Spider veins, also known as telangiectasias or venulectasias, are small, dilated blood vessels that appear close to the surface of the skin. They are typically red, blue, or purple and often resemble a spider’s web or a tree branch, hence the name “spider veins.” Spider veins can occur anywhere on the body but are most commonly found on the legs, face (especially around the nose and cheeks), and chest. Spider veins are similar to varicose veins but are smaller in size and located closer to the skin’s surface. They are usually not associated with any significant symptoms or health risks but can be a cosmetic concern for some individuals.
