Sclerotherapy involves injecting a solution directly into the vein to improve the appearance of spider veins. The sclerotherapy solution causes the vein to scar, forcing blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades.  The treatment takes only 30-45 minutes based on the amount of veins requiring treatment.  Book a consultation with one of our nurses to learn more!  Photos from Asclera.com.
