The Star Walker uses 4 wavelengths (1064, 650, 585, 532 nm) to treat a wide variety of colors found in tattoos. Each color has it own wavelength of absorption of light and thus you need a specific wavelength to break the color apart with the least amount of injury to tissue. Other spots in the skin like age spots, malasma, hemangiomas or small veins can be treated in a similar manner. One treatment for the "age spots" on the chest, hands or face can be treated very well with green toning done by the 532 nm wavelength on our StarWalker.
