Naevi are birth defects consisting of clusters of pigment cells which have accumulated in the upper and in the middle layers of the skin.

The pigment chromophere can be virtually, totally eliminated with 1064 Q-Switched laser which seeks and destroys pigment cells. The damaged pigment cells are then absorbed by the tissue fluids and lymph and excreted through the system. Four to six sessions are required at 6 weeks interval to achieve best results.
