Sclerotherapy effectively treats unsightly thread / spider veins primarily on legs . It's often considered the treatment of choice for small thread veins. Sclerotherapy involves injecting a solution directly into the vein.

The sclerotherapy solution causes the vein to scar, forcing blood to reroute through healthier veins.

The visible veins become less noticeable over the course of several months .

Usually several sessions are required depending on the case . Also compression tights are advisable for 10 days post each session.
