Post-Inflammatory Erythema vs Hyperpigmentation
Have you ever noticed persistent redness or dark spots on your skin after a breakout or injury? These marks are likely either post-inflammatory erythema (PIE) or post-inflammatory hyperpigmentation (PIH). While both are common skin concerns, they have distinct characteristics and require different approaches for treatment.
Post-Inflammatory Erythema (PIE)
PIE is characterized by pink or red marks that appear after skin inflammation, typically following acne lesions or other skin injuries. This occurs when small blood vessels near the surface of the skin dilate in response to trauma. PIE is more common in individuals with fair to light skin tones.
Key features of PIE:
- Appears as pink or red marks
- More common in lighter skin tones
- Often circular in shape
- Temporarily blanches (turns white) when pressed
Post-Inflammatory Hyperpigmentation (PIH)
PIH, on the other hand, presents as brown, gray, or black marks on the skin. It results from an overproduction of melanin during the skin's healing process. PIH is more prevalent in individuals with medium to dark skin tones.
Key features of PIH:
- Appears as brown, gray, or black marks
- More common in darker skin tones
- Can have irregular shapes
- Does not blanch when pressed
Treatment Approaches
The treatment for PIE and PIH differs due to their distinct underlying causes:
- PIE often responds well to treatments that target blood vessels, such as vascular lasers or intense pulsed light (IPL) therapy.
- PIH typically requires treatments that inhibit melanin production or promote cell turnover, such as hydroquinone, kojic acid, or chemical peels.
Both conditions can benefit from sun protection, as UV exposure can worsen their appearance and slow the healing process.
