If you have chronic under eye circles, you may have "allergic shiners" which indicate a food or environmental allergy. Try to identify any possible allergens and avoid them for 10 days to see if you notice a difference. If you wake up with an occasional darkness under your eyes then try using arnica gel or skin care products containing arnica. Arnica has powerful anti-inflammatory properties that alleviate swelling and reduces the appearance of dark under eye circles.
