periorbital pigmentation
Introduction
Introduction to periorbital pigmentation Periorbital pigmentation is also known as "black skin disease around the eyelids", commonly known as "black circles." Periorbital pigmentation is due to frequent day and night, emotional instability, eye fatigue, aging, venous blood flow velocity is too slow, eye skin red blood cells are insufficient oxygen supply, excessive accumulation of carbon dioxide and metabolic waste in venous blood vessels, forming chronic deficiency Oxygen, blood is dark and stagnates and causes hyperpigmentation of the eye. basic knowledge The proportion of illness: the incidence rate is about 0.007%-0.008% Susceptible people: no specific population Mode of infection: non-infectious Complications: eye disease
Cause
Periorbital pigmentation etiology
Genetic (35%):
Genetic constitution and physiological structure, when the skin around the eyelid is particularly thin, and the subcutaneous tissue is particularly small, when the blood flows through the large vein here, it is convenient to appear blue-black dizziness under the surface layer of the skin, which is called dark circles.
Sleep (25%):
Insufficient sleep, excessive fatigue, so that the eyelids can not get rest, in a state of tension and contraction, the blood flow of this part increases for a long time, causing the blood vessels in the subcutaneous tissue of the eye circle to fill, resulting in congestion of the eye circles and stagnation of dark shadows.
Irregular menstruation (15%):
Women with irregular menstruation, functional uterine bleeding, primary dysmenorrhea, early menstruation, late menstruation, long menstrual period, excessive menstruation, late pregnancy, old age, etc., dark circles will also deepen, others include The use of genetics and cosmetics is excessive, which causes the penetration of pigment particles, as well as excessive sexual intercourse, which can lead to the production of dark circles.
Kidney loss, long-term illness (5%):
Kidney gas loss, so that the two eyes lack the moisture of the essence, so that the black floats on the top, so the eye circles are black. For those who have been sick for a long time or have a serious illness, the skin is prone to pigmentation due to weak subcutaneous tissue around the eye, and it is easy to appear on the upper and lower eyelids, and a black circle appears.
Prevention
Periorbital pigmentation prevention
1. Avoid contact with harmful chemicals, and do a good job in occupational disease prevention and labor protection.
2. Avoid local irritation of established pigments, including scratching, rubbing and smearing chemicals.
3. Active treatment of the primary disease, with the improvement of the condition of the primary disease, the pigment will be reduced.
4. Remember to use all appropriate eye makeup remover to completely remove all eye makeup, including waterproof mascara. Misuse of improper makeup removers can cause sensation of discomfort.
5. The skin around the eyes does not have oil glands. It is one of the most vulnerable parts of the body. The degree of slimness is not inconsistent with the airmail envelope. Care should be taken.
6. Using an overweight eye cream will make your eyes look puffy when you get up early in the morning, so choose a softer eye cream or gel.
Complication
Periorbital pigmentation complications Complications
The blood flow in the area increases for a long time, causing the blood vessels in the subcutaneous tissue of the eye circle to fill, which causes the eye circles to become bloody. There is no corresponding organic disease in the disease, which will affect the appearance and may cause certain psychological stress to the patient.
Symptom

Pigmentation spots are present after birth. As the age increases, the pigment gradually deepens, the number increases, and the area expands. It is a brown or dark brown pigmentation with inter-island-like normal skin. Invasion of the whole body skin including the palmar, oral and vulvar mucosa and conjunctiva can be involved. Generally, after puberty, the disease develops slowly and gradually, but there is no self-healing tendency.
Examine
Periorbital pigmentation examination
Onset in children, manifested as periorbital pigmentation. Generally, the lower eyelids are involved first, and the upper eyelids may be involved, and may extend to the eyebrows and the shins as the age increases. Biopsy showed that the skin around the eyelids had obvious pigmentation and the number of pigment cells was significantly increased, but it was not shaped. Local tissues also have infiltration of monocytes and eosinophils.
Diagnosis
Diagnosis of periorbital pigmentation
First, we must exclude exogenous factors. Pigmentation caused by chemicals and cosmetics mostly occurs at the contact site (or exposed site), and there may be a history of contact with such substances; the pigmentation caused by drug-induced causes is mostly systemic, and the history of taking the corresponding drugs can be found. . Medical history can often provide the main clues. Pigmentation begins in young years and has similar manifestations in family members. It should be considered congenital, hereditary disease; after adulthood, consider various physical and chemical factors, so the history of occupational history and medical treatment is also very Important; then consider whether there are various pigmentation caused by chronic skin diseases, such patients often have a long history of skin; finally consider systemic chronic diseases, pay special attention to chronic liver disease, pituitary, adrenal function Decreased, Cushing's disease, hemochromatosis, hematoporphyria, and connective tissue diseases. Skin pigmentation of systemic chronic diseases is only one of its clinical manifestations. They often have a long history and have other corresponding clinical manifestations. It is not difficult to identify them carefully.
