Nasal telangiectasia is a benign skin condition that can occur in otherwise healthy people. In some cases, it may be a symptom of serious illness.
The causes of telangiectasia are unknown, but researchers think they may be genetic, environmental, or a combination of both. It’s believed the most common causes of telangiectasia are chronic exposure to the sun and extreme heat or cold.
In telangiectasia cases that are not life-threatening, treatment is optional and may be done to improve skin appearance. To prevent telangiectasia, protect your skin from the sun and extreme temperatures.
What is Nasal Telangiectasia?
Nasal 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.
Telangiectases are common in areas that are easily seen (such as the lips, nose, eyes, fingers, 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.
Recognizing the Symptoms of Telangiectasia
Nasal telangiectases can be uncomfortable. They are generally not life-threatening, but some people may not like how they look. They develop gradually, but can be worsened by health and beauty products that cause skin irritation, such as abrasive soaps and sponges.

- threadlike red marks or patterns on the skin
What Are the Causes of Nasal Telangiectasia?
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 is 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 possible causes include:
- alcoholism: this can affect the flow of blood in vessels and can cause liver disease
- pregnancy: pregnancy often applies large amounts of pressure on venules
- aging: aging blood vessels can begin to weaken
- rosacea: enlarges venules in the face, creating a flushed appearance in cheeks and nose
- habitual corticosteroid use: thins and weakens the skin
- scleroderma: hardens and contracts the skin
- dermatomyositis: inflames skin and underlying muscle tissue
- systemic lupus erythematosus: can increase skin sensitivity to sunlight and extreme temperatures
