Skin pigmentation commonly occurs when melanin is overproduced in certain exposed spots on the skin. This results in dark patches on the skin that have been exposed to sunlight. Common causes Melasma or chloasma can also occur as a result of hormonal influences such as pregnancy and menopause.
Skin pigmentation is common in both men and women. However, people with darker skin tones are more prone to hyperpigmentation, especially with prolonged sun exposure.
Most forms of skin pigmentation are caused by an excess production of melanin. Hyperpigmentation can affect exposed areas of skin including the face and the back of the hands.
