Working overtime, partying out or simply sleeping late at night are just some of what we believed could cause dark circles under the eyes. That’s why sleeping late often worries us but do you know that these believed causes are not really directly related to dark circles. I read in an article, which research dermatologists agreed to, partying out at night, working overtime and sleeping late have nothing to do with those dark circles that are visible under your eyes. It is explained that “a complex interaction between your body and the same kind of chemical reaction that produces bruises is what really causes dark circles" and that tanning could make it worse. The simplest way to hide those dark circles is applying eye creams. Might as well choose the best eye cream for dark circles for best result. There are list of best eye creams you can refer to. Also, read reviews before deciding to buy.
