What Causes Dark Circles Under the Eyes?

Dark circles, also known as periorbital hyperpigmentation, are a commonly encountered condition best described as the darkening of skin pigmentation around the eyes. Whilst dark circles are not usually caused by an underlying medical condition, many people think they make them look tired, sad or older than they are, and therefore can affect their emotional well-being and quality of life1. Let’s take a look at what causes darkness around the eyes.

What causes dark circles under eyes?

The darkening of the pigment underneath the eyes can be caused by a number of environmental and biological factors. The reason for an individual’s dark circles may be that excessive pigmentation is simply genetic or hereditary. Other factors which may cause dark circles include allergies, skin laxity, and deep tear troughs, sometimes referred to as tear trough depression.

What environmental and lifestyle factors can cause dark circles?

Lifestyle and environmental factors are also reasons for dark circles under the eyes2:

  • A lack of sleep can cause skin to become dull and pale, which allows for dark tissues and blood vessels beneath the skin to show. As well as a result of extreme fatigue – or even just staying up a few hours past bedtime – dark circles can be caused by oversleeping3. Discover more on the importance of sleep for skin here.
  • Stress can not only have a negative impact on sleep, but can also break the fragile capillaries under the eyes which can give a dark appearance4.
  • Excessive alcohol consumption is dehydrating and can cause the skin beneath the eyes to thin and look sunken, due to their close proximity to the underlying bone5. 
  • Ultraviolet (UV) radiation exposure can cause the body to produce an excess of melanin, causing pigmentation around the eyes resulting in darkening of this area3. 
  • Smoking induces the secretion of Matrix Metalloproteinases, which, when produced in excess, causes the breakdown of vital collagen in the skin. When smoking obstructs the production of collagen or breaks it down, the skin on the face gets affected, with the under eye area being the most sensitive. It also affects the blood vessels under the eyes – and the collagen present in these vessels. They become bluish due to the lack of blood circulation6.

How much do genetics influence dark circles?

Dark circles are certainly considered to have a genetic basis. Some people are more likely than others to have excessive pigmentation, melanin deposition, or low levels of collagen in the area under the eyes - all of which contribute to the appearance of dark circles7,8. Although hereditary genetics can ensure one individual is more susceptible to dark circles than another, it is also recognised that stress, ageing and a lack of rest can cause pigmentary change.

What about the other causes of darkness around the eyes?

Excessive pigmentation can be caused by inflammation in the skin around the eyes as a result of allergic reactions and other dermatological conditions. Rubbing or scratching the skin around the eye, due to irritation, worsens inflammation, contributing to skin laxity and the appearance of dark circles.

Tear trough depression is another cause of dark circles and is primarily an age-related cause. As people age, the skin thins and becomes lax in the region. Coupled with a loss of the layer of fat under the skin, the shadowing of the tear trough is accentuated and causes dark circles to become visible under the eyes.

Can dark circles be prevented?

Avoidance of aggravating lifestyle factors can have a positive effect on the appearance of dark circles. Whilst hereditary causes of dark circles are almost impossible to avoid, there are a number of treatments that can mask, minimise and prevent hyperpigmentation.   

What treatment options are there for hyperpigmentation?

A spectrum of treatment options are available for hyperpigmentation. Among these are non-invasive options such as skin-protective or restorative creams, concealment and camouflage products, minimally invasive treatments such as soft tissue fillers and resurfacing, and more invasive treatments including surgical intervention.

Concealers and cosmetics are the least invasive option for the treatment of dark circles. Mineral make-up foundation can be used to blend skin tones and help conceal undesirable darker pigment in the under eye region. Similarly, there are topical treatments that can help combat the appearance of dark circles by tackling the underlying causes of skin laxity and thinness, UV light damage, and the build-up of fluid around the tear trough.
