How Can You Get Rid of Veins Under Your Eyes?

I have greenish veins under my eyes and it makes me look terrible. I've tried make-up to cover it but NO makeup that I ever tried worked. I want to get rid of them permanently so is there any medicine specifically for the veins? If not, is there any natural way to get rid of them? I might be looking forward to laser removal for the veins but I'm scared that it might not work. One more question-- how old do you have to be in order to get laser vein removal. Please help! Thanks :)
