Post-inflammatory hyperpigmentation treatment: what to know

After acne, eczema, bites, burns, shaving irritation, or another injury settles, the skin can continue producing extra pigment at the affected site. The mark may be brown, grey, or darker than the surrounding skin. Ongoing scratching or inflammation can keep the process active, so treating only the colour may disappoint. A clinician can distinguish post-inflammatory change from melasma, a fungal problem, a mole, or another condition. See [Dark Patches On Skin](/symptoms/dark-patches-on-skin/) for related symptoms.

Stop picking and use a simple, non-irritating routine while the original problem is treated. Protect exposed areas from sunlight and follow the prescribed plan rather than combining several brightening products. Depending on location and skin response, options may include [Hydroquinone Treatment](/treatments/medical-dermatology/topical-hydroquinone-therapy/), [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), or [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/). Procedures should be selected cautiously because new irritation can create more pigment.

Book a review if the original rash keeps returning, the mark spreads without a clear trigger, or the area becomes itchy, painful, scaly, crusted, or tender. Seek prompt assessment for bleeding, an open sore, a rapidly changing spot, or signs of infection such as pus and worsening warmth. A persistent mark that has not been diagnosed should not be treated purely for appearance.

Ask what caused the inflammation, how to prevent another flare, which treatment fits your skin tone and body site, and how to recognise irritation from treatment. Ask when to stop a product and when progress should be reassessed.
