PDT TREATMENT METHOD FOR CELLULITES AND COSMETIC USE

摘要

A photosensitizer mixture and a method of treating cellulites by means of a percutaneous application of the mixture into the area of cellulite buildup followed by light illumination are presented. The photosensitizer can be combined with one or more cellular products including adipose cells and/or collagen that have been previously removed by liposuction. This mixture can also include other compounds such as Lipofundin MCT 10 % to improve the photosensitizer's diffusion or to dilute it Varying concentrations are used depending on the area of treatment as well as the stage of the cellulites an d whether the cellulites present a depressed area in the skin or an elevated area. The cosmetic treatment method substantially reduces or removes localiz ed lipodystrophies and/or flaccidity and/or cellulite by localized laser, LED o r other light irradiation of the area of treatment having a photosensitizer applied therein. The light energy is applied to destroy the "fat" cells by a combination of chemical reactions, primarily, and temperature wherein the ce ll walls break releasing the cell fluid. The light radiation is generally appli ed through devices to guide the radiation to the area of treatment. One or more light sources such as laser diodes or LEDs may be coupled into one or more optical fibers to increase the area of coverage as well as increase the amou nt of radiation in that area of coverage. Optical fibers can be introduced percutaneously or possibly interstitially into the area of treatment. Cell fluid in the area of treatment is removed by a combination of techniques. Quick and lasting cosmetic changes in areas having prior untreatable celluli te fat tissues are achieved while minimizing trauma.
