What causes dark circles?
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.
How much do genetics influence dark circles?
Dark circles are certainly considered to have a genetic basis and can often be due to genetics. 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 circles. 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?
Excessive pigmentation can be caused by inflammation in the skin around the eye 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.
What environmental factors can cause dark circles?
Lifestyle and environmental factors can also aggravate dark circles or contribute to the development of them. These include: 
- a lack of sleep
- excessive alcohol consumption
- ultraviolet (UV) radiation exposure
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 which can mask, minimise and prevent hyperpigmentation.
What treatment options are there?
A spectrum of treatment options are available for hyperpigmentation. Among these are non-invasive options such as skin-protective or restorative creams and 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 which 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.
