Hyperpigmentation

Resource #1:
"Hyperpigmentation is a common, usually harmless condition in which patches of skin become darker in color than the normal surrounding skin.

This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.

Hyperpigmentation can affect the skin color of people of any race."

Resource #2:
"Increased melanin deposition resulting in hyperpigmentation may be caused by hormonal changes (eg, in Addison's disease, pregnancy, or anovular pill use).

Hyperpigmentation may also result from iron deposition in hemochromatosis or from silver deposits (eg, in argyria). Long-term application (years) of hydroquinone is a rare cause of local ochronosis.

Exposure to sunlight accentuates skin pigmentation.
