How to Treat Post-Inflammatory Erythema (PIE)?

[Andrew Sherman]

IPL emits a broad spectrum of light that penetrates the skin's surface, targeting the dilated blood vessels responsible for the redness in PIE. By gently heating and constricting these vessels, IPL significantly reduces inflammation. The targeted energy from the IPL laser is absorbed by the red blood cells in the affected area. This absorption converts to heat, causing the blood vessels to collapse and diminish in appearance, thereby reducing redness. PIE can cause uneven pigmentation, giving the skin an overall blotchy appearance. IPL treatments effectively break down excess melanin, evening out the skin tone and leaving it looking more uniform.

Vitamin C is a powerful ally in reducing both red and brown scars. Its potent inhibitory effect on tyrosinase can minimize dark pigmentation, while its antioxidant and collagen-stimulating properties aid in fading PIE. Azelaic Acid, Retinoids, Arbutin, Tranexamic Acid, and Niacinamide are other skincare ingredients that can be effective in pie acne treatment. For best results, we recommend pairing in-clinic treatments with at-home skincare.

PIE is typically quite stubborn to fade when left untreated. In some individuals, PIE can persist for upwards of a year. Targeted in-clinic treatments can expedite the process. PIE is dependent on inflammation, making it more likely to occur with inflammatory acne types. Fair-skinned individuals and those with thinner skin are more susceptible due to the increased visibility of blood vessels during the skin repair process.

Microneedling can be an effective treatment for PIE, as it stimulates collagen production and promotes faster healing. However, IPL or vascular lasers are going to be a more targeted, effective treatment for post-inflammatory redness.
