Lasers or light sources for treating port-wine stains

Port-wine stains are birthmarks caused by malformations of blood vessels in the skin. Port-wine stains manifest themselves in infancy as a flat, red mark and do not regress spontaneously but may, if untreated, become darker and thicker in adult life. The profusion of various lasers and light sources makes it difficult to decide which equipment is the best for treating port-wine stains.
