It's possible. At present, plastic surgery hospitals generally use surgical methods to remove tattoos. The principle of laser tattoo removal is that laser instruments produce high-intensity beams, and different types of lasers can produce different colors of light. The naked eye color of laser is the key to treatment. Different colors of laser are absorbed by different colors of skin, and dye particles are decomposed and vaporized by laser energy, sealing blood vessels, and then the dye particles are absorbed by the body and excreted, and the pigment disappears. Because the laser of a certain wavelength is only absorbed by the pigment of the corresponding color. Only diseased cells can absorb specific laser, while normal skin tissue will not be damaged, so it will not leave scars.
