Apparatus and method for high energy photodynamic therapy of acne vulgaris, seborrhea and other skin disorders

Abstract

An apparatus, a device, a system and a method for the phototherapy of different skin disorders including acne vulgaris, seborrhea and inflammation. The invention includes a multiple session treatment method by a high irradiance violet/blue CW time gated, or pulsed, light source with a spectral emission in the range of 400-450 nanometer and possible additional spectral bands in the green and red part of the spectrum. The apparatus includes at least one narrow spectral band light source with spectral emittance concentrated in the violet/blue spectral band. The invention can reduce the level of extra cellular pro inflammatory cytokines related to inflammation as well as to significantly reduce the acne bacteria population by a photodynamic effect. A system for the treatment of acne lesions combining the apparatus for the eradication of P. acne bacteria and the acne affected area inflammation and a device for the elimination of the red spots around the acne lesions using intense pulsed light in the spectral band 500-1000 nm.
