Expert answer:
Because you have a vein where you do not like I do not know, you have to ask your father and your mother were they who made you. It leaves its vein quiet if it is not bothering (health) does not have to do anything, now if it is bothering (aesthetic) there it can try: in very small vein cases a laser procedure can solve and if it is a larger vein there is no which do beyond surgical removal, but do not know if this type of surgery is done on the face. Find a vascular surgeon who can guide you better.
