Spider veins are small unsightly red or purple vessels on the surface of the face. They are often red or blue and are closer to the surface of the skin than varicose veins. They can look like tree branches or spider webs with their short jagged lines. Spider veins can also be found on the legs. They can cover either a very small or very large area of skin.
The causes of spider veins on the face include prolonged exposure to the sun, increasing age, trauma, medical conditions and certain habits such as smoking or alcohol. Women tend to be affected by spider veins 2-4 times more commonly than men do, due to the fact that female hormones and pregnancies are so commonly implicated in their cause.
