Anemia – iron deficiency may cause a blush tinge below the eyes. The skin usually look pale and the area around the eyes look darker. Include foods such as red meats, green vegetables, beans, raisins, eggs, and whole-grain breads that contain iron if you are deficient in iron.

Dehydration is among the main causes of dark circles under the eyes. If you don’t drink enough water everyday, you are not providing your body with as much water as it requires for flushing out toxins which often leads to dark circles under the eyes.

Nasal congestion can also cause dark circles under the eyes and swelling because the veins that drain from your eyes into your nose become dilated and darker.

Fluid retention is another cause of this condition. It often causes puffiness.

As we age the skin becomes thinner and thinner and more delicate. The skin becomes translucent, allowing the veins beneath prominent.

Extreme weight loss may also lead to dark circles. When you are losing weight too fast this can cause a sunken look.

Allergies can sometimes cause dark circles under the eyes –food allergy, an allergy to a chemical.

Poor diet – sometimes lack of nutrients can lead to our bodies breaking down which can lead to dark circles.
