How common is uneven skin tone in post-inflammatory hyperpigmentation?

Inflammation can signal pigment-producing cells to release more pigment. The mark may be brown, grey-brown, or deeper in colour than nearby skin, depending on the depth of pigment and the person’s natural skin tone. It may sit exactly where the original irritation was, and new inflammation can leave additional uneven areas.

Treat the underlying trigger with appropriate medical advice and avoid scratching, squeezing, or harsh exfoliation. Protect exposed skin from sunlight because light can deepen contrast. A dermatologist may suggest a calming routine, pigment-targeted treatment, or a procedure after the skin is stable; treatment choice depends on the cause, location, and skin type.

Seek care if inflammation is frequent, spreading, infected-looking, or difficult to control. Have a mark checked if it appears without a preceding skin problem, changes independently, becomes painful, bleeds, or develops scale. A review is also useful when pigmentation is persistent or causing significant distress.

Ask what caused the inflammation, whether it is still active, and how to prevent new marks. Discuss suitable sunscreen, products to avoid, treatment timing, possible irritation, and what change would mean you should stop a product and return for review.
