What Is Post-Inflammatory Erythema (PIE)?
Post-Inflammatory Erythema (PIE) is a skin condition characterised by pink or red marks that appear after inflammation, often following acne. It is more prevalent in individuals with lighter skin tones (Fitzpatrick skin types I-III) and can persist for months or even years if not treated. The lasting appearance of PIE can impact self-esteem and confidence, highlighting the importance of timely treatment for both skin health and emotional well-being.

Causes of Post-Inflammatory Erythema (PIE)

Unlike scars or pigmentation changes, PIE results from damage to small blood vessels beneath the skin’s surface, causing visible redness. Some common causes include:
- Acne Vulgaris: Inflammatory acne lesions, like pustules or cysts, are a major cause of PIE.
- Skin Injuries: Scratches, cuts, or wounds that cause inflammation can lead to PIE.
- Other Inflammatory Skin Conditions: Conditions like eczema, rosacea, and dermatitis can trigger erythema.
- Treatments: Procedures such as microdermabrasion or laser treatments can cause PIE if the skin isn’t properly protected during healing.
Symptoms of Post-Inflammatory Erythema (PIE)



PIE presents as flat red, pink, or sometimes purple spots in areas previously affected by acne or inflammation. These spots may be sensitive, worsen with heat or sun exposure, and can persist for months without treatment. While PIE doesn’t cause bumps or scarring, its persistence can lead to psychological distress.
Post-Inflammatory Erythema (PIE) vs. Post-Inflammatory Hyperpigmentation (PIH)
Both PIE and Post-Inflammatory Hyperpigmentation (PIH) result from inflammation but differ in cause and appearance. PIE presents as red or pink spots from capillary damage, common in lighter skin tones. PIH appears as brown or dark spots due to excess melanin, more common in darker skin tones (Fitzpatrick types IV-VI). PIE results from vascular damage, while PIH is pigmentation-related, and both can coexist, particularly in acne cases.
How to Prevent Post-Inflammatory Erythema (PIE)?

Preventing PIE largely involves controlling the initial inflammation and avoiding further irritation to the skin. Key prevention strategies include:
- Avoid Picking or Squeezing: Picking at acne lesions or scratching inflamed skin can worsen PIE by further damaging the capillaries.
- Gentle Skincare: Use mild, non-irritating cleansers and moisturisers to support the skin’s healing process.
- Treat Acne and Inflammatory Conditions Early: Prompt treatment of acne or other skin conditions such as eczema can reduce the chances of developing PIE.
- Sun Protection: Daily use of a broad-spectrum sunscreen (SPF 30 or higher) helps protect the skin and prevent worsening erythema.
How to Prevent Post-inflammatory Erythema (PIE)?
PIE may fade naturally over time, but for those seeking faster resolution, several treatment options can effectively reduce redness and speed up recovery:
Treatment Options | Description |
---|---|
Topical Treatments | Moisturisers and steroids are used to manage inflammation and soothe the skin, aiding in the improvement of PIE. Moisturisers help restore the skin barrier and maintain hydration, while steroids reduce redness and inflammation, promoting faster recovery. |
Light and Laser Treatment | For advanced PIE, light treatments such as Intense Pulsed Light (IPL) can be effective in reducing symptoms. For deeper, more persistent cases, the Q-switch laser is effective for treating vascular lesions. |
Sun Protection | While sunscreen does not directly treat PIE, it is crucial in preventing it from worsening. UV exposure can dilate blood vessels and make redness more pronounced, so daily sunscreen use is essential for those with PIE. |
