Treatment for post inflammatory erythema

Post-inflammatory erythema is a flat red or pink mark left after inflammation has settled. Acne is a common cause, but irritation, injury, or another rash can also leave redness. The colour comes from changes in small surface blood vessels, so it is different from brown post-inflammatory hyperpigmentation and from a raised or indented scar.

The mark may look stronger after heat, exercise, or washing. New pimples or ongoing irritation can keep adding fresh areas, which is why treating active acne matters alongside any plan for established redness.

Cleanse gently, moisturise, and use sunscreen each day. Avoid squeezing spots, harsh exfoliation, fragranced products, and repeated changes to your routine. A dermatologist may discuss acne treatment first, then options such as IPL photofacial or pulsed dye laser treatment for persistent visible redness. Treatment choice depends on the diagnosis, skin tone, sensitivity, and whether the redness is still changing.

Arrange an assessment if redness is spreading, painful, warm, itchy, scaly, or associated with pus, swelling, or new lesions. Seek prompt care for facial swelling, eye symptoms, breathing difficulty, or a rapidly changing rash. A mark that bleeds, ulcerates, becomes firm, or looks unlike your other marks should be examined rather than treated cosmetically.

Ask whether the colour is erythema, pigmentation, or scarring; whether acne is still active; and which skincare ingredients are least irritating. If considering a device, ask which technology fits your skin tone, expected recovery, and signs of a treatment reaction.
