Vitamin C for Post-Inflammatory Erythema: What to Know

Post-inflammatory erythema means lingering red or pink marks after skin inflammation has settled. It can follow [Acne](/conditions/acne/) or another irritated process. Vitamin C may provide antioxidant support and improve the general appearance of uneven tone, but it does not directly remove every visible blood-vessel change. Redness can also look worse when skin is hot, rubbed, dry, or irritated.

Use a gentle cleanser, moisturiser, and daily broad-spectrum sunscreen. If you try vitamin C, choose one product, apply it as directed, and introduce it slowly; stop if stinging, burning, swelling, or increased redness appears. Avoid picking and harsh scrubs while the skin barrier recovers. A dermatologist may discuss [IPL Photofacial](/treatments/laser-and-energy/ipl-photofacial/) or [Pulsed Dye Laser Treatment](/treatments/laser-and-energy/pulsed-dye-laser-treatment/) for selected persistent redness.

Arrange assessment if redness is painful, hot, spreading, accompanied by pus or fever, or not settling after the original inflammation improves. Seek prompt help for facial swelling, blistering, or breathing difficulty after skincare. Ongoing flushing, burning, or recurrent bumps may point to a different condition and should be examined.

Is this post-inflammatory erythema or another cause of redness? Would vitamin C calm or irritate my skin? What sunscreen and moisturiser should I use? Am I a candidate for IPL or pulsed dye laser treatment?
