Low intensity light therapy for the manipulation of fibroblast, and fibroblast-derived mammalian cells and collagen

摘要

Disclosed is a method for treating various dermatalogical conditions using electromagnetic radiation. Particularly preferred are narrowband, multichromatic electromagnetic radiation emitters having a dominant emissive wavelength corresponding to the peak absorption wavelength of the mammalian tissue targetted for treatment. Topical compositions are disclosed for pretreating the targetted tissue to alter the peak absorption wavelength of the tissue.
