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.
Conditions like fluid imbalance or local swelling that lead to puffy or swollen eyelids can cause shadows that make the area under the eyes appear darker. Trauma (a black eye) can cause darkening of the entire eye area. Some people notice that dark circles under the eyes tend to run in families, as well. In most cases, dark circles under the eyes are not a sign of a serious medical condition. Medically Reviewed by a Doctor on 3/6/2012.
