Redness on the skin is a typical problem that many people face, and it can be caused by a combination of factors such as acne, eczema, or rosacea. While these conditions can be treated, they can often leave behind a persistent redness known as post-inflammatory erythema (PIE). PIE can be frustrating to deal with, particularly since it can take weeks or even months to fade on its own. However, there are steps you can take to speed up the healing process and banish redness for good.
We’ll explore what post-inflammatory erythema is, what causes it, and how to treat it effectively. From skincare tips to professional treatments, we’ll cover everything you need to know to get clear, healthy-looking skin. Whether you’re dealing with mild or severe redness, this guide is designed to help you find the best solutions for your skin type and needs. So, let’s get started and say goodbye to redness once and for all!
What Is Post-Inflammatory Erythema?

Post-inflammatory erythema (PIE) is a type of redness that occurs on the skin as a result of inflammation. It’s a common concern that affects people of all skin types, but it’s quite common in those with fair or light skin tones. PIE is distinct from other types of skin redness because it’s caused by an excess of blood flow to the affected area, rather than an underlying skin condition like rosacea.
PIE typically occurs as flat, pink, or red spots on the skin, and they can be quite noticeable and persistent. It can also be brought on by abrasive skincare products, sun exposure, or physical trauma to the skin. It frequently results from inflammatory skin conditions like acne or eczema.
While PIE isn’t a severe medical condition, it can be a cosmetic concern for many people. The good news is that there are several effective treatments available to lessen the appearance of PIE and help enhance the overall look and health of your skin. By understanding the causes and symptoms of PIE, you can take steps to treat it and prevent it from recurring in the future.
Dr. Lauren Levy explains that post-inflammatory erythema will typically fade on its own over time, with a complete resolution taking anywhere from 4 to 8 weeks. However, treatment can speed up the fading process. It’s also important to wear sunscreen, as exposure to the sun can worsen PIE, and treatment may increase your skin’s sensitivity to burning.
The Causes and Prevention of Post-Inflammatory Erythema (PIE)
Post-inflammatory erythema (PIE) is a sort of skin redness that can be caused by a variety of factors, including inflammatory skin conditions, harsh skincare products, sun exposure, and trauma to the skin. Here are some of the standard causes of PIE and how to prevent it from occurring:
- Inflammatory Skin Conditions
Inflammatory skin conditions such as acne, eczema, and psoriasis can lead to PIE, which can persist long after the initial inflammation has resolved. To prevent PIE, it is important to treat the underlying condition effectively, such as using topical or oral medications to reduce inflammation and prevent scarring.
- Harsh Skincare Products
Using harsh skincare products can also lead to PIE. Products that contain harsh ingredients like alcohol, fragrances, or exfoliants can irritate the skin and cause redness. To prevent PIE caused by harsh skincare products, it’s important to choose products that are gentle and non-irritating. Look for products labeled as “fragrance-free,” “non-comedogenic,” and “hypoallergenic,” and avoid using products that contain ingredients that are known to be irritating or drying.
- Sun Exposure
Sun exposure is another common cause of PIE. UV radiation can cause damage to the skin, leading to inflammation and redness. To prevent PIE caused by sun exposure, it’s important to protect your skin from the sun’s harmful rays by wearing sunscreen with a minimum SPF of 30 every day, even on cloudy days. You should also wear protective clothing like long-sleeved shirts, hats, and sunglasses when spending time outdoors.
- Trauma to the Skin
Trauma to the skin, such as from picking at acne or undergoing a cosmetic procedure like laser treatment, can also cause PIE. To prevent PIE caused by trauma to the skin, it’s important to avoid picking at pimples or other blemishes on the skin. It’s also important to follow all post-treatment instructions provided by your dermatologist or skincare provider to ensure proper healing and prevent complications.
Post-inflammatory erythema can be caused by a variety of factors, but there are steps you can take to prevent it from occurring. By treating underlying inflammatory skin conditions, choosing gentle skincare products, protecting your skin from the sun, and avoiding trauma to the skin, you can help keep your skin looking clear and healthy. If you are struggling with PIE, consult with a dermatologist or skincare professional to discuss the best treatment options for your skin type and concerns.
The Treatments for Post-Inflammatory Erythema (PIE)
Post-inflammatory erythema (PIE) can be a frustrating condition to deal with, but there are several useful treatments available to reduce the appearance of redness and improve the prevailing health of your skin. Here are some of the most familiar treatments for PIE:
- Topical Treatments
Topical treatments are often the first line of defense against PIE. These treatments can help reduce inflammation and redness, and they may contain ingredients like azelaic acid, niacinamide, or retinoids. Your dermatologist or skincare professional may also recommend topical steroids for more severe cases of PIE. It’s important to follow your healthcare provider’s instructions carefully when using topical treatments, as some can be irritating or dry to the skin.
- Professional Treatments
If topical treatments aren’t effective, your dermatologist or skincare professional may recommend professional treatments like laser therapy or chemical peels. Laser therapy works by targeting the blood vessels responsible for the redness in PIE, while chemical peels can help exfoliate the skin and reduce inflammation. These treatments are typically performed in-office and may require several sessions for optimal results.
- Cortisone Injections
For particularly stubborn cases of PIE, cortisone injections may be recommended. Cortisone is a powerful anti-inflammatory medication that can help reduce redness and swelling quickly. These injections are typically performed by a dermatologist and can provide rapid relief for PIE.
- Camouflage Makeup
While not a treatment per se, camouflage makeup can be an effective way to hide the appearance of redness caused by PIE. Many brands offer special formulas designed to conceal redness and provide a natural-looking finish. These products can be a good option for those who want to temporarily conceal redness while undergoing other treatments for PIE.
