Dark circles are due to lot of causes like hormonal changes, change in sleep cycle, etc. Always make sure you have a good sleep for making the day more fresh and energetic. You can chill and reduce the dark circles by keeping slices of cucumber or potato. A small tip could be freeze them for effective results.
