Sclerotherapy is one of the most common treatments for improving the appearance of spider and small varicose veins. It is an in-office medical procedure that takes about 30 minutes or longer, depending on the size and number of veins being treated. Treatment involves injecting a sclerosing agent into the vein. The vein fades over the next few weeks.
Typically, there is no downtime for returning to normal activities. After the procedure, you will wear compression stockings.
