Telangiectasia is a condition in which widened venules (tiny blood vessels) cause threadlike red lines on the skin. They’re sometimes known as “spider veins” when present in clusters.
Telangiectases are common in areas such as the face (nose, cheeks) & the legs. They develop gradually, but can be worsened by health and beauty products that cause skin irritation.They can cause discomfort to some people & they prefer to have them removed.
The exact cause of telangiectasia is unknown. It’s believed that most cases are caused by chronic exposure to the sun or extreme temperatures.
Ageing can weaken the blood vessels & exaggerate the condition. Regular topical use of corticosteroid thins and weakens the skin & can be the cause.
Some systemic diseases are correlated to Telangiectasias such as Rosacea, Systemic Lupus Erythematosus.
How is telangiectasia treated?
Treatment focuses on improving the appearance of the skin. Laser therapy is done by causing damage to the vessel and forcing it to collapse.
Sclerotherapy &/or Surgery are indicated if there is a problem in deep venous system (specially in the leg viens).
