How do lasers remove tattoos?

Lasers produce short pulses of intense light that pass harmlessly through top layers of skin and are selectively absorbed by the tattoo pigment. The laser energy causes the tattoo pigment (or ink) to fragment into smaller particles that will be removed by the body's immune system. Doctors know which wavelengths of light to use and which method to use so the laser will deliver the best output to remove tattoo ink. In case you are wondering whether the laser might also remove normal skin pigment, you shouldn't worry. The laser selectively targets the tattoo's pigment without damaging the surrounding skin.
