GlossaryPost-Inflammatory Hyperpigmentation

skin darkens after inflammation due to excess melanin production

Post-Inflammatory Hyperpigmentation (PIH) is a condition where the skin becomes darker in color after an inflammatory event, such as acne, eczema, or a skin injury. This occurs because the inflammation triggers an overproduction of melanin, the pigment responsible for skin color, leading to dark spots or patches that can persist even after the initial inflammation has healed.
