  Nd Yag Laser Tattoo Removal
It uses the theory that specific wave length (1064nm or 532nm) of laser will be absorbed by specific pigment. The high energy of laser, absorbed by the specific pigment, could cause the pigment to swell and explode, partial fragments of the pigment will be shot out of the body, and the other pigment fragments will be removed by your body's immune system over a period of time. Because the normal skin absorb little energy induced by laser at the wavelength of 1064nm or 532nm, so the laser could selectively targets and destroys tattoo pigments but not damage the surrounding normal tissues.
