Dark eye circles are blood vessels under the eyes that can be seen through the skin. This area may appear in shades of blue, purple, brown, or black, depending on your natural skin color. Dark circles under your eyes may make you look tired or older than you are.
Dark circles under the eyes affect people of all ages, races, and genders. All skin types can also show dark circles to varying degrees. However, dark circles are more common in certain groups of people. These groups include the elderly, people with a family history of dark circles, and people with darker skin.
