What should you know about dermal post inflammatory hyperpigmentation?

Inflammation from acne, eczema, a rash, burns, or a procedure can stimulate pigment production. The mark may remain after the original problem has settled and can look brown, grey, or darker than surrounding skin. Dermal pigment lies deeper and may fade slowly. Learn more about [Post-Inflammatory Hyperpigmentation](/conditions/post-inflammatory-hyperpigmentation/), [Acne](/conditions/acne/), and [Atopic Dermatitis](/conditions/atopic-dermatitis/).

Control active inflammation first and avoid scratching, squeezing, harsh scrubs, or unplanned combinations of strong products. Use daily broad-spectrum sunscreen and cover the area when outdoors. A dermatologist may consider [Skin Brightening Treatment](/treatments/aesthetic-procedures/skin-brightening-treatment/), [Chemical Peel](/treatments/aesthetic-procedures/chemical-peel/), or [Picosecond Laser Treatment](/treatments/laser-and-energy/picosecond-laser-treatment/) after assessing depth and skin tone. Irritation can create more pigment, so treatment should progress carefully.

Seek assessment if the original rash or acne is not settling, marks keep appearing without a clear trigger, or a patch is changing, painful, bleeding, or crusting. After treatment, contact the clinic about worsening pain, blistering, swelling, or persistent redness. These features may signal irritation or another skin problem.

Ask which inflammation caused the mark, whether the pigment is dermal or mixed, which products are suitable for your skin, and how to prevent new marks. Mention recent procedures, medicines, pregnancy, breastfeeding, and any tendency to scar or darken after injury.
