Abstract
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 m W. 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.
