When you don't get enough restorative sleep at night, your blood vessels dilate. This causes an increase in blood flow, and since the skin under your eyes is thinner, the dark tint caused by the increased volume of blood is more noticeable here. In other words, sleep deprivation causes dark circles.

Black Eyes Have you ever seen someone with eyes that seem black as night? Although they appear black, they are really just a very, very dark brown, which is caused by an abundance of melanin. You may only be able to determine the pupil from the iris when looking at the eye with a bright light!

The skin around your mouth can become dark due to hyperpigmentation [1], which is a very common cause. Hyperpigmentation is the excess production of melanin in certain areas of the skin, which make those patches darker than the rest of your skin. Hyperpigmentation can affect people of all ages and different skin types.

Puffy, swollen eyelids and dark circles under the eyes can occur when you have an eye infection such as pink eye. These swollen eyes are caused by inflammation associated with the eye infection, which directly affects the neighboring eyelids. Also, dry eyes can cause general puffiness and swelling.

It's not an urban legend — falling short on your zzz's, whether due to insomnia or simply a late night, can cause circles under your eyes to appear or become more prominent. This happens because lack of sleep tends to cause the blood vessels under the thin skin of the eyes to dilate, creating a dark tint.

Genetics. Family history also plays a part in developing dark circles under your eyes. It can be an inherited trait seen early in childhood, and may worsen as you age or slowly disappear. Predispositions to other medical conditions — such as thyroid disease — can also result in dark circles beneath your eyes.

Sometimes black eyes can occur without trauma affecting the eye. If you have bad nasal allergies, you can get “allergic shiners.” These shiners may cause dark circles or the appearance of a black eye because blood flow is slightly hindered.

Another cause of dark circles is the natural aging process. When you age, you tend to lose fat and collagen, and your skin often thins. This can make the reddish-blue blood vessels under your eyes more prominent. Also, as people age, they commonly develop puffy eyelids or hollows under their eyes.

Dark circles in children are typically caused by allergies and nasal congestion, which can thin the skin around the eyes, revealing the blood vessels. Congestion is swelling in the tissues that line the inside of the nose. Congestion dilates blood vessels, which increases blood flow in the area.

Drinking enough water can do wonders for under-eye skin. Cut back on alcohol, caffeine and salt. Alcohol and caffeine cause dehydration, making dark circles more obvious. Salt can cause you to retain excess body fluid, causing puffy skin and under-eye bags.

4. Dark Lines: Melanoma. Even if you're diligent about checking your skin for dark spots and other signs of melanoma — a type of skin cancer — you might forget to check your nails. Melanoma can appear as a dark streak under your nail, distorting its color.

Whether this is caused by allergies, insomnia, or a medical condition, wearing a cool eye mask could help solve the problem. The coldness restricts the blood vessels surrounding your eyes, and that will alleviate the dark coloring for a short period of time.
