Acne Scar Removal in KL: Pico Laser vs CO2 Laser — Which Is Right for You?
Acne scar removal is one of the most searched aesthetic concerns in Kuala Lumpur, and for good reason — acne scars affect a significant proportion of the Malaysian adult population and can persist for years without targeted treatment. Two of the most effective technologies available today are Pico Laser and Fractional CO2 Laser. This guide compares both in detail so you can make an informed decision.
Understanding Acne Scar Types
Before comparing treatments, it is important to understand that not all acne scars are the same. The most common types are:
Atrophic Scars (Depressed) — These are the most prevalent type and include ice-pick scars (deep, narrow channels), boxcar scars (wider depressions with defined edges), and rolling scars (gradual, wave-like depressions). All three types respond to laser treatment, though the optimal approach varies.
Post-Inflammatory Hyperpigmentation (PIH) — Dark marks left after acne inflammation. These are not true scars (no structural damage to the dermis) but are often confused with them.
Hypertrophic and Keloid Scars (Raised) — Less common in acne, these raised scars require different treatment approaches and are not the primary focus of this comparison.
How Pico Laser Works for Acne Scars
Pico Laser delivers ultra-short pulses of energy in picoseconds, creating a photoacoustic effect that shatters pigment particles and generates pressure waves in the dermis. These pressure waves stimulate collagen and elastin production without causing significant thermal damage to surrounding tissue.
Best suited for: Mild to moderate atrophic scars, PIH, and patients who need minimal downtime. Pico Laser is particularly effective for the pigmentation component of acne scarring and for patients with darker skin tones (Fitzpatrick III–V) where the risk of post-laser hyperpigmentation is higher with ablative treatments.
Typical results: 40 to 60% improvement in scar appearance after a full course of 4 to 6 sessions.
Downtime: Minimal — mild redness for a few hours, no significant peeling or wound healing required.
How Fractional CO2 Laser Works for Acne Scars
Fractional CO2 Laser is an ablative treatment that uses carbon dioxide laser energy to create thousands of microscopic treatment zones in the skin. The laser vaporises damaged tissue in these zones while leaving surrounding skin intact to accelerate healing. This triggers a robust wound-healing response and significant collagen remodelling.
Best suited for: Moderate to severe atrophic scars, particularly boxcar and rolling scars. CO2 Laser is considered the gold standard for deep structural scar remodelling.
Typical results: 60 to 80% improvement in scar appearance after 2 to 4 sessions.
Downtime: Significant — 5 to 7 days of redness, swelling, and skin peeling. Patients typically need to take time off work.
Side-by-Side Comparison
| Factor | Pico Laser | Fractional CO2 Laser |

| Best for | Mild–moderate scars, PIH | Moderate–severe scars |
| Sessions needed | 4 to 6 | 2 to 4 |
| Downtime | Minimal (hours) | 5 to 7 days |
| Pain level | Mild | Moderate (numbing applied) |
| Risk on dark skin | Low | Moderate |
| Starting price (KL) | From RM 399/session | From RM 499/session |
| Results timeline | 3 to 6 months | 3 to 6 months |
Which Treatment Is Right for You?
Choose Pico Laser if:
- Your scars are mild to moderate
- You cannot afford significant downtime
- You have darker skin (higher PIH risk with ablative lasers)
- Your primary concern is PIH or pigmentation rather than structural scarring
- You want a gradual improvement over multiple sessions
Choose Fractional CO2 Laser if:
- Your scars are moderate to severe with significant depth
- You can commit to 5 to 7 days of downtime per session
- You want the most aggressive structural remodelling available
- You have lighter skin (lower PIH risk)
Consider a combination approach if:
- You have both deep structural scars and significant PIH
- Your doctor recommends starting with CO2 for structural improvement, then Pico for pigmentation refinement

At Medicyto Clinic in Kota Damansara, we offer both Pico Laser and Fractional CO2 Laser (Dermablate) for acne scar removal. Our doctors conduct a thorough skin assessment to determine which treatment — or combination of treatments — will deliver the best outcome for your specific scar type and skin tone.
Pricing starts from RM 399 per session for Pico Laser and RM 499 per session for Dermablate CO2 Laser. Package pricing is available for patients committing to a full treatment course.
Frequently Asked Questions
Can I combine Pico Laser and CO2 Laser? Yes, but not in the same session. A common protocol is to complete a course of CO2 Laser first for structural remodelling, then follow with Pico Laser sessions to address residual pigmentation and refine texture.
How many sessions will I need? This depends on your scar severity. Mild scarring may respond well to 3 to 4 Pico Laser sessions. Moderate to severe scarring typically requires 2 to 3 CO2 Laser sessions, potentially followed by Pico Laser for refinement.
Is laser safe for Malaysian skin? Yes, when performed by an experienced doctor who correctly calibrates the laser for your skin type. Darker skin tones (Fitzpatrick III–V) require lower fluence settings and longer intervals between sessions to minimise PIH risk.
When will I see results? Initial improvements are visible within 4 to 8 weeks of the first session. Full results from a complete treatment course typically manifest within 3 to 6 months as collagen remodelling continues.
