Cosmetic medical lasers designed to eradicate tattoos range from a single wavelength of light to a broad spectrum of light, the varieties of which are intended to obliterate the ink in the tattoo without damaging the skin. Certain colors of light are absorbed by specific corresponding colors of the tattoo ink. The light energy vaporizes or fragments the ink particles. Your body then absorbs these ink fragments naturally and the color fades over the next couple of weeks. This treatment is very similar to methods used for years to treat birthmarks.
