Method 1 Addressing the Cause. Get your beauty sleep. Get plenty of sleep nightly. Itâs not entirely clear why inadequate sleep results in dark circles under the eyes, but lack of sleep tends to cause the skin to become paler (thus increasing the appearance of darkness under the eyes), and reduces circulation. Itâs also believed that too little time lying down is a cause in itself.
Other Causes of Dark Circles. Dark circles under the eyes may be hereditary. Because the skin under the eyes is very thin, when blood passes through the area it can produce a dark color, much like the blue color of your veins. The thinner your skin, the more the circles will be evident. Another cause can be overexposure to the sun. Another much-ignored cause of dark circles is allergies.
