What are the treatment options for post-inflammatory erythema?

Post-inflammatory erythema is a red, pink, or sometimes purplish mark that remains after acne, a rash, a bite, or another source of inflammation has settled. It reflects altered small blood vessels and ongoing sensitivity rather than a new infection. Marks may look more obvious after heat, exercise, or sun exposure. Redness is different from post-inflammatory hyperpigmentation, which appears brown or grey, so the distinction affects treatment choice.

Treat active acne or irritation gently so new inflammation does not create additional marks. Use a broad-spectrum sunscreen and avoid picking, scrubbing, fragranced products, and unnecessary heat on the area. If redness remains, an [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/) may target visible colour across a broader area. A [Pulsed Dye Laser Treatment](/treatments/laser-and-energy/pulsed-dye-laser-treatment/) delivers focused light to blood vessels and may suit selected persistent red marks. A clinician should assess skin tone, recent tanning, medicines, and the original cause before treatment.

Arrange an assessment if redness is painful, warm, swollen, spreading, draining, or accompanied by fever. Seek advice if marks appear without a preceding skin problem, bleed, ulcerate, or change rapidly. Prompt review is also sensible when redness follows a procedure and becomes increasingly tender rather than gradually settling.

Is this redness post-inflammatory erythema or pigmentation? Is the original acne or irritation fully controlled? Would IPL or pulsed dye laser treatment suit my skin tone and mark pattern? What sun and skincare precautions are needed before and after treatment?
