SCLEROTHERAPY
Sclerotherapy has been used in the treatment of spider veins, also known as telangiectasias or sunburst varicosities. These are small, thin veins located near the surface of the skin. Although these super-fine veins are connected with the larger venous system, they are not an essential part of it. Occasionally, spider veins appear on the face. Injecting the unwanted veins with a sclerosing solution causes the target vein to immediately shrink, and then dissolve over a period of weeks as the body naturally absorbs the treated vein.
