Causes of Dark Circles Under Eyes
Those dark circles under the eye are every girl's nightmare. This type of discoloration in the skin under the eyes tends to develop as a woman ages. So what causes these dark under eye circles?
Well, these dark circles are a by-product of oxidizing hemoglobin; the very same mechanism that produces bruises. This happens when red blood cells, which normally travel single file through your capillaries, get lost and wonder into the surrounding skin. Your body sends special enzymes to break down the red blood cells, including their hemoglobin (the molecule that gives them their distinctive red color).
It's the remaining components of this broken down hemoglobin that produces the dark blue color. Now this leakage takes place in other parts of your body as well. So why so noticeable under your eyes? It's because the skin in this area is some of the thinnest most translucent on your body. So in short, your dark under-eye circles are actually caused by leaky capillaries.
