Hyperpigmentation

Also known as: Skin darkening, melasma (one type)

Medically reviewed, last updated

Hyperpigmentation is the darkening of skin caused by excess melanin production. It includes melasma (hormonally driven patches, often on the face), post-inflammatory hyperpigmentation (PIH) following acne, eczema, or injury, and sun-induced dark spots. On skin of color, hyperpigmentation is one of the most common dermatologic concerns and often persists longer than the original inflammatory event.

Treatment typically combines a prescription-strength regimen (tretinoin, hydroquinone, azelaic acid) with rigorous sun protection. Over-the-counter products usually under-perform on Black skin because of pigment depth. See our Apostrophe review for skin-of-color treatment options.
