Dark circles under the eyes occur when the blood vessels surrounding the eyes become engorged. Puffy eyelids can also cause dark under-eye circles by casting shadows on the area. According to the Mayo Clinic, causes of dark circles around the eyes include allergies, heredity, nasal congestion, thin skin and certain lifestyle factors, such as smoking. If you are unable to get rid of dark circles naturally, speak to your doctor about other possible treatment options.
Moisten a washcloth with cold water. Put the washcloth on the eye area. Leave in place for a minimum of 10 minutes. To keep the washcloth cold, wring it out and re-moisten it with cold water every couple of minutes. The cold constricts blood vessels to get rid of them.
Eliminate certain substances from your diet. The Mayo Clinic says that drinking too much alcohol or caffeinated beverages can be causes of dark circles. Get rid of the circles naturally by avoiding these drinks.
Steer clear of common allergens. Since allergies can cause dark circles under the eyes, eliminate exposure to allergens, such as dust, pollen and pet dander, according to “The Doctors Book of Home Remedies II” found on the Mother Nature website. If you have a food allergy, such as wheat or milk, avoid exposure to these substances as well.
Protect the eyes from the sun. Since sun exposure can cause dark circles, wear sunglasses or stay out of the sun.
