPL has been widely used for numerous indications including hair removal and treatment of vascular or pigmented lesions. For skilled and experienced clinicians, IPL is a great treatment modality; however it can be a source of serious adverse effects when performed by untrained clinicians. Thus, to promote the proper and safe use of IPL, we summarized the origin, history, basic principles, and clinical application of IPL and discussed qualification factors needed for clinicians who use IPL.
