Final answer:

Hyperpigmentation is the darkening of the skin due to an increase in melanin production. Sun exposure, hormonal changes, and inflammation/injury are common causes. Consult a dermatologist for accurate diagnosis and treatment.

Step-by-step explanation:

Hyperpigmentation is the darkening of the skin due to an increase in the production of melanin, the pigment responsible for skin color. There are several causes of hyperpigmentation, including:

  • Sun exposure: Exposure to UV radiation stimulates the production of melanin, leading to tanning and hyperpigmentation.
  • Hormonal changes: Conditions such as Addison's disease and pregnancy can cause an overproduction of melanin, resulting in hyperpigmentation.
  • Inflammation and injury: Skin inflammation and trauma can trigger melanocyte activity, leading to hyperpigmentation.

It's important to note that hyperpigmentation can sometimes be a manifestation of an underlying medical condition, so it's best to consult a dermatologist for an accurate diagnosis and appropriate treatment.
