Many causes are to blame in case of the dark circles. The primary one is fatigue. Another is eye strain.
Allergies can also cause under-eye circles and so can contact dermatitis, which happens when your eyes came in contact with something that causes mild irritation, like soap or makeup. Sun exposure can lead to irregular melatonin levels and cause your eyelid area to darken.
The skin under your eyes loses elastin and collagen and gets thinner with age. This makes the blood vessels underneath more visible, giving a darker look. In some cases it’s just genetics, otherwise known as bad luck.
