🧬 PIH Hub – Clinical Guide to Post-Inflammatory Hyperpigmentation
Post-Inflammatory Hyperpigmentation (PIH) is a skin condition where dark marks remain after inflammation such as acne, irritation, or injury.
This hub brings together clinical insights about PIH, including how it forms, why it lasts, and how it should be treated correctly.
🧠Understanding PIH
PIH is not a disease. It is a biological response of the skin after inflammation.
It involves:
melanocyte activation
inflammation response
skin barrier disruption
UV influence

🧬 Clinical Insight
PIH severity and duration depend on:
inflammation level
skin barrier health
UV exposure
depth of pigment
skin type and melanocyte activity
consistency of treatment approach
✨ Key Takeaway
PIH is not just surface pigmentation. It is the result of an ongoing inflammatory and biological process inside the skin.
Correct management requires understanding the skin system, not just treating spots.
