  • TREATMENT OF A SKIN CONDITION USING A PIPERINE-BASED COMPOSITION IN CONJUNCTION WITH IRRADIATION
    Publication number: 20080146987
    Abstract: Embodiments of the present invention are directed to methods, apparatuses, and systems for the treatment of various skin conditions by delivery of piperine and/or a related structural analog of piperine (collectively referred to as piperine-based compounds) to an area of skin affected by a skin condition (e.g., vitiligo) in conjunction with irradiation of the affected area. Structural analogs of piperine include compounds such as THP, CHP, and RCHP. In various embodiments, irradiation of affected skin in conjunction with a piperine-based composition may result in stimulation of melanin synthesis by melanocytes which may induce pigmentation to a greater extent than with the use of the piperine-based compound alone.
