How effective is vitamin K in treating spider veins?

Unfortunately, some manufacturers of spider-vein therapies claim vitamin K is the secret weapon, as it can constrict blood vessels to make them less visible, but its molecules are simply too big to get through your skin’s layers. Even if it did reach the veins it wouldn’t do anything: Vitamin K is involved in the clotting cascade when you are actively bleeding. The best way to tackle spider veins is with sclerotherapy. A doctor will inject tiny amounts of a solution (hypertonic saline or sotradechol are among the most popular) that causes the veins to swell shut. About 95 percent of patients see an improvement after one to three sclerotherapy treatments.
