Lowering skin melanin appearance with red light radiation and red light radiation kit therefor

A method of reducing appearance of melanin on the skin of a subject comprises exposing the skin to red narrow-band radiation at a wavelength(s) in a range of between 620 nm and 750 nm and having a band width of between 0 nm and 20 nm, in an effective dose to cause the appearance of the skin melanin to diminish and essentially not to cause photothermolysis of the skin. Alternatively, a method of reducing appearance of melanin on the skin of a subject comprises exposing the skin to non-coherent red narrow-band radiation at a wavelength(s) in a range of between 620 nm and 750 nm and having a band width of between 0.1 nm and 20 nm, in an effective dose to cause the appearance of the skin melanin. A portable kit for such a method comprises a radiation source generating red narrow-band radiation at a wavelength(s) in a range of between 620 nm and 750 nm, the narrow band radiation having a band width of between 0 nm and 20 nm and having a power density of between 10 mW/cm2 and 120 mW/cm2, and a manual instructing a user how to use the red narrow-band radiation for red narrow-band irradiation treatment to reduce appearance of melanin on the skin of a subject.
