What is hyperpigmentation?
Hyperpigmentation occurs when the skin produces more melanin, the pigment that gives skin its color. This can make spots or patches of skin appear darker than surrounding areas.
Hyperpigmentation is a common skin condition. It affects people of all skin types.
Some forms of hyperpigmentation, including melasma and sun spots, are more likely to affect areas of skin that face sun exposure, including the face, arms, and legs.
Other types of hyperpigmentation form after an injury or skin inflammation, such as cuts, burns, acne, or lupus. These can occur anywhere on the body.
Having extra pigment in some areas of skin is usually harmless but can sometimes indicate another medical condition.
