What is the darkening of the ?
Darkening of the skin or hyperpigmentation is the appearance of skin spots that are darker than the adjacent skin. Hyperpigmentation can also spread to the entire skin.
Skin discoloration in hyperpigmentation occurs when the production of melanin (a pigment normally found in the skin) increases and darkens due to its accumulation.
Dark skin is found in all races. Melasma is the hyperpigmentation of sun-exposed surfaces in completely black people. Dark areas of the skin are usually seen as relatively small spots, also called moles. Moles can be caused by sunlight and the accumulation of skin damage over many years.
The energy of the sun's ultraviolet rays is absorbed by melanin to prevent skin damage. This, in turn, can darken areas of hyperpigmentation.
In some cases, dark skin is caused by hormonal changes (for example, during pregnancy or by taking birth control pills) or by certain disorders and diseases such as caffeolite macules. Dark skin, including dark or light brown spots, is sometimes present on the skin from birth. Addison's disease (in which hormones secreted by the adrenal glands are reduced) can sometimes cause darkening of the skin.
Dark skin can also be caused by a combination of factors such as sun exposure or allergic reactions to certain plant or chemical substances. In some cases, such as during pregnancy or the use of birth control pills, the skin darkens temporarily.
Sometimes hyperpigmentation can be treated effectively with medication or laser. Some cases of hyperpigmentation can also be reduced by changing medications and circulating hormone levels.
Dark skin is usually safe, but in some cases it can indicate a serious illness that needs treatment. If your skin is dark and you feel tired, loss of appetite or sudden depression. Or if, in addition to the skin, the mucous membranes of your mouth and other mucous membranes are also darkened. Or if you have constipation or diarrhea, be sure to see a doctor.
