The Q-Switched Nd: YAG laser works by targeting specific pigments in the skin, which TARGETS the damaged skin cells in the treatment area. When it comes to laser tattoo removal, the Q-Switched Nd: YAG laser targets ink pigment and breaks it up into smaller particles through powerful bursts of energy. The ink is then absorbed into the bloodstream and eventually expelled from the body. The Q-Switched Nd: YAG laser utilizes two energy frequencies; 1064 nanometers, to target deeper skin layers, and 532 nanometers, to address hyperpigmentation and more superficial layers.
