Sclerotherapy
Sclerotherapy is a very safe and well-established treatment for removing unsightly thread and spider veins. It is a simple non-surgical procedure that usually takes 30 to 40 minutes and is performed under local anaesthesia.
This solution causes swelling, which closes off the veins and prevents blood from flowing through them. As a result, blood is rerouted through healthier veins, and the discolored, swollen veins are eventually absorbed by your body.
