The Astria Acne Scar Recovery Protocol is a doctor-designed, dual-modality treatment programme that combines Yellow Laser with PN Scar Booster to target two important pillars of acne scar recovery – inflammation reduction, by creating an optimal healing environment through the reduction of persistent inflammation and post-acne redness, and collagen stimulation, by promoting structural skin repair through collagen regeneration within depressed acne scars.
Rather than viewing acne scars as merely indentations, this protocol recognises that successful scar improvement depends on restoring the skin’s ability to repair itself. By addressing both the surface healing environment and the deeper dermal structure, the protocol aims to produce more comprehensive and natural-looking improvements.
Yellow Laser uses a 585nm wavelength of light that is selectively absorbed by oxyhaemoglobin (the pigment found in blood vessels). This enables it to target and reduce overactive blood vessels while minimising damage to the surrounding skin. By reducing persistent post-acne redness, also known as post-inflammatory erythema (PIE), and calming inflammation, Yellow Laser helps create a healthier skin environment that supports collagen repair and the skin’s natural healing process.
PN Scar Booster works by delivering polynucleotides (PN) into targeted scar areas to support the skin’s natural repair mechanisms. Rather than temporarily filling a scar, it focuses on improving the quality of scar tissue by encouraging biological regeneration. This helps address depressed acne scars, which develop when inflammation damages the skin’s collagen framework during the acne healing process.
Post-Inflammatory Erythema (PIE) are the red or pink marks that lingers for months even after the breakout has resolved, making the skin appear inflamed despite the absence of active acne.
The Acne Scar Recovery Protocol uses Yellow Laser to selectively target these abnormal blood vessels, helping to reduce redness and calm residual inflammation. This creates a clearer, more even complexion while preparing the skin for the regenerative effects of PN Scar Booster.
Depressed acne scars develop when inflammation damages collagen in the deeper layers of the skin, leaving permanent indentation. The Acne Scar Recovery Protocol combines the anti-
inflammatory effects of Yellow Laser with the regenerative properties of PN Scar Booster. While Yellow Laser helps optimise the skin’s healing environment, PN Scar Booster supports collagen regeneration within the scar, allowing gradual improvement in scar depth and overall skin texture.
Acne can leave behind skin that feels rough or uneven due to a combination of scar tissue, collagen loss and prolonged inflammation. Even if individual scars improve, overall skin texture may still appear irregular. The Acne Scar Recovery Protocol addresses these concerns by combining Yellow Laser to improve skin clarity and reduce residual redness with PN Scar Booster to strengthen the structure. Together, they promote healthier skin remodelling and progressively smoother skin texture.
Even after acne has resolved, the skin may remain fragile, sensitive and slower to repair because of previous inflammation and collagen damage. The Acne Scar Recovery Protocol creates a more favourable healing environment by reducing residual inflammation with Yellow Laser, while PN Scar Booster supports tissue regeneration and collagen synthesis. This dual approach helps restore healthier, stronger skin as part of the scar recovery process.
| Scar Type | Rolling Scars | Boxcar Scars | Ice Pick Scars |

| How It Looks |  | | |
| How The Protocol Helps | Yellow Laser helps reduce persistent inflammation and creates a healthier environment for skin repair, while PN Scar Booster stimulates fibroblast activity and collagen remodelling. Subcision can also be done to release underlying fibrous bands. | Yellow Laser improves the skin’s healing environment by reducing residual inflammation, while PN Scar Booster promotes collagen regeneration within the scar tissue. Together, they gradually soften scar edges, improve dermal support and enhance overall skin smoothness. | PN Scar Booster may help improve the quality of the surrounding skin and support collagen regeneration, while Yellow Laser reduces residual redness around healed acne lesions. |
Treats persistent post-acne redness while supporting collagen regeneration within depressed scars, providing a comprehensive recovery.
Stimulates the skin’s own repair mechanisms, encouraging gradual collagen remodelling which allows for natural looking results.
Treatment settings and injection techniques can be tailored according to the scar type, distribution and severity.
May be incorporated into a acne scar management programme alongside treatments such as Morpheus8 or Fractional CO2 Laser.
Acne scars are formed through complex processes. While Yellow Laser and PN Scar Booster are both effective treatments, they work on completely different aspects of acne scar recovery. When used together, they create a more comprehensive recovery strategy by preparing the skin for regeneration before stimulating collagen remodelling within the scar.
| Concerns | Yellow Laser | PN Scar Booster | Astria Acne Scar Recovery Protocol |
|---|---|---|---|
| Red Acne Marks (PIE) | Effective. Seals tiny blood vessels to clear post-acne red marks. | Minimal. Skin boosters do not shrink or target blood vessels. | Rapidly shuts down redness while accelerating deep skin healing. |
| Sunken & Pitted Scars | Minimal. Does not add volume or rebuild sunken scar tissue. | Effective. Supports dermal regeneration and collagen remodelling, allowing scars to gradually become shallower over time. | Temporary slight lift in scars combined with long-term collagen growth. |
| Skin Inflammation | Effective. Reduces inflammation from acne flares. | Effective. PN calms and rebuilds the damaged skin. | Synergistic effect to reduce inflammation of acne. |
| Overall Result | Clears red marks but leaves indentations and pitted scars untreated. | Lifts scars but leaves underlying red marks and flushing visible. | Simultaneously clears redness and lifts depressed scars for smooth, even-toned skin. |
The Astria Acne Scar Recovery Protocol is designed as a progressive skin recovery programme. While Yellow Laser can produce relatively early improvements in post-acne redness, PN Scar Booster works by stimulating your body’s natural collagen regeneration process, which takes time. For this reason, improvements typically occur in stages, with skin continuing to remodel for several months after each treatment.
To achieve the best outcome, the protocol is typically performed at 3 to 4-week intervals. This allows the skin sufficient time to heal and begin collagen remodelling before the next treatment. Most patients require 3-5 sessions initially before going onto maintenance, depending on the severity, type and extent of acne scarring. This will be best advised by your doctor as your treatment progresses.
One of the advantages of The Astria Acne Scar Recovery Protocol is that it offers minimal downtime while addressing both post-acne redness and depressed acne scars. As the protocol combines Yellow Laser with PN Scar Booster, recovery is generally well tolerated, and most patients can return to their normal daily activities shortly after treatment. The table below shows the typical downtime for the treatments.
During your initial consultation, we can modify and integrate targeted clinical treatments to treat your specific aesthetic concerns. Below are some concerns and customizations that we can make:
| Treatment | Common Post-Treatment Reactions | Typical Downtime |
|---|---|---|
| Yellow Laser | Mild redness, warmth or slight swelling like a mild sunburn. | Usually a few hours to 1 day. |
| PN Scar Booster | Small injection bumps, mild swelling, pinpoint bruising or tenderness at injection sites. | Approximately 2-3 days (occasionally up to 5 days depending on the treatment area). |
| Combined Astria Acne Scar Recovery Protocol | Temporary redness with small injection bumps that gradually resolve over a few days. | Most patients recover within 1-3 days, although minor bruising may last slightly longer in some individuals. |
To ensure the best results and recovery, avoid heavy exercise, alcohol and saunas for the first 24 hours. Use gentle cleansers and a fragrance-free moisturizer for the first 2–3 days and apply a broad-spectrum SPF daily to protect your treated skin. Staying well-hydrated will also help support the skin’s recovery process.
Our team will go through a registration process with you to collect basic details and understand your skin concerns.
Your skin is thoroughly cleansed to remove makeup, oil, and impurities to prepare the skin for treatment.
Photos are taken to document your current skin condition and referenced during the doctor’s consultation.
A topical numbing cream is applied to minimise discomfort during the procedure.
Our doctor will discuss your concerns, goals, and medical history to ensure the treatment is tailored to your needs.
Your Yellow Laser treatment is tailored with customised settings to address your unique skin concerns.
PN Scar Booster is administered via manual injection to target your areas of concern.
A calming sheet mask is applied to soothe the skin. Our team will advise you on what to do and expect in the next few days.
Yes, it is safe for both dry and oily skin types. Yellow Laser specifically targets oxyhaemoglobin inside blood vessels, hence minimising unnecessary heat damage to the skin. Combined with the anti-inflammatory properties of PN, the protocol minimizes heat stress and significantly reduces the risk of PIH.
Discomfort is minimal. Prior to treatment, a medical-grade numbing cream is applied for 30 minutes. The Yellow Laser feels like mild, warm flashes with slight tingling. The PN SKin Booster is delivered using a very fine needle; most patients report only mild, brief pin-prick sensation at individual scar sites.
You may notice some subtle improvement in skin redness and overall skin quality after a single session. However, collagen regeneration is a gradual process. Stopping after one session may limit the overall improvement in depressed acne scars, as most patients achieve better results after completing the recommended treatment programme.
Yes. Depending on your scar type, your doctor may recommend combining this protocol with treatments such as Morpheus8 RF Microneedling or Fractional CO2 Laser for more complex acne scars.
Your treatment plan will be customized according to the type, depth and severity of your scars rather than using the same approach for every patient. The best approach would be to schedule a consultation with our doctors so that we can assess suitability of the treatments.
No. PN Scar Booster is not designed to fill acne scars with immediate volume. Instead, it delivers PN that support your skin repair cells and collagen regeneration, allowing the skin to gradually repair and lift the scar over time. Improvements develop progressively as your own collagen remodels.
Acne can leave many patients with persistent redness and depressed scars caused by collagen loss. Treating only one of these concerns often leaves patients disappointed, as the skin may still appear scarred or inflamed even when the acne itself has cleared.
The Astria Acne Scar Recovery Protocol combines Yellow Laser and PN Skin Booster (Scar) in a carefully sequenced treatment programme to address both the vascular changes that make scars appear more noticeable and the structural collagen loss responsible for depressed scars. Instead of simply resurfacing the skin, this protocol focuses on creating an environment where scarred skin can progressively heal itself for smoother, healthier-looking skin over time.
