Tattoo removal is most commonly performed using lasers that break down the ink particles in the tattoo. Tattoo removal has been performed with various tools since the start of tattooing. While tattoos were once considered permanent, it is now possible to remove them with treatments, fully or partially. Lasers remove tattoos by breaking up the pigment colors with a high-intensity light beam. Black tattoo pigment absorbs all laser wavelengths, making it the easiest color to treat. Other colors can only be treated by selected lasers based upon the pigment color. A tattoo removal process may take up to 6 months.
