In some women, spider veins – those small clusters of red, blue, or purple veins that appear on the thighs, calves, and ankles – become noticeable at a young age. For others, the veins may not become obvious until much later. Leg veins, spider veins and other visible benign vascular lesions are common aesthetic conditions. Lasers and other light based technologies enable effective treatment of leg veins and vascular lesions by inducing vessel collapse through coagulation with minimal damage to adjacent structures.
