Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) lasers are frequently employed in tattoo removal procedures. These devices emit high-intensity light pulses at specific wavelengths (typically 1064 nm and 532 nm) that are absorbed by tattoo ink particles, fragmenting them into smaller pieces that the body’s immune system can then eliminate. Different wavelengths target different ink colors, with 1064 nm effective for darker inks like black and blue, and 532 nm suited for brighter colors like red and green.
This technology offers a significant advancement in tattoo removal compared to older, more invasive methods. Its precision allows for targeted treatment with minimal damage to surrounding skin, reducing the risk of scarring and promoting faster healing. The selective targeting of different ink colors also allows for more complete removal of multicolored tattoos. The development and refinement of these lasers have contributed significantly to the increasing popularity and accessibility of tattoo removal procedures.
