Have you ever noticed dark spots lingering on your skin after a rash, pimple, or injury has healed? This common condition is called post-inflammatory hyperpigmentation (PIH). While harmless, these spots can be frustrating and take months to fade. Let’s explore what PIH is, why it happens, and how to treat it.
What Is Post-Inflammatory Hyperpigmentation?
PIH occurs when the skin produces excess melanin (the pigment that gives skin its color) in response to inflammation or injury. This leads to darkened patches that can appear anywhere on the body. PIH is more common in darker skin tones but can affect anyone.
Why Does PIH Happen?
When the skin experiences inflammation—from acne, eczema, insect bites, burns, or even skin procedures—it triggers melanocytes (pigment-producing cells) to produce extra melanin. This excess pigment deposits in the skin, leading to brown, tan, or even blue-gray discoloration. Unlike true scars, PIH does not involve a change in skin texture, just color.
How Can You Treat PIH?
PIH often fades on its own, but this can take months or even years without treatment. The good news? Several treatments can help:
• Sun Protection – UV exposure worsens PIH, so daily SPF 30+ sunscreen is essential.
• Topical Brightening Agents – Ingredients like hydroquinone, niacinamide, vitamin C, and kojic acid can help lighten dark spots.
• Retinoids – Tretinoin or retinol speed up skin cell turnover, helping to fade pigmentation faster.
• Chemical Peels – Professional peels with glycolic acid, salicylic acid, or trichloroacetic acid (TCA) can improve pigmentation.
• Laser Treatments – Certain lasers, such as picosecond or fractional lasers, can target pigment without harming surrounding skin.
Preventing PIH
If you’re prone to PIH, the best approach is prevention. Avoid picking at acne or scabs, treat inflammation early, and always wear sunscreen.
If you’re struggling with persistent PIH, a dermatologist can create a personalized treatment plan to help you achieve clearer, more even-toned skin.
