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

摘要

An apparatus and method for the phototherapy of different skin conditions, particularly acne vulgaris seborrhea and inflammation. The invention consists of a multiple session treatment method by a violet/blue 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 and possibly with the topical application of oxygen transporting compounds, and/or a methylene blue solution. The apparatus includes at least one narrow spectral band light source with spectral emittance concentrated in the violet/blue spectral band. The apparatus use the radiation to reduce the level of extra cellular pro inflammatory cytokines related to inflammation and to significantly reduce the acne bacteria population by a photodynamic effect.
