Spider veins, or telangiectasia, are small, dilated blood vessels that appear close to the skin’s surface, creating red, blue, or purple vein patterns. They commonly develop on the legs, face, and chest, often due to genetics, sun exposure, or prolonged standing. While spider veins are harmless, many individuals seek treatment to reduce their visibility and achieve clearer skin. Laser therapy can effectively target and collapse these veins, leading to a more even-toned complexion.
