As Mari mentioned, you should rule out allergies. My daughter had dark circles for years and I always thought she was tired. I was sending her to bed early, even though she was telling me that she really wasn't tired. While at a routine physical appt, the doctor said it looked like she had "allergic shiners" and suggested allergy testing. She didn't have any symptoms other than the dark circles. We found out she is allergic to feathers, so having her go to bed early (to sleep on a feather pillow) was not the solution! Anyway, to get to the point, all the feathers are gone from our house and so are the dark circles. It's worth checking, mainly because if it is allergies, no beauty cream in the world is going to fix the problem.
