Sclerotherapy is a popular method of reducing the appearance superficial telangiectasias ("Spider Veins") in which a solution called a sclerosing agent, is injected into the veins.The injection causes a sclerosis or the formation of fibrous tissue in the vessel subsequent to an inflammatory reaction.This process causes a gradual fading of the treated vessel over a period of several weeks to several months.

The number of treatments differs from patient to patient, depending on the extent of spider-veins present.One to six or more treatments may be needed; the average is three to four. Individual veins usually require one to three treatments.

Sclerotherapy, or ‘injection therapy’, is the most common treatment for spider and varicose veins on the legs. During treatment, a mild chemical solution is injected into the incompetent vein or capillary.The sclerosing agent irritates the walls of the vessel, causing it to collapse.The body then absorbs the vein and blood is rerouted to a healthy vein, restoring proper venous circulation in the area.

A single sclerotherapy treatment session involves multiple injections. Patients describe the injections as feeling like a pinprick or mosquito bite.The number of treatment sessions needed will vary from patient to patient, depending on the number of veins treated, healing time and the level of cosmetic perfection desired. Following injections, a compression stocking needs to be worn to help keep the vein closed. Normal daily activities can commence immediately after treatment. Age revealing veins on the back of the hands can also be reduced with sclerotherapy.

Foam-Sclerotherapy is a new form of delivering the sclerosing agent. The foam solution has the consistency of shaving cream, which improves treatment in two distinct ways. First, the foam displaces blood within the vein, permitting the full strength of the sclerosing agent to be in direct contact with the vein wall for an extended period of time without any dilution effects. Second, the foam is visible via ultrasound imaging and can be easily tracked and guided to the source of the venous problem.
