How to Get Rid of Post-inflammatory Erythema.

Scars left by acne pimples or other skin eruptions come in a variety of forms. How to remove or reduce them depends on the type of scar. In the case of post-inflammatory erythema treatment, the beauty routine should include the use of suitable skincare products containing moisturizing ingredients (aloe vera, glycerine, hyaluronic acid, polyglutamic acid…). However, if scars are too pronounced, laser treatment can provide effective results.

What Are Erythematous Scars?

Following skin trauma, the skin heals. This natural, life-saving process can give rise to various types of skin marks: brown or pigmented scars, blistered or keloid scars, pitted or cratered scars, whitish ball scars or perifollicular elastolysis, or red or erythematous scars, which are the ones we're interested in here.

Red scars are also known as erythematous scars or post-inflammatory erythema. Unlike other types of scarring, these manifestations persist for several months, but usually disappear eventually. These marks are caused by vasodilatation of superficial cutaneous vessels, and are more visible on fair skins.

They can be caused by acne pimples, insect bites or various skin traumas. Erythematous scarscan cause discomfort, pain, or feelings of discomfort.

How to Remove Erythematous Scars?

Although most scars are difficult, if not impossible, to remove completely without recourse to cosmetic surgery, erythematous marks can nevertheless be greatly reduced or even erased. What's needed is prompt attention and an appropriate beauty routine. The post-inflammatory erythema treatments to be applied do vary according to the healing phase.

During the inflammatory phase, between 1 and 3 days, the use of an anti-infection skin care product is recommended. For example, several studies have reported the anti-inflammatory properties of vitamin C. It acts by inhibiting NFkB, a transcription factor involved in the immune response and responsible for activating a number of pro-inflammatory cytokines such as TNF-alpha, IL1, IL6 and IL8. In this way, vitamin C prevents redness and post-inflammatory erythema. 

Then, during the repair phase, between 3 and 15 days, the application of a suitable skincare product helps to close the wound. Certain ingredients, such as Centella asiatica, may be useful. Through the action of the saponosides and triterpenes this plant extract contains, it promotes collagen production. In addition to preventing skin aging, this protein ensures cell regeneration and thus tissue repair.

You can also intervene during the remodeling phase, up to 2 years after scar formation. To reduce the appearance of post-inflammatory erythema, we recommend a skincare product containing a moisturizing active ingredient, such as hyaluronic acid or polyglutamic acid, to soften and smooth their appearance. These two ultra-moisturizing active ingredients help rebuild damaged skin tissue.

Acid-based cosmetics (AHA, BHA and PHA) in low concentrations (up to 20%) can also be used to reduce the appearance of erythematous scars. However, several applications at regular intervals will be necessary to achieve visible results. You can use an exfoliating serum containing 10% glycolic acid, or a gentle peeling serum based on lactic acid, more suitable for sensitive skin. The anti-marks serum targets acne scars specifically and is applied locally. It contains PHA, gluconolactone and Centella asiatica extract, an active ingredient renowned for helping to remodel the relief of marked skin.
