Abstract

Low-level laser or light therapy (LLLT) was used to accelerate wound healing without the use of thermal effects in the early days. Although the exact mechanism of LLLT is still unclear, it has been recognized as a photobiomodulation process. Today, LLLT is being credited as a non-invasive treatment modality, and in particular, being widely applied in the field of dermatology. In this review, we summarize the basic principles and clinical applications of LLLT to provide an up-to-date guidance on its practical and safe uses. Further studies are needed to elucidate the mechanism of action of LLLT in various indications, and to determine the wavelength and dose for optimal clinical use.
