Why Do I Get Dark Circles Under My Eyes

Are people constantly asking if you got enoughsleep last nighté Even if you snoozed for a solid 8 hoursé Well look alive! Today we're talking about the science behindthose dark circles under your eyes, and all the things that might cause them – tirednessincluded. There's a simple reason those eye bags lookall purpleish: just check out your wrists. If you can see the veins under your skin,they might look blue, even though the blood inside them is red.

That's because of the way that differentwavelengths of light interact with your skin and blood vessels, so more blue light is reflectedback into our eyes. The area under your eyes appears darker becausethe skin is thinner there, and doesn't have much fat. That means that more tiny blood vessels canshow through. People with darker skin have more of a pigmentcalled melanin in their skin. And sometimes they produce extra melanin belowtheir eyes – a condition called periorbital hyperpigmentation.

So based on the thickness of your skin andgenetics, you might be stuck with any dark circles you're born with. But there are things you can do to make themworse. People usually blame their dark circles ontiredness, and there probably is a correlation. See, when you're tired or stressed, yourbody produces more of a hormone called cortisol to get more glucose into your bloodstreamto give you the energy to stay awake. Over time, cortisol constricts some bloodvessels and dilates others, so it's possible that the vessels under your eyes are a littlebigger, which means darker eye circles.

Another culprit is allergies, or any sortof congestion. Allergic reactions can trigger your immunesystem to release these compounds called histamines, which causes blood vessels to dilate. Plus, itching and rubbing your eyes can makeany puffiness worse. So besides the dark circles from the builtupblood and inflammation, puffy eye bags can mean dark shadows. Not to mention, things like ultraviolet radiationin sunlight, which can damage to DNA in skin cells, which can kill them off.

And unfortunately, as we get older, we loseeven more fat underneath our skin and it gets thinner. Which means more, darker circles. So the best you can do: wear some sunscreen,take your allergy medicine, get a good night's rest, and try not to sweat the small stuff.
