What causes dark pigmentation on skin?
The color of the human’s derma depends on the pigment concentration. The lack or excess of melanin, carotene and other hormones leads to appearance of dark spots of different color and size. Stained areas of the skin can be congenital or appear with age. Often they are generated by ultraviolet impact – when sunbathing in the sun or in a solarium. This is due to the fact that melanin, giving a brown color, protects the skin from the effects of ultraviolet radiation. The more ultraviolet radiation gets on the skin, the more melanin is produced.
There are many other reasons for such spots on the face and body. Sometimes is caused by serious health disorders. Therefore, noticing the new makrs on your derma you have to seek doctor’s advice.
Pigment production is enhanced by:
- Natural and premature aging.
- Hormonal problems associated with thyroid gland diseases, tumors of the pituitary gland.
- Diseases of the liver.
- Neuropsychiatric disorders.
- Vitamin deficiency, metabolic disorders.
- Gynecological disorders.
Also it can be provoked by drugs intake and cosmetics. Also, dark spots can appear during pregnancy.
Do not confuse dark stains and malignant tumors – these are completely different issues. The unusual stains can be left or removed, and in both cases it will not affect the overall health, however oncological formations require a long, serious treatment.
Theoretically, such developments on your derma can appear at any age.
However, if the derma color change is observed in young people then it is usually caused by hormonal changes related to pregnancy, to the prolonged use of certain contraceptives, to the cosmetics of poor quality or to the intake of certain medicines.
The most common cause of the pigmentation is aging: at the age of forty – fifty years and older people often complain that more marks appear on the derma surface.
Why is this happening?
Basically, it is because the cells gradually lose the ability to interrupt the pigment production. Also, hormonal imbalance in women during menopause can worsen the situation.
So, dark spots appear quite often in case of:
- gynecological diseases (dysfunctions of ovaries, inflammatory processes) and pregnancy;
- liver diseases;
- hormonal contraceptives administration;
- chronic inflammatory processes in the genitourinary tract;
- thyroid dysfunction;
- liver or bile ducts disorder;
- nervous disorder, when a person is weakened by chronic diseases, of for example working with chemicals;
- vitamin C deficiency;
- introduction of various substances into the skin (this can happen in case of accidents: gunpowder from a gunshot, graphite or coal during the mine collapse);
- highly irritating ointments and creams application;
- injuries: after popping acne, uncontrolled use of local caustic agents used for any neoplasms removal.
