Studies suggest that approximately 50% to 80% of treated veins may be reduced after sclerotherapy¹. If the veins respond to treatment, they are less likely to reappear, as the sclerosing agent supports vein closure².
Spider veins may show improvement within 3 weeks, while larger veins can take 3 to 4 months. However, results vary among individuals depending on vein size, location, and the body’s ability to process treated veins³.
