Method of treating acne
First Claim
1. A method of treating acne with red light radiation, the method comprising the steps of:
- (a) providing a plurality of light emitting diodes which generate non-coherent radiation in a narrow bandwidth centered at a wavelength of approximately 660 nm,(b) driving the diodes exclusively in a continuous wave mode to generate the non-coherent radiation,(c) concentrating and projecting the non-coherent radiation on a dermal area afflicted with acne without simultaneously illuminating the area with non-coherent light emitting diode radiation centered about a different wavelength and(d) maintaining the concentrating and projecting step (c) for a prescribed treatment duration.

Abstract
A method of treating acne by illumination comprising the steps of utilizing at least one light emitting diode (LED) by driving each of the at least one LEDs in substantially continuous wave (CW) mode of operation to generate CW light radiation in a narrow bandwidth centered at a wavelength suitable for acne relief, concentrating and projecting the CW light radiation onto an acne-affected dermal zone for biostimulative treatment thereof and maintaining the light radiation for a prescribed treatment duration, wherein each of the at least one LEDs emits light of substantially the same wavelength and wherein the acne affected dermal zone is not simultaneously illuminated by stimulating radiation of another wavelength.
