Poor Lifestyle Choices
While concealer can give your undereyes immediate brightness, your lifestyle habits really hold the power in the longterm appearance of your skin. For instance, drinking lots of water helps increase your blood flow. Batra advised to adhere to the "Eight by Eight" rule, wich involves ingesting eight 8-ounce glasses of water a day (a.k.a half a gallon). Exercise also helps improve circulation, which prevents blood from gathering as much under the eyes.
Batra added, “Foods rich in Vitamin K, which helps reduce blood clotting and strengthens capillary walls to prevent blood leakage, can also be somewhat helpful." Some examples are eggplant, kidney beans, grapes, and cucumbers.
Batra also warned against smoking: "It interferes with blood flow and can make dark circles worse."
