What is Post-Inflammatory Erythema (PIE) in Acne?
Post-inflammatory erythema (PIE) refers to the persistent red, pink, or purple marks that remain on the skin after acne breakouts have healed. While PIE typically resolves on its own, utilizing dermatological treatments can accelerate the healing process. Additionally, certain at-home remedies may also aid in diminishing or completely removing PIE.
