Abstract: Photosensitizer mixtures and method of treating cellulites by light illumination are presented. Photosensitizer is combined with cellular products, e.g. adipose cells, collagen, previously removed by liposuction. Concentrations used depend on treatment area, cellulite stage and whether cellulites are in depressed or elevated skin areas. The cosmetic treatment reduces/removes localized lipodystrophies, flaccidity, cellulite using localized laser, LED, etc emissions. Applied light energy destroys “fat” cells by a combination of chemical reactions primarily, and temperature, wherein cell walls break releasing cell fluid. Transmission devices guide radiation to the treatment site. One or more light sources like laser diodes or LEDs may be coupled into one or more optical fibers to increase the covered area and increase the amount of radiation in that area. Optical fibers can be introduced percutaneously or interstitially. Cell fluid in the treatment area is removed by a combination of techniques.
