Sclerotherapy Is a cosmetic procedure performed by injecting a solution directly into the vein which causes it to scar, forcing blood to reroute through healthier veins. The collapsed vein is reabsorbed into local tissue and eventually fades.
This process effectively treats varicose and spider veins. After the injection, treated veins tend to fade within a few weeks, although occasionally it may take a month or more to see the full results. In some instances, several sclerotherapy treatments may be needed.
