Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the reduction of acne and acne related bacteria using low-intensity light therapy. In an illustrative embodiment, skin containing acne bacteria is treated with a series of pulses of light from a light emitting diode. The LED has a dominant emissive wavelength of about 660 nm and an energy output of about 4 mW. The acne bacteria-containing tissue is exposed to pulses from the light source about 100 times for about 250 milliseconds per pulse, with an interpulse interval of about 100 milliseconds.

La présente invention concerne un système et un procédé pour traiter les troubles cutanés. Plus particulièrement, l'invention concerne la réduction de l'acné et des bactéries causant l'acné à l'aide de la photothérapie basse intensité. Dans un mode de réalisation illustratif, une peau contenant des bactéries causant l'acné est traitée avec une série d'impulsions de lumière provenant d'une diode électroluminescente. La LED présente une longueur d'onde émissive dominante d'environ 660 nm et un rendement énergétique d'environ 4 mW. Le tissu contenant les bactéries causant l'acné est exposé à des impulsions en provenance de la source lumineuse environ 100 fois pendant environ 250 millisecondes par impulsion, l'intervalle entre les impulsions étant d'environ 100 millisecondes.
