Nd YAG laser tattoo removal machines use a 532nm/1320nm/1064/755nm laser technology to break down the ink particles in a tattoo. The laser of the tattoo removal machine and training emits a beam of light that is absorbed by the tattoo ink, causing the ink to heat up and shatter into smaller particles. These smaller particles can then be eliminated by the body's immune system. As a professional manufacturer and supplier of tattoo removal machines, we hope you can contact our factory in China.
