However, there are also some chronic kidney problems can cause your dark circles under your eyes. In my opinion, you should go and see your GP and have some simple urine and blood tests done. So you can make sure if your symptom is caused by kidney problem or not. And also, stress, and bad life habits can lead to dark circles too. So you can have some Moisturizers containing Vitamin E and K, so that it can lessen the appearance of dark circles.
