Key Takeaways

• Post-inflammatory erythema (PIE) is the red or pink discoloration left on the skin after an acne breakout heals.
• PIE is caused by dilated blood vessels beneath the skin’s surface, not by excess melanin.
• Without treatment, PIE can linger anywhere from three months to over two years.
• PIE looks and behaves differently from post-inflammatory hyperpigmentation (PIH), and requires a different treatment approach.
• Professional treatments at Tru Glō Medspa, including BBL and Sylfirm RF, target the vascular source of PIE directly.
• A consultation helps identify which treatment is the right fit for your skin tone and the severity of your marks.
