Dark circles usually occur in people with irregular life schedule. Because of the slow blood flow in the capillaries, the increase in blood volume and the increase in oxygen consumption, the result of an increase in hypoxic hemoglobin, the skin appears dark blue from the outside.
Due to the many capillaries around the eyes, lack of sleep, eye fatigue, stress, anemia and other factors can cause congestion and swelling of the skin around the eyes, as well as the formation of dark circles.
Dark circles are mainly caused by the accumulation of eye pigments, and the metabolic wastes around the eye skin are not eliminated from the body in time.
What are the reasons cause of dark circles?
- Irregular life schedule
Often staying up late, emotional instability, eye fatigue, aging, venous blood flow slow, insufficient oxygen supply of red blood cells around eye skin, excessive accumulation of carbon dioxide and metabolic waste in the venous blood vessels, forming chronic hypoxia, dark blood form stagnation and cause eye pigmentation.
- Pigmentation
Since dermis melanin accumulates more on the surface of the skin, the skin around the eyes is thinner, so the skin looks darker. Some people are born with melanin deposition, but acquired sun exposure and drug intake can also cause melanin deposition.
- Poor blood circulation around the eyes
Due to lack of sleep, eye fatigue, anemia, allergic rhinitis and other reasons, blood flow around the eyes is slow, blood vessels dilate, and the skin around the eyes is congested and swollen, making the eye skin look dark.
- Chronic
Anemia, chronic nephritis, chronic hepatitis, or some internal organ diseases may cause dark circles.
Because these chronic diseases cause excessive consumption of nutrients in the patient, the fat layer is contracted, which leads to the production of pigments around the eyes.
- Vascular problems
Blood vessels are also a common factor that can cause dark circles. Some people have more or expanded blood vessels in the skin around the eyes due to natural or other stress factors. These changes are enough to make the skin darker and appear dark circles.
- Cosmetic residue
Long-term cosmetic residues and unclean makeup removal will cause pigmentation to the fragile eyelids, eventually leading to dark circles.
Therefore, it is necessary to carefully remove makeup, especially when removing eye makeup.
- Senescence
As the age increases, collagen will gradually be lost, and the eye skin lacks elasticity and luster, which leads to thinning of the skin and the formation of wrinkles. From the visual perspective, there will be shadows, an that is dark circles.
