Hyperpigmentation … a skin condition that requires careful and specialized care!
You may notice some brown or dark spots on the surface of the skin and wonder about the causes of these spots … It is hyperpigmentation that can affect the skin as a result of many factors, most notably exposure to the sun, which affects the pigment cells in the body. What is hyperpigmentation? What are the most prominent causes? How is it diagnosed? What are the methods used to treat it?
What is hyperpigmentation?
Hyperpigmentation is a skin condition that causes dark spots to appear on the skin. It can be concentrated in one area of the body or spread across various parts. These spots appear especially on the areas most exposed to the sun, such as the face and hands, but they can also appear on the back and other parts of the body. In most cases, the sun is the most influential factor in this condition, which leads to an overproduction of melanin in the body by the melanocytes.
In some cases, hyperpigmentation appears from birth, like Nevus of Ota or coffee milk spots; In other cases, this condition appears at a certain stage of life like the case of acne or skin lesions.
What is the role of pigment cells in the body?
Melanocytes produce a brown pigment known as melanin which is responsible for determining the color of skin, hair and eyes in the body. When these cells are exposed to excessive sunlight, they secrete more melanin, which in turn leads to the darkening of the skin, turning it brown or dark. The interaction of these cells with the body varies according to the color of the skin, whether it is white or brown. This overproduction of melanin is responsible for hyperpigmentation.
What are the causes of hyperpigmentation?
The overproduction of melanin in the body is the main cause of hyperpigmentation, but other causes can lead to this condition, including:
- Hormonal disorders are one of the causes that lead to hyperpigmentation, as the pigment cells are affected by these changes. This may also occur as a result of following a certain hormonal treatment.
- Excessive exposure to sunlight is also responsible for hyperpigmentation, as sunlight affects melanin in the body and causes dark spots to appear, especially if skin protection is not provided.
- Some medications affect the activity of pigment cells in the body, similar to antidepressants that may cause gray spots to appear on the skin.
- Dermatitis is also responsible for hyperpigmentation as a result of the great damage that may be caused to the skin, which leads to the appearance of dark spots.
- Some diseases can also be responsible for hyperpigmentation, such as Addison’s disease, which is caused by a defect in the adrenal gland, or hemochromatosis, which causes a high concentration of iron in the blood.
What are the influencing factors that cause hyperpigmentation?
Skin can be affected greatly and quickly by external factors, in addition to being severely affected by physical health conditions.
Hyperpigmentation can appear as a result of many influencing factors, most notably:
- Sun exposure is the most prominent factor that directly affects the skin. It activates the pigment cells and increases the production of melanin, causing hyperpigmentation.
- Among the influencing factors is the color of the skin itself, as people with darker skin are more likely to suffer from hyperpigmentation than those with lighter skin tone.
- Infections or skin diseases also affect pigment cells and increase melanin production.
- Pregnancy may also cause hyperpigmentation, especially since some pregnant women suffer from melasma during pregnancy. On the other hand, oral contraceptives also play a role in hyperpigmentation, as they affect body hormones.
- Wounds and burns that affect the skin can be one of the factors causing hyperpigmentation. Pigment cells activate and increase melanin production to heal wounds, burns and skin damage.
What are the types of hyperpigmentation?
It is possible to distinguish between different types of hyperpigmentation, depending on the causes that lead to this condition. The types are divided as follows:
This type of hyperpigmentation results from injuries and inflammations the skin is exposed to, in addition to the body’s reaction to sunlight, as well as from abnormal skin tags.

Melasma, a type of hyperpigmentation, is most often associated with pregnancy, but other conditions may lead to melasma. It is a grayish patch of skin that appears particularly on the face, neck and hands. Melasma may appear in pregnant women or those with brown skin in particular.
As the name indicates, this type of hyperpigmentation is associated with severe skin diseases and infections such as eczema, and it leads to the appearance of dark skin patches on some parts of the body, especially the face and neck.
This type of hyperpigmentation is caused by certain medications, antidepressants, antibiotics and chemotherapy. It leads to the appearance of dark spots on a large area of the skin. The color of the spots varies between violet, black, blue, brown and gray.
