Varicose veins treatment. Gloved hand injecting a sclerosant into a patient's leg to treat varicose veins. The paths of the veins are marked in purple on the skin. A sclerosant is a substance which causes irritation of the veins' linings,leading to scarring and their subsequent destruction. The body naturally re-routes the blood supply around the affected area.
