Telangiectasia is a condition in which widened venules (tiny blood vessels) cause threadlike red lines or patterns on the skin. These patterns, or telangiectases, form gradually and often in clusters. They’re sometimes known as “spider veins” because of their fine and web-like appearance.
Telangiectases are common in areas that are easily seen (lips, nose, eyes and cheeks). They can cause discomfort, and some people find them unattractive. Many people choose to have them removed. Removal is done by causing damage to the vessel and forcing it to collapse or scar. This reduces the appearance of the red marks or patterns on the skin.
