hello I am 42 years old and doctors always told me I had a port wine stained. Wrong I just discovered I have a Nervus of Ota large one I shall say I am Mexican-American not Asian. It's very dark in my left eye one whole side of my left face and into my hair. I have been using CoverMark by Lydia O'Lairly make up it's great waterproof I can get most of it covered. You do know people are cure and they will always stare and say comments why do you wear so much makeup and I learned to ignore.
