The light penetrates skin and it is absorbed by pigment in ultra-short nanosecond (6ns) and results in an instantaneous blast. The pigment particles are shattered into fragments; parts of them will be bounced out of the skin and the other parts will be spilt into tiny particles that can be engulfed by phagocytes and then eliminated by lymphatic system.
