What is Post Inflammatory Erythema (PIE)?
Red acne marks / scars otherwise known as post inflammatory erythema (PIE) can be stubborn and often a source of frustration. Even with no treatment, PIE marks eventually fade. However, the process is slow and can take several months to a year.
What causes PIE?
PIE develops due to damage and dilation of small blood vessels (capillaries) near the surface of the skin.
It is commonly caused by
- Inflamed acne
- Incorrectly “popping” or picking of pimples
- Trauma to the skin such as scraps or scratches
- Chemical / laser burns
Simple test for PIE
Apply pressure to the red marks and if they temporarily disappear, it is most likely PIE.
How can we treat PIE?
Vascular lasers like the Pro-yellow laser or Spectra XT “Gold-Toning” 595nm lasercan effectively treat PIE by targeting hemoglobin through the process of selective photothermolysis.
The lasers safely penetrate skin to break down and disperse damaged blood vessels, thereby reducing the appearance of PIE.
Aside from lasers, look for these ingredients in your skincare products as they have been described to improved PIE.
- Vitamin A
- Green tea extracts
- Vitamin C and Vitamin E
Our Anti-Blemish Serum and Ultra Light Hydrator were specially formulated with these ingredients to reduce the appearance of blemishes and improve acne.
