In most cases, the problem is simply cosmetic and not a serious health hazard. You can blame it on your parents for the condition may be inherited. However, as trivial as their causes are, dark circles shouldn't be ignored for in some instances they may mean something else. If the problem persists or worsens, it's wise to see a doctor.

"Dark circles under the eyes can be the result of allergies to airborne substances, such as pollen, dust, and pet dander, because people rub their itchy eyes. People with hay fever may notice them at the height of the season," according to Cathy Wong of the American College of Nutrition.

"Blood vessels under the eyes can become dilated and engorged, which can contribute to dark circles. Excess dietary salt and smoking are common causes. Conditions that cause fluid retention (e.g. heart, thyroid, kidney, liver diseases) or medications that cause blood vessel dilation may be a factor. Your doctor should be aware of any symptoms you're experiencing," she added.
