What is Post-Inflammatory Erythema (PIE)?

Post-Inflammatory Erythema (PIE) or red acne scar is the reddish mark left behind on the skin that appear due to capillaries at the skin surface being damaged by acne inflammation and popping pimple activity by human. Those who have lighter skin tones will be more susceptible to get PIE while in majority cases, darker skin tones will get higher chance to be affected by Post Inflammatory Hyperpigmentation (PIH). Read our ENTRY HERE to read more on Post-Inflammatory Hyperpigmentation, also known as dark acne scars which are melanin-caused mark left on the skin. 

To detect PIE, simply press the redness area, the redness should go away and will look white (check now for confirmation!)

Prevention is Better than Cure

If you’re currently do not experience PIE, it is best for you to take note on these tips below so that you can always always avoid getting PIE on your face! It takes only a few days for acne to soothe but PIE can take a long period of time to heal, just like PIH. However, this depends on your personal skin healing response and other environmental condition may affect too.

DOsDON’Ts
Follow skincare routine that prevents acne formation. Read our ENTRY HERE for more info.Don’t pick your pimples or acne as this will lead to inflammation and increase PIE chance to appear on your skin.

Search for anti-inflammatory, skin barrier repair, collagen booster (like retinoid and Vitamin C!) and humectants in your skincare product to aid in skin’s natural recovery process. 

Try our Repairing and Soothing Facial Serum (RSS). It contains all of those needed ingredients for your skin to recover itself! Niacinamide, Centella Asiatica and Hyaluronic Acid, to name a few…

Do not use physical scrub, treatment, peels, facial brush as they will make your skin more prone to getting irritation and eventually causes broken capillaries. 
Wear sunscreen in your AM routine! Reapply every 2 to 3 hours. When exposed to the sun, the sun will slow down the skin barrier repair process and may lead to further skin damage to the inflamed skin. Don’t delay on seeking for help and treatment from dermatologists for early sign of acne and blemishes if possible.
Make sure you are changing your pillowcase and cleaning your phone devices once a week. Avoid touching your face if you are prone to acne and breakout. Reducing acne will reduce chance of getting PIE!

Unlike PIH which can be treated with skin lightening agent or brightening ingredients that address melanin, PIE is far more difficult to treat in real life. These ingredients will have limited effects on the redness as they work more on melanin-caused mark by inhibiting melanin production or preventing melanosome transfer rather than vasculat-related redness.

Some anti-inflammatory ingredients will really help to reduce redness for rapid skin healing process. Some notable ingredients include Niacinamide, Witch Hazel, Allantoin, Green Tea, Centella Asiatica extract and Panthenol. Collagen booster like ANTIOXIDANT (read HERE for more info) and retinoid help in stimulating more collagen to repair the skin barrier. Niacinamide, the famous skin barrier repairing ingredient aids in stimulating ceramide for enhanced skin barrier look. 

However, according to dermatologists, in-clinic lasers have been proven to show more effective ways for PIE treatment. They offer a speedy recovery even further but at the same time, supporting a good skincare routine. *Darker skin tones really need to consult dermatologist to avoid PIH comes after PIE treatment

Some clinical approaches to treat stubborn PIE includes laser treatment such as Vascular Laser. 

 

TreatmentsExplanationReferences
Vascular Lasers

Heat-based treatments that specifically target intravascular oxyhaemoglobin in dermal blood vessels.

Oxyhaemoglobin absorbs the laser light which is then converted to heat and transferred to blood vessel wall, eventually causing closure of blood vessel.

Z Hussains, 2016
Pulsed Dye laser (PDL) therapy

Selectively targets oxyhaemoglobin in blood vessel, removing damaged capillaries located near to the skin surface which causes the red acne scars to appear.

Longer wavelengths and extended pulse durations have enabled deeper tissue penetration for better outcome.

N/A
Potassium Titanyl Phosphate

Targets melanin, oxyhaemoglobin and red tattoo pigment. This treatment uses shorter wavelengths, causing decreased tissue penetration and limited absorption by haemoglobin in deeper vessels.

*more suitable for fair skin

Intensed Pulsed Light Therapy (IPL)78% patients reported better PIE improvement.ML. Mathew et al, 2018
