Post-inflammatory erythema (PIE) is a common skin concern characterized by pink to red marks left behind after acne or other inflammatory skin conditions. While PIE is temporary, it can be very stubborn and take a long time to fade. In this blog, we will cover the causes of PIE, how it differs from post-inflammatory hyperpigmentation (PIH), and explore the most effective treatments to fade these marks.
What is Post-Inflammatory Erythema?
Post-inflammatory erythema (PIE) are red marks that result from inflammation triggered by acne, dermatitis, or other skin traumas. These marks are caused by dilated blood vessels near the skin's surface, making them appear more pronounced.
What Causes Post-Inflammatory Erythema?
Acne: Acne is the most common cause of post-inflammatory erythema. The redness that is left behind after a pimple is due to increase blood vessels and pigment.
Picking the Skin: Squeezing or picking at blemishes prolongs the healing process and increases the likelihood of PIE.
Bacteria: Bacterial overgrowth in the pores can exacerbate inflammation.
Harsh Products: Aggressive skincare products can disrupt the skin's barrier, leading to inflammation.
Hormonal Fluctuations: Hormonal imbalances can trigger acne and subsequent PIE.
Excess Dead Skin: Accumulation of dead skin cells can block pores, leading to inflammation.
