There are two causes of dark eye circles. Most people get dark circles because the skin around their eyes is really thin and the blood vessels underneath show through. Usually these types of circles are slightly purple or red. In these types of cases, a Vitamin K cream should help. The other cause is pigmentation around the eyes. Usually ethnic skin tones tend to have darker pigmentation around the eyes. For dark pigmentation, you can try a skin lightening cream with Kojic acid. Whatever you do though, make sure you find something that is gentle enough for the delicate skin around the eyes. Hope this helps!
