There are a few methods for reducing the appearance of dark circles without makeup. Try a retinol cream, or vitamin C lotion dabbed gently under the eye as these can even out tone and reduce the appearance of fine lines and wrinkles. Alternatively, try caffeine in the form of cooled teabags pressed under your eyes or a serum. Caffeine can stimulate blood flow and shrink the blood vessels reducing puffiness. You can also use a jade roller to massage a cooling aloe vera gel under your eye. Lastly, try under eye masks that are full of nourishing ingredients.
