Dark areas appearing on the skin are the main symptom of hyperpigmentation, which can vary in size and anywhere on the body.

Pregnancy changes hormone levels in the body and this can also be a factor in the production of melanin in women. A rare endocrine disease such as Addison's disease: This can produce hyperpigmentation that is most apparent in sun-exposed areas, such as the face, neck, and hands; or areas of high friction, like elbows and knees.
