What is Sclerotherapy?

Sclerotherapy is an injectable procedure that treats superficial veins that show through the skin. A tiny needle delivers a specialized solution into the vessel, which irritates the lining and causes it to collapse. The body then reroutes blood to healthier veins and gradually clears the treated vessel.

How sclerotherapy works

After cleansing the skin, your dermatologist injects the solution directly into the vein. You may feel brief tingling or mild cramping. The treated vein collapses and seals. Over the following weeks, the body breaks down and absorbs it. Most sessions take under an hour and do not require anaesthesia.

What Does Sclerotherapy Treat?

Sclerotherapy is best for cosmetic spider veins and some small varicose veins, most commonly on the legs. It may also be used on small facial or body veins after evaluation.
