Dark circles can be caused due to sun damages, unhealthy food, lack of water, stress, lack of sleep. To get rid of it you have to avoid junk food, take less stress, take sleep at least 6 hours. Apply cucumber slices over your eyes for 15 minutes.
Hi,
Dark circles under the eyes are most often caused by allergies, illness, a lack of sleep, or heredity. If your dark circles are caused by heredity, you may find that they are almost impossible to completely eliminate.
In the morning, wash your face with cold water to help blood vessels constrict. Then, apply an eye cream that contains Retinol and vitamin K. Eat plenty of fruits and vegetables to prevent the vitamin deficiencies that can affect your skin’s appearance. Reducing your salt intake will also help improve the look of your skin. One treatment is to massage almond oil with honey around the eyes before going to bed.

If you’re feeling very self-conscious about dark circles under your eyes, you can try to use makeup to help camouflage the problem.
