Sclerotherapy is the injection of small amounts of an irritating solution into unwanted spider veins of the thighs, calves, and ankles. This relatively painless procedure causes the vessels to collapse and fade from view.
One to four treatments may be needed to acquire desired results depending on the number of vessels being treated. Sclerotherapy is often combined with laser treatments for optimal results. Support hose are often recommended to be worn for a short period after treatment.
