Post-Inflammatory Hyperpigmentation (PIH) is arguably the most common and pervasive hyperpigmentation disorder in India. PIH occurs following any form of skin inflammation or injury, with the most frequent causes being acne, eczema, insect bites, or aggressive cosmetic procedures. The high prevalence of active acne among adolescents and young adults, coupled with the tendency of darker skin to produce excessive melanin in response to trauma, ensures PIH remains a primary concern for dermatologists.

Effective treatment of PIH requires a two-pronged strategy: first, urgently resolving the underlying inflammatory condition (e.g., treating the active acne), and second, carefully fading the resulting dark spots. Treatment protocols frequently involve gentle exfoliation (using salicylic or azelaic acid), pigment inhibitors (like hydroquinone or alpha arbutin), and non-aggressive procedures. The challenge lies in utilizing treatments strong enough to fade the pigment without causing further inflammation, which would restart the PIH cycle. The high incidence of PIH drives continuous research into safer, anti-inflammatory depigmenting agents specifically formulated for Fitzpatrick skin types IV-VI. This clinical focus is paramount, as indicated in the Dermatology Solutions Analysis.

FAQ

Q: What is the most common underlying cause of Post-Inflammatory Hyperpigmentation (PIH) in Indian youth? A: The most common underlying cause is acne vulgaris, where the inflammation and trauma from active pimples or picking trigger the excessive production and deposition of melanin after the lesion heals.

Q: Why must PIH treatment be gentle and non-aggressive? A: PIH is a reaction to inflammation; therefore, using treatments that cause further irritation or trauma (such as high-concentration peels or overly aggressive lasers) will simply worsen the existing pigmentation, leading to a chronic cycle of discoloration.
