Sclerotherapy

Sclerotherapy was developed in  the 1920s for the treatment of spider veins (small purple blood vessels).  Spider veins are hereditary, and while most commonly found on the thigh or  lower leg, they can form virtually anywhere on the body. Occasionally, spider  veins will appear on the face. A sclerosing solution is injected into the vein  with a micro-needle. The solution causes the vein to turn white (blanch), and  then gradually disappear.

A typical treatment lasts  from 30 minutes to an hour. Complete correction is not expected on the first  treatment. Only about 50 to 70% of the treated vessels will be permanently  gone. Three to 4 treatments are generally required for optimal results.
