post-inflammatory hyperpigmentation
Post-inflammatory hyperpigmentation (PIH) is a skin condition characterized by darkened patches that develop after an injury or inflammation to the skin. This can occur due to various factors, including acne, eczema, or even minor cuts. The skin produces excess melanin, the pigment responsible for skin color, in response to the inflammation, leading to these darker areas.
PIH is more common in individuals with darker skin tones, as they have more active melanin production. While it is not harmful, it can be a cosmetic concern for many. Treatment options include topical creams, chemical peels, and laser therapy to help reduce the appearance of the dark spots.
