Varicose Veins are enlarged, swollen veins raised above the surface of the skin, usually dark blue or purple in color, while spider veins are smaller, blue or red veins, that resemble tree branches or spider webs. Spider veins are generally found on the leg and face, while varicose veins are commonly found on the back of calves or inside of the leg. Sclerotherapy entails the injection of a FDA approved detergent directly into the vein to diminish their appearance. A combination of laser therapy in conjunction with Sclerotherapy may be necessary to achieve desired results for more resistant varicose veins.
