What Causes Dark Circles Under Eyes? What to Watch Out For!

There are common and various reasons why dark circles develop, and finding out why can help you know what solution to follow. So, what causes dark circles under eyes?

What Causes Dark Circles Under Eyes?

1. Did You Get Enough Sleep?

This is the most common reason why people have dark circles under their eyes. A lack of sleep and too much sleep can cause dark circles. Oversleeping or extreme fatigue, as well as even just staying a couple of hours past your typical bedtime, may end up with you waking up with dark circles.

This is because sleep deprivation causes the skin to become dull and/or pale, which allows dark tissues and blood vessels underneath the skin to show. Furthermore, lack of sleep may cause fluid build-up under the eyes, which is why they sometimes look puffy. The dark circles may be shadows from puffy eyelids.

2. Natural Part of Aging

Another common cause of those dark circles under your eyes is aging. When you turn older, the skin becomes thinner and you begin losing fat and collagen, which are required to maintain skin elasticity. 

As a result, the dark blood vessels under your skin will become more visible, which causes the areas under the eyes to darken.

3. Eye Strain

If you are in front of a computer or television screen for hours on end, without any breaks, that can be straining on your eyes. This strain would result in enlarged blood vessels around the eyes. This may cause the surrounding skin of the eyes to darken.

4. An Allergic Reaction

Both allergic reactions and dry eyes may trigger dark circles.

If you experience an allergic reaction, the body will release histamines, responding to the harmful bacteria. As this occurs, you’ll experience a few symptoms, such as itchiness redness, and/or puffy eyes. Histamines may also cause the blood vessels to dilate, making them look more visible from under the skin.

Also, because allergies may increase the urge to scratch and rub your eyes, it can worsen the symptoms and cause inflammation, swelling, and even broken blood vessels. This is what causes dark shadows under the eyes. 

5. You’re Dehydrated

This is another common reason why people have dark circles under their eyes. When the body doesn’t receive the right amount of water, the skin under your eyes will begin to dull, with your eyes looking sunken.

6. Too Much Sun

Sun overexposure may cause the body to produce too much melanin, which is a pigment providing the body with color. Too much sun around the eyes might cause the pigmentation in the surrounding skin to darken further.

7. It’s Part of the Genes

Your family history can play a part in the dark circles developing under the eyes. It might be an inherited trait that shows in childhood, which might worsen or disappear with age. Inheritable medical conditions may also result in dark circles under the eyes.
