Asclera yields excellent and immediate results on unsightly veins on the legs. It is injected directly into the veins causing micro scarring and permanent termination of blood flow through that vein. Generally one vial with 2ml of product will treat several small veins or 3-4 larger veins. This product can be used on varicose veins and has yielded excellent results. You should expect some redness and bruising at the injection sites. Both will resolve with healing.
