This treatment is designed to diminish the appearance of spider veins in a simple, safe and effective procedure. The problematic vein is injected with a solution, which irritates the vein wall and causes it to close. You will begin to see results in 1-3 weeks. The procedure takes about 20 minutes and patients can immediately return to regular activities. Most patients who undergo 3-6 treatments will see the disappearance of treated veins within 1-3 months.
