Telangiectasia / Broken capillaries

What are broken capillaries?

Broken capillaries, or 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 weblike appearance.

What causes broken capillaries?

The exact cause of telangiectasia is unknown. Researchers believe several causes may contribute to the development of telangiectases. These causes may be genetic, environmental, or a combination of both. It’s believed that most cases of telangiectasia are caused by chronic exposure to the sun or extreme temperatures. This is because they usually appear on the body where skin is often exposed to sunlight and air.

Other causes are:

• Pregnancy
• Aging
• Rosacea
• Alcohol consumption
• Corticosteroid use
• Scleroderma
• Dermatomyositis
