Fibrovein is FDA approved for the treatment of small spider leg veins. The sclerosant is injected into the veins resulting in the vein collapsing and clearing over the forthcoming weeks. The sclerotherapy procedure takes about 30 to 45 minutes.
Most patients get an improved appearance of the legs. With over a 90 percent success rate, sclerotherapy can take 15 to 30 minutes to complete. Although the treated veins do not come back, new ones may appear after several years.
