During a laser vein removal treatment a concentrated beam of light energy from the laser is directed precisely at the small blood vessels.  The light penetrates below the surface of the skin and the heat causes the blood within the tiny vessels to coagulate.  The walls of the vein collapse, blood flow is stopped and over the next two to eight weeks the vein is absorbed into the body and disappears. Blood flow will then be redirected to veins deeper below your skin’s surface where it should be.
