Visual sclerotherapy at USA Vein Clinics is a minimally invasive, office-based procedure used to treat spider veins (telangiectasias) that lie close to the skin’s surface. A vein specialist injects a sclerosant solution directly into the vein, causing it to collapse and seal shut. Once treated, blood flow naturally redirects to healthier surrounding veins, and the faded veins are gradually reabsorbed by the body.
