Abstract

Light-emitting diode therapy was discovered in the late 1960s but only recently has it been widely applied in dermatology to treat a wide range of skin diseases including photoaging, scars, and acne. Since the introduction of photobiostimulation into medicine, the effectiveness and applicability of a variety of light sources have thoroughly been investigated. Light-emitting diode photomodulation is a nonthermal technology used to modulate cellular activity with light, and the photons are absorbed by mitochondrial chromophores in skin cells. Various beneficial effects of light-emitting diode at relatively low intensities have been reported, especially in indications where stimulation of healing, reduction of pain and inflammation, restoration of function, and skin rejuvenation are required. The light-emitting diode therapy is safe, nontoxic, and noninvasive with no side effects reported in the published literature.
