Acne scars are not all the same — some are deep and narrow, others are rolling or tethered beneath the skin. Because of this, no single treatment works for everyone.
Patients often face a key decision: should they choose a Single-Modality vs Combination Acne Scar Treatment plan? Each approach has its own role, advantages, and trade-offs.
This article explains what they involve, their pros and cons, and how doctors decide the best way forward for smoother, clearer skin.
What Is Single-Modality Treatment?
A single-modality treatment refers to the use of one procedure at a time to improve acne scars.
Each treatment works through a specific mechanism — either releasing tethered scars, stimulating collagen, resurfacing the skin, or restoring lost volume.
At Sozo Aesthetic Clinic, common single treatments include:
| Treatment | Description | Cost |
|---|---|---|
| Subcision | Releases tethered scars causing skin depressions | From $400/session |
| TCA CROSS | Remodels deep ice-pick scars using targeted chemical reconstruction | From $300/session |
| Fractional CO₂ Laser | Resurfaces the skin and smooths boxcar/rolling scars | From $450/session |
| Pico Laser | Improves PIH/brown marks and texture linked to scarring | From $150/session |
| INFINI Fractional RF | Microneedling radiofrequency for deeper collagen remodelling | From $850/session |
| EndyMed FSR | Nano-fractional RF for shallow rolling/boxcar scars | From $500/session |
| Polynucleotide | Injectable skin healer that supports scar repair | From $500/session |
Pros of Single-Modality Treatment
- Focused and targeted — Single treatments address one scar type directly, such as subcision for rolling scars or TCA CROSS for ice-pick scars. Designed to target specific scar types, though outcomes depend on individual assessment.
- Easier to plan and undergo — With only one procedure, planning is simpler. Patients avoid the complexity of combining treatments and feel more comfortable knowing exactly what to expect during each session.
- Shorter recovery per session — Recovery is usually quicker, often just a few days. This makes it suitable for patients who cannot take long breaks from work, studies, or social activities.
- More affordable per session — Since only one treatment is done at a time, each session costs less. Patients can spread expenses gradually, making it easier to manage financially over multiple visits.
- A good first step — Single-modality treatment is a commonly used approach for first-time patients under medical supervision to see how their skin responds before committing to more intensive or combined treatment plans.
Cons of Single-Modality Treatment
- Limited results for mixed scars — Most patients have different scar types. A single treatment may only improve one, leaving other scars untreated, resulting in uneven or less satisfying results overall.
- Slower improvement — Because only one issue is addressed at a time, noticeable progress takes longer. Patients may require many more sessions compared to combination plans to see visible change.
- Risk of plateau — Results from single treatments can stall after a point. Without addressing other scar causes, patients may stop seeing progress despite repeated sessions of the same treatment.
- Less dramatic results — Improvements from single treatments are often subtle. While helpful for mild scars, patients with deeper or mixed scarring may not achieve the dramatic changes they expect.
- Doesn’t treat all causes — Acne scars can involve tethering, collagen loss, and texture irregularities. A single treatment usually targets just one factor, leaving other underlying issues unresolved.
What Is Combination Treatment?
Combination treatment uses two or more procedures in the same session or across several visits to target different aspects of acne scars.
Since most patients present with mixed scar types, a combination approach often provides more complete results.
Examples at Sozo include:
| Combination Treatment | Description | Cost |
|---|---|---|
| Subcision with Fillers for Acne Scars | Releases tethered scars and restores support under the skin | From $400 for Subcision + $600–$1000 per syringe for fillers |
| TCA CROSS with Fractional CO₂ Laser | Remodels both deep ice-pick scars and surface boxcar/rolling scars | From $300 for TCA CROSS + $450 for Fractional CO₂ Laser |
| INFINI Fractional RF with Polynucleotide | Stimulates collagen and supports dermal healing | From $850 for INFINI + $500 for Polynucleotide |
| Pico Laser with EndyMed FSR | Addresses pigmentation/PIH and texture at different skin layers (often alternated across visits) | From $150 for Pico + $500 for EndyMed |
Pros of Combination Treatment
- Treats different scar types at once — Combination therapy tackles rolling, boxcar, and ice-pick scars together, providing more balanced results by addressing multiple scar patterns within a single treatment plan.
- More noticeable results — Using different methods together creates a synergistic effect. This means improvements are more visible compared to single treatments. Patients may find this approach aligns better with their treatment goals.
- Fewer total sessions — By addressing several scar issues simultaneously, combination therapy often reduces the total number of visits needed, making treatment journeys more efficient and results visible more quickly.
- Longer-lasting change — Correcting multiple scar causes, such as tethering and texture. Improvements may last longer in certain cases, depending on skin type and severity.Patients often enjoy improvements that are more durable and natural-looking overall.
- Customised to each patient — Combination treatment gives doctors flexibility to design tailored plans. This allows adjustments for scar type, skin tone, downtime tolerance, and goals, ensuring results meet individual expectations.
Cons of Combination Treatment
- Higher upfront cost — Because multiple treatments are performed, the initial cost per session is higher. However, this investment often balances out by achieving better results in fewer total sessions.
- On average, longer recovery time — Combining treatments usually means more redness, swelling, or bruising. Some pairings have similar downtime to single treatments, but overall recovery is typically a little longer.
- More complex planning — Not all treatments can be done together safely. Some require careful sequencing across weeks was or months, making treatment journeys more structured and sometimes harder to schedule consistently.
- Higher risk of side effects — With more treatments in one plan, side effects like redness, pigmentation, or temporary irritation may be more likely, though usually manageable with proper aftercare.
- Greater commitment required — Combination plans often involve multiple visits, longer sessions, and more aftercare. Patients need to commit time and effort to follow the plan closely for best results.
How Doctors Decide
At Sozo, Dr. Justin Boey will provide you with the best treatment advice — whether to use multiple treatments in combination or a specific single procedure tailored to your scars.
All chosen based on your scar type, skin tone, downtime tolerance, and goals.
- Assessing Scar Types and Severity – different scars need different treatments, and most patients have a mix.
- Considering Skin Type and PIH Risk – medium to darker skin tones (Fitzpatrick III–V) are more prone to pigmentation; safer parameters and devices are used.
- Balancing Lifestyle and Downtime – treatment is matched to each patient’s schedule and recovery tolerance.
- Taking Budget and Goals Into Account – whether the patient prefers gradual improvement or faster results shapes the plan.

Frequently Asked Questions (FAQ)
How do I know if I need a single treatment or a combination plan?
The choice depends on your scar type, skin tone, and goals. A consultation with a doctor is the best way to decide, as most patients have a mix of scars.
Can I start with single treatments and move on to a combination later?
Yes. Many patients begin with single-modality treatments to test how their skin responds, then transition into a combination plan for more complete results.
Do combination treatments always mean more downtime?
Not always. Some combinations, like subcision with filler, may have a similar recovery time to a single treatment. Others, like laser plus TCA CROSS, may extend healing slightly longer.
Will I get faster results with combination treatments compared to single treatments?
In most cases, yes. Combination therapy often produces visible changes more quickly, since multiple scar types are treated at the same time.
