Do you put your eye liner on your water line?

Did you know that applying eye liner, foundation, powder, moisturizers etc. to the "water line" at the margin of your eye lids can cause dry eye and irritation? There are little glands in this area of your eye lid that secrete the oily layer of the tear film and by blocking them with makeup may cause red, dry, and irritated eyes. You can still wear eye liner just put it slightly below your lash line.
