Are your acne scars red or dark brown? Treating them requires completely different dermatological actives. Discover the definitive guide to PIE vs PIH in India.
When a pimple heals, it often leaves a stubborn flat mark. However, treating it effectively requires identifying whether it is PIE (Post-Inflammatory Erythema - damaged red/pink micro-capillaries) or PIH (Post-Inflammatory Hyperpigmentation - excess melanin deposits). Using tyrosinase inhibitors on vascular redness won’t work, while soothing agents alone won’t break down melanin polymers.

Tips for Fading Red and Brown Acne Marks
- The Glass Test: Press a clear glass cup firmly against the red mark. If it disappears temporarily (blanches), it is PIE (vascular). If it stays dark brown, it is PIH (melanin).
- Target PIE with Niacinamide: Apply Minimalist 10% Niacinamide twice daily to repair capillary inflammation.
- Strict Morning Sunscreen: UV radiation turns red PIE marks into permanent brown PIH patches. Always protect with Minimalist SPF 50.
Frequently Asked Questions
Which takes longer to heal, PIE or PIH?
PIE (red marks) typically fades in 4 to 8 weeks with barrier care. PIH (deep brown spots) can take 3 to 6 months because melanin must be shed through complete cellular turnover.
Can you have both PIE and PIH together?
Yes, on South Asian skin tones, an acne lesion frequently begins as vascular redness (PIE) that stimulates melanocytes to deposit dark pigment (PIH) over subsequent weeks.
