Sclerotherapy is a medical procedure whereby a chemical, the sclerosant, is injected into a vein to entirely obliterate it. The sclerosant damages the innermost lining of the vessel (the endothelium), resulting in a clot that blocks the blood circulation in the vein beyond.

Laser vein removal is a technologically advanced procedure designed to diminish both spider and varicose veins using a highly concentrated beam of light energy. Laser spider vein removal and laser varicose vein removal are popular because they are minimally invasive, virtually pain free, and require no general anesthesia.
