Summary
- Acne scars form when the skin produces too little or too much collagen after a deep breakout, leaving behind pits, depressions, or raised marks that don’t fade on their own.
- Not all acne scars are the same, brown marks (PIH), red marks (PIE), and depressed scars each need a different laser: Picoway, Vbeam, or Fractional CO₂ respectively.
- Laser treatment works by stimulating collagen production and resurfacing the skin, which also tends to improve texture, pore size, pigmentation, and early signs of ageing along the way.
- Most patients need 3 to 5 sessions spaced 4 to 6 weeks apart, with downtime ranging from under 24 hours (Picoway/Vbeam) to 3 to 7 days (CO₂ laser), depending on the treatment used.
What Are Acne Scars and Why Do They Form?
Acne scars are permanent textural changes left behind after deep inflammation or cystic acne has damaged the skin. They form when the skin’s healing process produces either too little collagen (atrophic scarring) or too much (hypertrophic scarring), and the type of scar you have determines which treatment will actually help.
What Are The Types of Acne Scars?
There are 4 main types of acne scars:
- Ice pick
- Rolling
- Boxcar
- Hypertrophic / Keloid
| Type | Appearance | Typical Treatment |
|---|---|---|
| Ice pick | Deep, narrow, pitted scars | Fractional CO₂ laser, TCA CROSS |
| Rolling | Undulating, wave-like indentations | Subcision + CO₂ laser + RF microneedling |
| Boxcar | Broad, rectangular depressions | CO₂ laser, fractional resurfacing |
| Hypertrophic / Keloid | Raised, firm scars | Vbeam / corticosteroid injections |
What Is Laser Treatment for Acne Scars?
Laser treatment for acne scars is a medical-grade procedure that uses focused light energy to improve the appearance of scarring by resurfacing the skin and stimulating new collagen production underneath it. Rather than simply treating the surface, it works on rebuilding the skin’s structure from within.
Beyond scar improvement, laser treatment also tends to enhance:
- Skin texture
- Pigmentation
- Pore appearance
What Types of Acne Scars Can Be Treated with Laser?
Acne scars aren’t a single condition, and treatment needs to match the type of scarring involved, using the wrong laser for the wrong scar type is one of the most common reasons people don’t see results.
Brown Marks (Post-Inflammatory Hyperpigmentation)
- Not true scars, but a common after-effect of acne
- Show up as dark spots, particularly in Asian skin
- Treatment: Picoway laser
- Breaks down pigmentation
- Improves overall skin tone
- Downtime: minimal, with redness typically clearing within 24 hours
Red Marks (Post-Inflammatory Erythema)
- An early-stage mark that appears as acne heals
- Shows up as red or pink discolouration
- Treatment: Pulsed dye laser (Vbeam)
- Targets the blood vessels causing the redness
- Reduces redness noticeably
- Fading is often visible after just 2–4 treatments
- Downtime: minimal, with 1–2 days of mild redness
Depressed Acne Scars (Atrophic Scars)
- Includes ice pick, boxcar, and rolling scars
- Caused by collagen loss in the deeper layers of skin
- Treatment: Advanced fractional laser system (Smartxide Fractional CO₂ laser)
- Creates controlled columns of laser injury in the deeper layers of skin
- Stimulates new collagen production to plump and smooth the area
- Helps resurface and restore collagen, reducing the appearance of depressions and textural irregularities
- Downtime: 3–7 days of redness or flaking
- Session frequency: 3–5 sessions, every 4–6 weeks
How Does Laser Treatment for Acne Scars Work?
Laser treatment for acne scars helps:
- Stimulates new collagen production beneath the skin’s surface
- Resurfaces damaged, uneven skin
- Breaks down excess pigmentation
- Improves overall texture and tone
Improvement builds gradually with each session rather than appearing overnight, which is why a structured course of treatment tends to outperform a single one-off session.
If acne is still active alongside the scarring, it’s worth addressing both, take a look at our acne treatment page for how we approach active breakouts before or alongside scar treatment.
Comparison of Laser Treatments for Acne Scars
The table below compares different laser treatments for acne scars based on the main concerns they address, deep scars, pigmentation, and redness, as well as how they work and their expected downtime.
| Concern | Treatment | How It Works | Downtime |
|---|---|---|---|
| Deep scars | CO₂ Laser | Collagen stimulation & resurfacing | Moderate |
| Pigmentation | Picoway Laser | Breaks down pigment | Minimal |
| Redness | Vbeam Laser | Targets blood vessels | Minimal |
What to Expect During Laser Acne Scar Treatment
During the scar laser treatment session:
- A consultation and scar assessment with Dr Stephanie Ho
- Application of numbing cream, left on for 30–45 minutes before treatment begins
- Treatment itself typically takes 20–45 minutes, depending on the area being treated
Aftercare
- Mild redness or swelling for 2–5 days is normal
- Avoid makeup and direct sun exposure immediately after treatment
- Apply prescribed recovery creams and SPF daily during recovery
What Results Can I Expect from Laser Acne Scar Treatment?
- Improvement happens gradually, not immediately
- Multiple sessions are generally required to see full results
- Alongside scar improvement, most patients also notice better skin texture, smaller-looking pores, more even pigmentation, and softening of fine lines, revealing smoother, fresher-looking skin overall
Laser acne scar treatment delivers gradual improvements rather than immediate results. Multiple treatment sessions are generally required to achieve the best possible outcome, as the skin needs time to heal and regenerate between sessions. In addition to reducing the appearance of acne scars, many patients also notice improvements in overall skin texture, smaller-looking pores, more even pigmentation, and softened fine lines. Over time, these changes can contribute to smoother, more even, and fresher-looking skin overall.

Frequently Asked Questions (FAQs)
What triggers acne scars?
Acne scars are triggered by deep, inflamed breakouts, particularly cystic acne, that damage the skin’s structure below the surface. As the skin attempts to heal itself, it can produce either too little collagen, leaving a depression, or too much, leaving a raised mark. The deeper and more inflamed the original breakout, the more likely it is to leave a lasting scar.
What makes acne scars worse?
Picking or squeezing active breakouts is one of the most common causes of worsened scarring, as it increases inflammation and skin trauma. Sun exposure without adequate protection can also darken post-acne marks and delay fading, while leaving active acne untreated for long periods gives more time for deeper scarring to form.
Does laser treatment remove acne scars permanently?
Laser treatment can significantly and lastingly improve the appearance of acne scars by rebuilding collagen and resurfacing the skin, though results vary depending on scar depth and type. Very deep scars may see substantial improvement rather than complete disappearance, which is why an accurate assessment of your scar type matters before starting treatment.
Which laser is best for acne scars?
There isn’t a single “best” laser, because different scar types respond to different technologies. Picoway is generally used for pigmentation-related brown marks, Vbeam targets redness from post-inflammatory erythema, and Fractional CO₂ laser is typically used for depressed, textural scarring.
Is Picoway laser effective for acne scars?
Picoway is particularly effective for the brown, pigmented marks that often follow acne, especially in Asian skin, as it works by breaking down excess pigmentation. It’s less suited to textural, depressed scarring, which usually responds better to a fractional laser instead.
How many sessions are needed?
Most patients need between 3 and 5 sessions, spaced 4–6 weeks apart, though this depends on the type and severity of scarring being treated. A personalised assessment during your consultation will give you a clearer idea of what to expect for your specific case.
Is laser acne scar treatment safe?
When performed by a trained dermatologist using appropriate settings for your skin type, laser treatment for acne scars is considered a safe, well-established procedure. This is particularly important for Asian skin, which carries a higher risk of pigmentation changes if the wrong laser or settings are used.
Is Laser Treatment for Acne Scars Painful?
Most patients describe the sensation as mild discomfort rather than significant pain, and numbing cream is applied beforehand to keep the procedure comfortable. Some treatments, particularly CO₂ laser, may feel more intense than others like Picoway or Vbeam.
How much does laser treatment for acne scars cost in Singapore?
Cost depends on the type of laser used, the number of sessions required, and the size of the area being treated, so pricing varies from patient to patient. A consultation is the best way to get an accurate estimate based on your specific scarring.
When is it too late to treat acne scars?
There’s generally no point at which acne scars become untreatable, even years after the original breakouts have healed. That said, earlier treatment tends to be more straightforward, and addressing scarring while it’s still relatively recent can sometimes mean a shorter course of treatment.
