Pigment particles are crushed into tiny fragments by laser, which are discharged through skin scabbing, or discharged through blood circulation and phagocytosis of cells to complete pigment metabolism.

2. Skinning method

Use a special high-speed rotating grinding wheel to polish the skin surface to remove pigment.

3. Freeze and decolorize.

Liquid nitrogen evaporates from liquid to gas at-169℃, taking away part of the moisture in the skin, causing the skin to die and regain its weight.
