Intense pulsed light (IPL) therapy uses a non-laser high-intensity source of light to treat facial spider veins, as well as a variety of other skin problems. When IPL is used to treat spider veins in the face, also known as telangiectasias, heat is generated within the vessel. This causes the walls of the vein to collapse on itself and stick together. Eventually, these veins will be reabsorbed by the body and fade away after several weeks. IPL in general affects the deeper structures with minimal damage to the surface of the skin. Multiple treatments may be necessary to treat resistant vessels and/or vessels that appear again.
