hyperpigmentation

Hyperpigmentation is a condition characterized by the darkening of an area of the skin or nails due to an excess production of melanin, the pigment responsible for skin color. This increase in melanin can result from a variety of factors, including sun exposure, inflammation, trauma, certain medications, or underlying medical conditions.

Hyperpigmentation is associated with numerous dermatological disorders and can present in various forms, such as melasma, post-inflammatory hyperpigmentation, and lentigines. It tends to be more prevalent and persistent in individuals with darker skin tones, who have more active melanocytes and are thus more prone to uneven pigmentation.
