What should you know about post inflammatory hyperpigmentation red?

Post-inflammatory hyperpigmentation is commonly described as a brown or darker mark, but a healing area can also look red, pink, or reddish-brown. This can happen after acne, eczema flare-ups, scratching, picking, irritation, or a minor skin injury. The colour, texture, location, and timing matter: a flat mark is different from a raised or tender lesion. Redness that is warm, spreading, swollen, or painful may signal ongoing inflammation rather than a settled mark.

Avoid picking, scrubbing, fragranced irritants, and unplanned bleaching products. Use a bland moisturiser, keep the area protected from sunlight, and address any active acne or dermatitis with suitable medical guidance. A dermatologist can decide whether the change is mainly redness, pigment, or both. Depending on the finding, options may include a chemical peel, a skin brightening treatment, or picosecond laser treatment; these procedures need careful selection when skin is still inflamed.

Arrange a clinical review if the mark is enlarging, increasingly painful, hot, crusted, oozing, bleeding, or associated with a new rash. Seek prompt advice when redness follows a procedure or product and comes with swelling, blisters, or marked burning. A persistent or changing patch deserves examination so another cause is not mistaken for post-inflammatory change.

Ask whether the colour is due to pigment, redness, or active inflammation; what triggered it; which products should be paused; and whether treatment should wait until the skin barrier has settled.
