Hey, As you grow older, your skin loses its natural thickness and collagen. This can make the appearance of blood vessels underneath your skin more prominent. As a result, this area can look darker than usual. Other conditions, such as swelling near your eyes or fluid imbalance around the lower eyelids, can make your skin look darker. Dark circles under the eyes can have causes that aren't due to underlying disease. Examples include family history of dark circles, exhaustion, lack of sleep, allergies, eye rubbing or excessive sun exposure. We have listed some methods to reduce the appearance of dark circles under your eyes. Green Tea Bags Take two green tea bags and soak them in water. Refrigerate for a short while and place them on your eyes. Wash your face after 10-15 minutes. You can repeat daily until the dark circles fade away.
