Working Principle:
Laser emitted by the system has a strong penetration ability which allows it to
reach the deep layer of dermis. The pigment particles absorb the light energy
and explode sharply, burst into the tiny pieces, thus diminish the color density
and get rid of it.
So the appliance can effectively do away with mutant pigmentations and
vascular tissue based on undamaged ambient tissue. This is called „Selective
