Spider veins are dilated blood vessels that lie near the surface of the skin. Varicose veins are veins that have become large and swollen. They can be painful. These occur due to weakening of the valves that typically function to prevent back flow of blood. When they weaken, the blood flows backward and the veins swell. Varicose veins have several causes. In fair-skinned people, sun exposure can lead to spider veins on the cheeks and nose.
Sclerotherapy is a popular treatment for bothersome veins. It is done by injecting a solution via a small needle into the vein to cause the walls to stick together and the blood to clot. Over time, the veins turn to scar and are absorbed by the body. Most patients can expect an 80-90% improvement with each treatment, however based on the amount of area being treated, multiple treatments may be necessary. Larger varicose veins may require surgery.
