Dark circles under the lower eyelids are common in men and women. Often accompanied by bags, dark circles can make you appear older than you are. To make matters worse, they can be difficult to get rid of. While fatigue may seem like the most logical explanation for this condition, there are a number of factors that can contribute to dark circles under the eyes. In most cases, they are no cause for concern and do not require medical attention.
Though they can affect anyone, dark circles are most common in people who:
- are elderly
- have a genetic predisposition to this condition (periorbital hyperpigmentationTrusted Source)
- are from non-white ethnic groups (darker skin tones are more prone to hyperpigmentation around the eye area)
WHAT CAUSES DARK CIRCLES?
There are a number of contributing factors for dark circles. Some common causes of include:
Oversleeping, extreme fatigue, or just staying up a few hours past your normal bedtime can cause dark circles to form under your eyes. Sleep deprivation can cause your skin to become dull and pale, allowing for dark tissues and blood vessels beneath your skin to show. Lack of sleep can also cause fluid to build underneath your eyes, causing them to appear puffy. As a result, the dark circles you see may actually be shadows cast by your puffy eyelids.
Natural aging is another common cause of those dark circles beneath your eyes. As you get older, your skin becomes thinner. You also lose the fat and collagen needed to maintain your skin’s elasticity. As this occurs, the dark blood vessels beneath your skin become more visible causing the area below your eyes to darken.
Staring at your television or computer screen can cause significant strain on your eyes. This strain can cause blood vessels around your eyes to enlarge. As a result, the skin surrounding your eyes can darken.
Allergic reactions and eye dryness can trigger dark circles. When you have an allergic reaction, your body release histamines as a response to harmful bacteria. Other than causing uncomfortable symptoms — including itchiness, redness, and puffy eyes — histamines also cause your blood vessels to dilate and become more visible beneath your skin. Allergies can also increase your urge to rub and scratch the itchy skin around your eyes. These actions can worsen your symptoms, causing inflammation, swelling, and broken blood vessels. This can result in dark shadows beneath your eyes.
