Dark circles under the eye are otherwise called periorbital dark circles and they are a common sign of tiredness. Not only do they make an individual look older, they also indicate a lack of freshness.
But what are the possible causes of under eye dark circles? Can they mean anything more?
The main cause of under eye dark circles in scientific terms is because a thin layer of skin under the eye shows the blood vessels and the blood contained within it more clearly. Since sub cutaneous tissue only allows blue/violet wavelengths of light to pass through, these blood vessels give the impression of dark circles.
While make-up may be used to cover the dark circles, it may always not be possible to completely hide the same. The difference between a ‘black eye’ and ‘dark circled’ is also clearly discernable. While a black eye is because of injury, dark circles are more due to one of the factors enumerated below
Lack of sleep causes cortisol to be produced, to help the individual stay awake. When blood flow increases and the skin under the eye is thin (as in the case of most individuals), dark circles make an appearance. Fatigue and sleep deprivation are closely related and both are major causes of dark circles.
As we age, we lose the suppleness in our skin and it also starts getting thinner. This again can give rise to dark circles beneath the eyes.
Excessive drinking and smoking can also lead to the formation of dark circles. Caffeine is also a culprit in this regard.
Excessive exposure to the sun accelerates the production of melanin and this is also another cause of dark circles beneath the eye.
A sad but true fact is that dark circles may also be because of heredity problems. As an inherited trait, there is little control over the same.
The above are just some of the problems that cause dark circles beneath the eyes. Dark circles can also be an indication for a much bigger problem, including thyroid problems, periorbital cellulitis and trichinosis. Contact your wellness specialist today and lead a stress-free life!
