Sclerotherapy for Veins

Sclerotherapy is the gold-standard treatment for spider veins and small varicose veins in the legs. A fine needle delivers a sclerosant solution directly into the vein, causing the vein wall to swell, stick together and gradually fade from view over several weeks.

The treatment has been used for over 80 years and has an extensive evidence base. Different sclerosant concentrations and formulations (liquid or foam) are used depending on vein size — foam sclerotherapy is particularly effective for larger reticular veins.

Key Benefits

• Evidence-based, highly effective for spider veins
• Both liquid and foam options for different vein sizes
• Minimal discomfort, no general anaesthesia
• Treated veins gradually fade over 4–8 weeks

Is This Treatment Right For You?

• Adults with spider veins or small varicose veins on the legs
• Patients who have ruled out significant venous insufficiency
• Those wanting a non-surgical cosmetic improvement to leg veins
