      @Alex apparently when you are tired, your blood vessels expand, and the skin under the eye is very thin so you are basically looking at the darkness under the skin of your blood vessels.

      Part of the dark circles can also be dehydration! If the skin under your eyes thins out because it’s lost water, it’s easier to see the blood vessels there.
