Abstract

Light-emitting diodes (LEDs) are a novel, non-thermal light modality that can be used to treat a variety of cutaneous conditions. When tissue is exposed to low-intensity light it triggers intracellular reactions in a process termed photobiomodulation. LEDs stimulate respiratory metabolism in mitochondria and generate procollagen and other growth factors that promote cellular proliferation. Studies have confirmed shorter healing times and improvement in photoaging and acne following LED treatment. LED photomodulation is a quick, painless therapy that is safe for all skin types.
