Those tiny blood vessels that typically crop up around your nose, cheeks or chin are common, dermatologists say. They're called telangiectasias or, informally, spider veins, because they look like spider webs, said Dr. Amy Huang, a dermatologist in New York City.
Sun damage is the No. 1 cause of spider veins on your face, Dr. Goldman said. Sun exposure destroys the coating that surrounds all blood vessels, known as the internal elastic lamina, which he compared to plastic wrap. When the coating is destroyed, it causes blood vessels to expand and become visible just under the skin.
