Dark circles are characteristic bruise-like areas under the eyes, and a common beauty concern for many women. The skin around the eyes is very thin, (about 0.5 mm, 4 times thinner than in other parts of the face) the area is covered with many small blood vessels, which appear in a dark bluish shade for some people.
Possible causes for dark circles:
Genetics: Weak blood vessels that restrict hemoglobin (red blood cell) flow can be hereditary. When hemoglobin is low it causes a pigmented waste product that is deposited in the dermis and epidermis. The thinner the skin, the darker the circles will be evident.
Medical conditions: Cases such as allergies, asthma, eczema, liver problems and an iron deficiency can cause dark circles to develop under the eyes. additionally, some drugs expand blood vessels and cause the skin under the eyes to appear darker.
Aging and fatigue: As we age, our skin loses collagen, becoming thinner and making discoloration more apparent. Lack of sleep and constant fatigue are also causes.
Besides cosmetic components, there are other methods and tricks to prevent the formation of dark circles under the eyes:
Plenty of sleep
Drinking plenty of water, at least 2 L / day
Compresses soaked in chamomile tea or special cooling masks that are refrigerated prior to application can improve blood circulation and reduce dark circles
