Light-Emitting Diodes (LEDs) in Dermatology

Light-emitting diode photobiomodulation is the newest category of nonthermal light therapies
to find its way to the dermatologic armamentarium. In this article, we briefly review
the literature on the development of this technology, its evolution within esthetic and
medical dermatology, and provide practical and technical considerations for use in various
conditions. This article also focuses on the specific cell-signaling pathways involved and
how the mechanisms at play can be put to use to treat a variety of cutaneous problems as
a stand-alone application and/or complementary treatment modality or as one of the best
photodynamic therapy light source.
