Aging blood vessels make You vulnerable to Dark Eye
Circles
The small blood vessels
present in your eye lids (capillaries) are delicate structures that are asked
to withstand years of fluctuations in blood pressure. External pollutants,
damaging U.V. rays, and poor diet result in the presen
ce of free radicals,
inflammatory molecules and hardening sugars that damage your capillary walls. These
damaged capillaries are susceptible to tears and can leak red blood cells into
the tissue. Once outside of the bloodstream, the red blood cells will rupture
and release iron-rich hemoglobin molecules that discolor the skin around your
eyes. If you've ever seen a rusty nail, you know that iron has a distinct
dark red color. When the hemoglobin collects in the tissue, it can cause an
underlying dark appearance similar to a bruise that is difficult to conceal.
Aging skin also makes You vulnerable to Dark Eye Circles
The skin is composed of
three major
layers, the epidermis, the dermis, and the hypodermis. The dermis has the
largest volume because it contains a collagen and elastin mesh fully hydrated
due to the presence of a water-hoarding molecule called hyaluronic acid (HA).
HA can hold up to 5000 times its weight in water! Young skin is smooth and
elastic because it contains high concentration of HA and a healthy intact
collagen and elastin network.
Stress, free-radicals, and age result
in damage to the collagen and elastin network, and the skin cells (fibroblasts)
slow down their production of these essential proteins. In addition, the skin
gradually decreases the production of HA, and this dehydration results in the
collapse of the collagen network resulting in a thinner dermis. The skin
surrounding your eye is some of the thinnest skin on your body, making it one
of t
he first places that age damage becomes visible.
The overall result is that as
you age, your collagen and elastin network begins to collapse and your dermis
becomes thinner and thinner, your blood vessels become increasingly easy to see
through the epidermal layer, thus creating a
discolored skin tone around your lower eye lid.
