NeoGen PSR for Acne Scars Calgary: Results & Timeline

Quick answer: NeoGen PSR uses nitrogen plasma energy to resurface skin and stimulate collagen production, reducing the appearance of acne scars over a series of treatments. Most patients need 3 to 5 sessions spaced 6 to 8 weeks apart, with visible improvement building over 3 to 6 months as new collagen remodels the scar tissue.

Acne scars are one of the most persistent skin concerns in aesthetic medicine. Unlike active breakouts, which resolve with time or treatment, scars represent structural changes in the skin — damaged collagen architecture that doesn’t heal back to its original form on its own.

NeoGen PSR (Plasma Skin Regeneration) is one of the most effective non-surgical tools available for treating acne scars. By delivering controlled nitrogen plasma energy to the skin surface, it triggers a precise wound-healing response that rebuilds collagen and resurfaces the skin from the inside out. At Arlo Medical in Calgary, we use NeoGen PSR as a primary treatment for moderate to severe acne scarring.

What Are Acne Scars?

Acne scars form when inflammatory acne damages the dermis — the deeper layer of skin where collagen fibers provide structure and support. As the skin heals, it produces collagen in a disorganized pattern, resulting in textural irregularities that persist long after the acne itself has resolved.

There are several types of acne scars, each with different structural characteristics:

Ice pick scars: Narrow, deep pits extending into the dermis
Boxcar scars: Wider, flat-bottomed depressions with defined edges
Rolling scars: Broad, shallow depressions with sloping edges that give a wave-like appearance
Hypertrophic scars: Raised scars formed from excess collagen (less common with acne)

NeoGen PSR is most effective for rolling and boxcar scars, as well as overall skin texture irregularities from acne. Ice pick scars may benefit from combined approaches.

How NeoGen PSR Treats Acne Scars

NeoGen PSR delivers controlled pulses of nitrogen plasma energy to the skin. Unlike lasers that use light wavelengths, nitrogen plasma creates a thermal effect across the full skin surface — both the outer epidermis and the underlying dermis benefit from the treatment simultaneously.

This triggers a controlled wound-healing cascade. The body responds by breaking down damaged collagen and producing new, organized collagen in its place. The epidermis regenerates with improved texture and tone, while the deeper remodeling process fills and smooths the scar depressions from below (Bogle et al., 2007).

The result is progressive improvement in scar depth, texture, and skin surface quality over several months following each treatment.

What Results Look Like — and When

NeoGen PSR results for acne scars develop gradually. Unlike injectable treatments where you see an immediate change, plasma resurfacing works through a biological remodeling process that takes time.

A typical treatment timeline looks like this:

Days 1–7: Healing phase

Immediately after treatment, the skin develops a bronzed appearance and carbon crusting that resembles moderate sunburn. This is the normal epidermal response and signals that the resurfacing process has begun. The crust protects the regenerating skin beneath and falls away naturally within 5 to 7 days. During this phase the skin needs to be kept clean, moisturized, and protected from sun exposure.

Weeks 2–6: Early regeneration

Once the crust resolves, the new epidermis is visible. The skin often appears smoother and more even-toned than before, though some redness may persist for 2 to 4 weeks. Scar improvement is beginning but the deeper collagen remodeling is still underway.

Months 2–6: Collagen remodeling

This is when the most significant improvement becomes visible. New collagen fills in scar depressions, and the overall surface texture continues to refine. Most patients see their best results 3 to 6 months after each treatment session.

Cumulative improvement across sessions

Each treatment builds on the last. Most patients with moderate to severe acne scarring require 3 to 5 sessions spaced 6 to 8 weeks apart. Results accumulate with each session, and patients typically see 40 to 60% improvement in scar appearance over a full treatment course (Elsaie et al., 2011).

Who Is a Good Candidate?

NeoGen PSR for acne scars works best for adults with:

Moderate to severe acne scarring (rolling, boxcar, or mixed types)
Overall skin texture irregularities from past breakouts
Active acne that is currently under control (not actively inflamed)
Fitzpatrick skin types I–IV (lighter to medium skin tones respond best)
Realistic expectations about gradual, progressive improvement

NeoGen PSR is not recommended for those with active acne breakouts in the treatment area, recent use of isotretinoin (Accutane) within the past 6 to 12 months, darker skin types (Fitzpatrick V–VI) due to risk of post-inflammatory hyperpigmentation, or during pregnancy or breastfeeding. A consultation will confirm whether NeoGen PSR is the right approach for your skin type and scar pattern.

What to Expect at Your Appointment

A NeoGen PSR session at Arlo Medical typically takes 30 to 60 minutes depending on the size of the treatment area.

Preparation. A topical numbing cream is applied 30 to 45 minutes before treatment to manage discomfort.

Treatment. The practitioner passes the NeoGen PSR handpiece systematically across the treatment area. You will feel a warm, stinging sensation with each pulse. The number of passes and energy level are calibrated to your skin type and the depth of your scars.

Immediately after. The skin will appear bronzed to red and feel warm, similar to a moderate sunburn. The bronzed appearance darkens slightly over the next 24 hours as the superficial crust forms.

Duration. Most patients need 3 to 5 sessions spaced 6 to 8 weeks apart for optimal acne scar improvement. Your injector will recommend a treatment plan based on your scar type and severity.

Aftercare

Proper aftercare is essential for both safety and results:

Keep the treated area clean and moisturized — use a gentle, fragrance-free moisturizer
Do not pick, scratch, or forcibly remove the crust — let it fall away naturally
Apply SPF 30+ daily from the moment healing begins and for at least 30 days after
Avoid direct sun exposure on the treated area for a minimum of 4 weeks
Avoid intense exercise, saunas, and excessive sweating for the first week
Do not use retinoids, exfoliating acids, or active skincare for 2 weeks after treatment

NeoGen PSR vs. Other Acne Scar Treatments

Several treatments are used for acne scars, and the best option depends on scar type, skin tone, and how much downtime you can accommodate.

Compared to ablative CO2 laser, NeoGen PSR treats the full surface of the skin (not just targeted columns) which can produce more even results on diffuse acne scarring with comparable downtime. It also tends to be better tolerated by slightly darker skin tones than high-energy ablative lasers, though it is not appropriate for very dark skin.

For deeper, isolated scars, Plexr Plus is sometimes used as a complementary treatment — targeting individual scars directly while NeoGen PSR addresses overall skin texture.

The right approach depends on your specific scar pattern. During your consultation, your practitioner will assess which treatment, or combination, is most likely to produce the best outcome for your skin.

How Much Does NeoGen PSR Cost in Calgary?

NeoGen PSR pricing at Arlo Medical depends on the size of the treatment area and the number of sessions in your plan. Because acne scar treatment is customized to each patient’s scar pattern and skin type, the best way to get an accurate estimate is through a consultation.

Frequently Asked Questions

How many NeoGen PSR sessions do I need for acne scars?

Most patients with moderate to severe acne scarring need 3 to 5 sessions spaced 6 to 8 weeks apart. Milder scarring or surface texture concerns may respond well in fewer sessions. Your practitioner will recommend a specific plan based on your scar type and severity after assessing your skin.

Is NeoGen PSR painful?

A topical numbing cream is applied before treatment, which makes the procedure comfortable for most patients. You will feel warmth and a stinging sensation during the plasma pulses. Most patients find it manageable, though sensitive areas may feel more intense.

How long is the downtime after NeoGen PSR?

Expect 5 to 7 days of visible healing — bronzed skin and crusting that resolves naturally. Most patients return to normal activities within a week, though redness may persist for 2 to 4 weeks. Sun exposure should be avoided for at least 4 weeks after treatment.

Can NeoGen PSR be used on darker skin tones?

NeoGen PSR is most suited to Fitzpatrick skin types I–IV. Those with darker skin tones (Fitzpatrick V–VI) face a higher risk of post-inflammatory hyperpigmentation and are generally not good candidates for this treatment. A consultation will assess your skin type and recommend the most appropriate approach.

Can I combine NeoGen PSR with other acne scar treatments?

Yes. NeoGen PSR is sometimes combined with Plexr Plus for patients with a mix of diffuse texture irregularities and deeper isolated scars. Your practitioner will advise on whether a combined approach makes sense for your specific scar pattern.
