The aforementioned pointers are surely some of the reasons behind getting into dark circles but some more are mentioned below that also seem relatable in terms of our daily lifestyle.
Because the lower eyelid skin is one of the thinnest areas of skin on the body, it allows subdermal characteristics to be highlighted, and dark under-eye circles become highly obvious. Because there is little to no subcutaneous tissue, the skin does not have the same support and fullness as the rest of the face. This causes more pronounced age changes compared to the rest of the face skin. Another concern is that as a result of collagen and/or elastin loss, aging and environmental changes across the face result in a loss of suppleness and tone. You'll want to use an eye glow gel designed specifically for it.
