Raw potatoes contain natural bleaching agents that will assist in lightening up dark circles and ride the puffiness around your eyes. Grate two raw potatoes to extract the juice from them. Soak a cotton ball in the juice and place it over your closed eyes. Make sure that the juice fully covers the dark circles under your eyes. All the juice to sit on your eye for fifteen minutes and rinse with cool water. Repeat process once daily and in two weeks you will have noticeably less dark circles.
