- What is Post Inflammatory Erythema (PIE)
Post Inflammatory Erythema (PIE) are the red, pink, or purple marks from inflammation (usually acne). This is a very common concern and something we see a lot of. If you are suffering from acne, please please get the correct advice to help your skin heal; some people will form PIE after acne whilst others will pick their skin and use the wrong products leading to pitted acne scars, which will take a lot of time and money to repair. If you have acne, get on the right track NOW.
You may notice these spots are red not brown. That is one of the main ways you can tell the difference between PIE & PIH This redness is a result of discrete erythematous macules or damage/dilation done to the capillaries (tiny blood vessels) close to the skin resulting in little red spots often mistaken as acne,
PIE is more common in lighter skin tones and is less likely to affect people with a slightly darker skin tone. Some people will have a mix of both PIH and PIE. PIE can sometimes turn into PIH if left untreated.
Treatments that treat PIH aim to inhibit melanin production, which unfortunately does nothing for PIE because it is not a melanin-induced problem.
What causes PIE:
PIE is inflammation caused by trauma. This may be inflamed acne, picking at spots, popping spots, dry or dehydrated skin, chemical burns, over-exfoliation, cuts, scrapes, scratches, sunburn, sun exposure and some other types of trauma.
How to test for Post Inflammatory Erythema (PIE).
Post-inflammatory erythema disappears temporarily when pressure is applied to the area. PIH does not. This is known as “skin blanching”.
To do this test on yourself, find a transparent container such as a cup or glass, and press the item down against the area you might suspect is PIE. If the mark becomes white and disappears, then that’s a good indication you have PIE and not PIH.
Hyperpigmentation (brown spots) is unaffected by this test. However, this method isn’t always the most accurate and should be used more as a guide.
The science behind treating Post Inflammatory Erythema (PIE):
There are only two main methods for treating PIE (as far as the research is concerned): vascular lasers and specific skincare products.
As mentioned above, PIE is the result of damaged or enlarged capillaries near the surface of the skin. That’s what can make vascular lasers such an effective treatment. They work by penetrating the skin deep enough to reach, break down, and disperse the damaged blood vessels, causing PIE.
Specific skincare products increase the hydration of the stratum corneum (outermost layer of skin), protect from bacterial invasion, and maintain skin barrier integrity.
They induce a moist wound healing environment to speed up the PIE-fading process.
It is said that post-inflammatory erythema (PIE) is worsened by a damaged moisture barrier or acid mantle, so focusing on the moisturising aspect of your routine and reducing irritation whenever possible is essential!
The key takeaway is to hydrate, hydrate, and hydrate some more!
Many people will call PIE acne scars when they are more of an acne stain!
