Laser vein removal can make spider veins fade, without any incisions or needles. The strong light beam from the laser causes them to dry up, but a few sessions are usually needed.
If the veins are more prominent, your doctor may recommend endovenous laser vein removal, in which they make a small incision and insert a laser-enhanced fiber into the vein. The heat energy will close the vein, and as in simple laser treatments, the vein will disappear over months. There’s no downtime, but you may have bruising or discomfort for a couple of weeks.
