Red Acne Scars

Post-inflammatory erythema (PIE), also known as macular erythema, refers to flat, red scars that result from inflammation caused by various conditions, including acne, chickenpox, and trauma from peels and lasers.

Unlike PIH, which is a form of hyperpigmentation that predominantly affects darker skin types, PIE can occur in both light and dark-skinned individuals. The natural course of PIE involves gradual improvement over a period of 2-12 months. However, in some cases, it may take years or longer for the scars to fade.

The most effective way to manage PIE is to apply sunscreen regularly, especially in the early stages, as this can significantly reduce the likelihood of developing PIE.

For established red scars, a vascular laser is often used. This type of laser targets the haemoglobin in the blood vessels, heating them up and causing the small capillaries to collapse, thereby improving PIE. In cases where both red and brown scars are present, a picosecond laser may be used in combination.

The number of sessions required to treat PIE depends on the duration of the scars, your skin type, and your response to laser therapy. Typically, patients require between 2-4 sessions spaced 2-4 weeks apart. However, if you have darker skin or resistant scars, you may require four or more treatments.

A consultation with a specialist laser dermatologist is necessary.

At Skin Specialist Centre, we offer several vascular laser options to treat PIE or red marks. Click below to learn more about the laser:

1. Excel V+
2. VBEAM Perfecta
3. Laser Genesis
4. Prodeep - Etherea MX

All of these devices are effective in treating PIE, and the appropriate device for you will depend on the specific characteristics of your red scars and skin type.

In addition to laser therapy, our dermatologists and nurses offer several other scar revision techniques, including:

1. Deep focal peels: Using TCA in a technique known as CROSS.
2. Laser resurfacing: Full ablation using CO2 lasers.
3. Fractional lasers: Acclaro UltraClear and Alma Hybrid
4. Subcision: Using techniques such as , blunt cannula and hypodermic.
5. Surgical: Punch elevation, excision.
6. Dermal filler +/- sculptra (biostimulators)

These techniques can be tailored to your specific needs and may be used in combination with laser therapy for optimal results.

Laser treatments for PIE are typically not painful. The lasers we use come equipped with a cooling system to minimise discomfort and potential side effects. If needed, a topical anaesthetic cream is offered. The treatments usually takes around 5-10 minutes to complete.

Topical anti-inflammatory creams prescribed by dermatologists can be effective in treating PIE. However, over-the-counter creams may not be as effective.

It is important to note that consistent use of sunscreen is crucial in managing PIE and can make a significant difference in improving the appearance of red scars.

Sunscreen is crucial in managing redness or PIE since exposure to UV rays can exacerbate the condition. To protect your skin, it is recommended to use a SPF50 Sunblock.

To use sunscreen effectively, apply 2-3 ml to your face and neck in the morning. For optimal protection, reapply the same amount of sunscreen at noon.

Before undergoing PIE treatments, it is important to keep in mind the following points:

1. Control your acne to achieve the best results with any scar revision treatment. Seek the help of a cosmetic laser dermatologist if necessary to achieve optimal control.
2. Sun protection is paramount. Use SPF 50+ sunscreen twice a day regardless of exposure.
3. More than one treatment is typically necessary to achieve optimal results. Patients with severe PIE may require 3-4 sessions, while those with deep red scars may need up to six or more sessions.
4. Darker skin types may require more sessions compared to lighter skin.
5. The settings of the laser used for treatment are crucial for achieving the best outcomes. The correct choice of laser brand is also vital for good results.

By keeping these points in mind, patients can achieve the best possible outcomes and maximise the benefits of their investment in scar revision treatment.
