It emits a highly focused beam of laser light, which passes harmlessly through the outer layer of the skin and is absorbed primarily by the tattoo ink or the excess pigment with the lesion. As the light is absorbed, it is quickly converted to heat. The sudden rise in temperature with the treatment target fractures the ink or pigment into tiny particles. Tattoo ink fragments are carried away by the lymphatic system, while pigmented lesions are naturally shed from the skin one to two weeks after treatment
