post-inflammatory erythema: Definition, Uses, and Clinical Overview
post-inflammatory erythema is a persistent pink, red, or purplish discoloration that remains after skin inflammation has improved. It reflects changes in superficial blood vessels and blood flow rather than extra pigment. It is commonly discussed in cosmetic dermatology, acne care, and post-procedure follow-up. It can also appear after reconstructive or traumatic skin injury when healing leaves visible redness.
