These are small blood vessels under the surface of the skin. They may be red, purple, or blue. They are often seen on the face, upper chest, and neck. Related vessels called spider veins can be found in the legs. Removal is usually done for cosmetic reasons.
There are many causes of telangiectasias. These include heredity, sun damage, liver disease, pregnancy, emotions, hormones, some medicines, and rosacea. Treatment of these vessels may include lasers or sclerotherapy. Sclerotherapy is a procedure that uses a small needle to inject medicine into the vessels. This causes them to shrink. New vessels may continue to develop throughout the person's life. It depends on what causes them to form. KTP lasers and pulsed dye lasers are commonly used on the face.
