2024年3月11日 · Hyperpigmentation occurs when skin cells produce too much melanin, the protein pigment that colors our skin and hair. This may occur due to hereditary factors, medical conditions, medications, and external influences. Common …

Hyperpigmentation has multiple causes and may be focal or diffuse. Most cases are due to an increase in melanin production and deposition. (See also Overview of Pigmentation Disorders.) Focal hyperpigmentation is most often postinflammatory in nature, occurring after injury (eg, cuts and burns) or other causes of inflammation (eg, acne, lupus).

2024年7月18日 · Hyperpigmentation occurs when darker patches appear on the skin. Causes include age spots, melasma, and skin inflammation. Learn about why it happens and how to reduce it.

2022年4月26日 · What Causes Hyperpigmentation? Hyperpigmentation results when internal or external stimuli such as UV exposure, skin injury, infection or inflammation stimulate melanin-producing cells called melanocytes found inside melanosomes. The basic function of melanocytes is to produce melanin.

2024年9月12日 · Hyperpigmentation develops when melanocytes—specialized skin cells responsible for producing melanin —start producing more melanin than usual. Overactive melanocytes and increased melanin can lead to dark spots or patches on the skin. Several factors can contribute to the development of hyperpigmented skin, including:

2022年1月4日 · Hyperpigmentation refers to patches of skin that are darker than the surrounding area; Sun exposure and inflammation are the leading causes; Darker skin tones are most affected by hyperpigmentation; Several treatments are available and will depend upon cause and skin tone

Some cases of hyperpigmentation are caused not by melanin but by other pigmented substances that are not normally present in the skin. Diseases such as hemochromatosis or hemosiderosis, which are caused by too much iron in the body, can cause hyperpigmentation.

2024年7月29日 · Hyperpigmentation is more common in darker skin tones because they have more melanin. Many things can cause too much melanin, like sun damage, hormonal changes, and injuries. This leads to dark spots, age spots, melasma, and more. We will look into hyperpigmentation’s types, causes, and treatments.
