Covering dark circles can sometimes be difficult depending on your skin tone. The concealer you use for your dark circles should be different from the concealer you use to cover your blemishes. There are different types of concealers you can buy, but it will first take some self-examining. First try and detect the color of your dark circles, whether it is green, blue, or even a purple shade, that should always be your first step. Once you detect it, find a concealer that will neutralize it and brighten your eyes. Find a concealer that is one to two shades lighter than your natural skin tone as well to brighten your complexion.
