Does post-inflammatory hyperpigmentation cause uneven skin tone?

Post-inflammatory hyperpigmentation is a colour change that can follow acne, eczema, a rash, a cut, a burn, or another irritated area. The affected skin may look brown, grey, or darker than the surrounding skin, especially after the original problem has improved. Uneven Skin Tone is a very common presentation of Post-Inflammatory Hyperpigmentation. The mark is not contagious, and its appearance does not by itself show whether the earlier inflammation was mild or severe.

Treat the active source of irritation gently and avoid picking, scrubbing, or repeatedly rubbing the area. Daily broad-spectrum sun protection can reduce further darkening, particularly on exposed skin. A clinician may suggest a topical product after checking the location, skin sensitivity, and likely cause; some ingredients can irritate skin and deepen colour when used incorrectly. Take clear photographs in consistent lighting so changes can be followed over time. Improvement can be gradual, and the plan may need adjustment if new inflammation keeps appearing.

Arrange a dermatology assessment if the colour change is spreading, repeatedly returning, itchy, painful, scaly, bleeding, or changing in a way that does not match the original skin problem. Seek prompt care for a rapidly changing spot, an open sore that does not heal, or marked swelling. These features need assessment rather than assuming that every dark mark is post-inflammatory pigmentation.

Ask what earlier inflammation may have triggered the colour change, whether the pattern fits post-inflammatory hyperpigmentation, and which products are suitable for your skin. You can also ask how to prevent new marks, how long a review should take, and which changes should prompt an earlier appointment.
