Whether they're blue, brown, purple, or something else, dark eye circles can be a person's worst nightmare. Because of this, you probably do your best to get as much shut eye as possible (unless, of course, you're a mom.) But if you're getting your full eight hours each night and are still waking up to those pesky dark circles under your eyes in the morning, something else may be the problem. There are some surprising things that cause dark eye circles that have nothing to do with how many hours of sleep you're getting.
After taking a closer look at some of your habits, you may find that your makeup, your allergies, or even your parents are the real reason you are covering your eyes with concealer every morning in an effort to keep yourself from looking like a raccoon when you leave the house.
If you're brave enough to stop hiding behind those sunglasses for a few minutes, you should check out this list of surprising causes of dark eye circles and see if any of them apply. If so, you may want to find out what kind of concealer your grandmother has been using all of these years.
