What are Spider Veins?
Spider veins are a group of widened capillaries & veins that can be seen under the surface of the skin. When these vein walls become weak or the valves controlling blood flow no longer function properly, it leads to an enlargement of the blood vessels.
These enlarged red, blue and purplish veins are commonly seen on the legs, especially on the upper thighs, sides of knees, and around the ankles. Spider veins can also develop on the face around the nose, cheeks, chin and even on your back.
