Genetics - these are the most common cause of under-eye circles. If you inherit thin or fair skin, the blood vessel supply to your eye area is more obvious.
Allergies - another key cause of dark circles under eyes, as they trigger the release of histamines in the body which swell the blood vessels.
Ageing - As we get older, our skin loses collagen and elasticity, and appears thinner, showing the blood vessels more prominently.
Not sure if it's your age or allergies at the root of the cause? Gently stretch the skin under your eyes - if the area becomes darker, the circles are probably due to ageing or genetics, but if it doesn't change, it may be your allergies. For allergy related dark circles, take an over-the counter antihistamine.
Assuming your dark circles are not an underlying health problem, there are many different ways to manage their appearance just through simple remedies and adapting your lifestyle.
