Using a cool compress under the eyes can also help in reducing inflammation (that increases blood flow and amplifies dark circles). If you've had this problem for some time (i.e years), then its likely hereditary, so you may want to use some cosmetics (like a concealer or a powder) to hide the problem. If the dark circles have just appeared recently, they can be caused by a lack of sleep, allergies, an illness or even sinus congestion; so its worth visiting a doctor if you suspect something else is going on. (Sometimes our bodies tell us that something is wrong in strange ways).
