Post-Inflammatory Hyperpigmentation

Post-Inflammatory Hyperpigmentation (Post-Inflammatory Hyperpigmentation), commonly known as PIH, is a skin condition characterized by darkened patches or spots that appear after skin inflammation or injury. It commonly develops following acne, eczema, burns, allergic reactions, or cosmetic procedures such as chemical peels and laser treatments. PIH occurs when excess melanin is produced or unevenly distributed during the skin’s healing process, leading to discoloration.

This condition can affect all skin types but is more common and often more noticeable in individuals with darker skin tones. The pigmentation may range from light brown to deep gray or black, depending on skin tone and the depth of pigment deposition. While PIH is not harmful or contagious, it can impact self-confidence and overall skin appearance.

Treatment options focus on reducing pigmentation and preventing further darkening. Common approaches include topical agents like Hydroquinone, retinoids, Vitamin C, and chemical exfoliants. Dermatological procedures such as chemical peels, microdermabrasion, and laser therapy may also help in stubborn cases. Early treatment and proper skincare can significantly improve outcomes.
