Working Principle:The energy of Q-switched ND:YAG laser can be absorbed by the blue and black melanin.The melanin will be fragmented so small that they can be metabolized by the lymphatic system or egested out of the body. Thus the tattoo or other pigmentations will be removed without damage to norm

Principle of Picosecond Nd:YAG laser:The freckle removal machine operates by outputting a high energy Q-switched ND:Yag laser, which breaks pigment molecules into smaller and smaller particles. Some of the pigment particles will dissipate while others will be removed by the body's immune system or l
