Lack of sleep is a major cause of pesky, dark under eye bags; however, it is by no means the only factor. Sleep contributes to our overall health, so make sure to catch the right amount of Z's to feel energized, but not too much that you feel lethargic. Swelling around the eyes can be cause by sleep deprivation as well as getting too much sleep.
Unfortunately, if dark under eye circles run in your family, you're quite likely to get them as well. If this is true for your tired-looking eyes, you may find them difficult to treat, so try not to be too hard on yourself.
A diet that is high in salt will cause you to retain more water and can cause puffiness around the eyes. And if your diet is lacking in essential nutrients or vitamins, your skin may become thinner and translucent, making dark under eye circles more noticeable.
