What Are Possible Complications? Rarely, bruising, overcorrection, persistent lumpiness or inflammation around the injection site may develop and persist for weeks after a procedure. If such a reaction should occur with hyaluronic acid, hyaluronidase may be injected to dissolve the filler and alleviate the problem. Allergic reactions to the older bovine collagen were common (about three percent). With the newer forms of fillers, allergic reactions are very rare (one in 5000 for hyaluronic acid). Rarely, injection of fillers may compromise blood flow to the skin, causing scab formation and possible development of a scar. This problem is very rare with the newer injectable fillers. Can Fillers Be Used Safely With Botox And Lasers? Yes, these modalities often compliment one another and recent studies support the safety and effectiveness of a combined approach to facial rejuvenation. What Are Spider (Telangiectatic) And Varicose Veins? Spider veins are formed by the dilation of a small group of blood vessels located close to the surface of the skin. Although they can appear anywhere on the body, spider veins are most commonly found on the face and legs. They usually pose no health hazard, but may produce a dull aching in the legs after prolonged standing and indicate more severe venous disease. Spider (Telangiectatic) And Varicose Veins Varicose veins are abnormally swollen or enlarged blood vessels caused by a weakening in the vein's wall. They can be harmful to a patient's health because they may be associated with the development of one or more of the following conditions: phlebitis or inflamed, tender vein; thrombosis or a clot in the vein; and venous stasis ulcers or open sores from inadequate tissue oxygen and fluid retention. Who Develops Spider And Varicose Veins? The exact cause of spider and varicose veins is unknown, although heredity, pregnancy and hormonal influences are believed to be primary factors contributing to both conditions. More than 40 percent of women have some form of varicose conditions, with an increasing incidence of venous disease as one gets older, so that up to 80% of women have some form of venous disease by age 80. Slightly more women than men have varicose and telangiectatic leg veins. What Is Sclerotherapy? Sclerotherapy is considered the gold standard treatment for removing spider and some varicose leg veins. It is a very cost-effective procedure that seldom leaves a scar or produces adverse effects. It is typically performed on an outpatient basis by a PREVIOUS NEXT
