Not all acne scars respond to the same treatment. The difference between dramatic improvement and wasted money comes down to matching the right treatment to the right scar type. This guide maps every common acne scar in Malaysia to the evidence-based treatment approach.

Scar Type Determines Treatment, Not the Other Way Around
Acne scars are not all the same. Boxcar scars, rolling scars, ice pick scars, and hypertrophic scars each have different structures, and require different treatment approaches. A laser that works beautifully for rolling scars may not move the needle on an ice pick scar. A good assessment by an experienced doctor identifies your predominant scar type and builds a treatment plan accordingly. Avoid clinics that offer the same laser package to every acne scar patient regardless of assessment.
Understanding Your Scars
Types of Acne Scars: Know What You Have
Correct classification is the foundation of effective treatment.
Rolling Scars
Appearance: Undulating, wave-like surface depressions with gently sloping edges. The skin looks uneven rather than having sharply defined craters.
Cause: Fibrous tethering bands that pull the skin surface down from beneath, creating the "rolling" appearance when skin is stretched or illuminated from the side.
Best treatments: Subcision (to release tethering bands) is the most effective first step, followed by RF microneedling or fractional CO2 laser. Filler can immediately lift depressed areas. Biostimulators (Sculptra, Radiesse) rebuild collagen volume underneath.
Laser alone is moderately effective without subcision, the tethering band limits how much laser-induced collagen can lift the surface.
Boxcar Scars
Appearance: Round or oval craters with sharply defined, steep vertical edges. Resemble the marks left by chickenpox. Shallow boxcar scars are significantly more responsive to treatment than deep ones.
Cause: Significant tissue volume loss at the scar site without the fibrous tethering of rolling scars.
Best treatments: Fractional CO2 laser (best evidence base for boxcar scars), Rejuran S for tissue reconstruction, RF microneedling (Potenza, Sylfirm), filler for immediate volume restoration in deep scars. Punch elevation or excision for isolated deep boxcars.
Excellent laser response for shallow-moderate depth; deep boxcar scars require multiple modalities.
Ice Pick Scars
Appearance: Deep, narrow, sharp-walled pits that extend deep into the dermis or subcutaneous tissue. Resemble the mark of an ice pick or large open pore.
Cause: Deep follicular destruction that creates a narrow channel down into the dermis.
Best treatments: TCA CROSS (Chemical Reconstruction of Skin Scars), applying high-concentration TCA into the narrow pit to stimulate collagen fibrosis and fill the channel from within. Punch excision for isolated severe ice picks.
Fractional CO2 laser alone does not effectively treat ice pick scars, this is one of the most common disappointments in acne scar treatment. TCA CROSS should be done first or simultaneously.
Hypertrophic / Keloid Scars
Appearance: Raised, thickened, firm scar tissue. Hypertrophic scars stay within the original wound boundary. Keloids extend beyond it. Both are more common in Fitzpatrick III–V skin (the majority of Malaysian patients).
Cause: Excessive collagen deposition during healing, opposite of the volume-loss mechanism of atrophic scars.
Best treatments: Intralesional corticosteroid injections (flatten and soften raised scars), pulsed dye laser or Nd:YAG laser (reduce redness and thickness), silicone gel/sheets (evidence-based first-line for prevention and early treatment).
What NOT to do: Fractional CO2 laser on active hypertrophic or keloid scars, high risk of worsening.
Treatment Options
Treatment Options in Malaysia
Six proven modalities, most effective when combined based on scar type.
Fractional CO2 Laser
Creates thousands of microscopic ablative columns in the skin, stimulating dramatic collagen remodelling and resurfacing the skin surface. The most powerful laser tool for atrophic acne scars.
Best for: Boxcar scars (especially moderate depth), rolling scars (combined with subcision), overall skin texture improvement.
Sessions: 2–4 sessions spaced 4–6 weeks apart.
Downtime: 3–7 days (redness, peeling, swelling). Adding exosomes post-laser dramatically reduces downtime.
RM800–3,000 per session
Must be done conservatively on Fitzpatrick III–V skin to avoid PIH. Experienced doctor + correct settings = good outcome.
Pico Laser (Fractional Mode)
In fractional mode, Pico Laser creates photoacoustic micro-injuries (without ablation), stimulating collagen remodelling with less downtime and lower PIH risk than fractional CO2.
Best for: Mild to moderate atrophic scars, post-acne pigmentation (PIH), patients wanting minimal downtime.
Sessions: 4–6 sessions needed; results per session less dramatic than fractional CO2.
Downtime: 1–2 days mild redness.
RM600–2,500 per session
Best combined with fractional CO2 (for deep scars) or standalone for maintenance/mild scars.
Subcision
A fine needle is inserted under rolling scars and moved in a fan-like motion to physically release the fibrous tethering bands that pull the skin surface down. A mechanical release, not a surface treatment.
Best for: Rolling scars, the most effective single intervention for this scar type.
Sessions: 1–3 sessions typically.
Downtime: Bruising for 3–7 days. No ablative downtime.
RM500–1,500 per session
Always most effective when followed by laser or RF microneedling to stimulate collagen in the released space.
RF Microneedling (Potenza, Sylfirm, Morpheus8)
Combination of microneedling with radiofrequency energy delivered at precise depths, triggering dermal collagen remodelling and skin tightening.
Best for: Rolling and boxcar scars with mild-moderate depth; skin texture improvement; patients who cannot tolerate ablative laser downtime.
Sessions: 3–5 sessions, 4–6 weeks apart.
Downtime: 24–72 hours redness and mild swelling.
RM800–2,500 per session
Less PIH risk than ablative laser, particularly Sylfirm X which targets only the dermis without surface damage.
TCA CROSS (Chemical Reconstruction)
High-concentration TCA (80–100%) applied precisely into individual ice pick scars using a toothpick-thin applicator, stimulating focal fibrosis and collagen production from within the scar channel.
Best for: Ice pick scars, the only highly effective treatment for this scar type.
Sessions: 2–4 sessions spaced 6–8 weeks apart.
Downtime: Small white frost at application points resolves in 3–7 days. Very targeted.
RM300–800 per session
Should be performed only by experienced doctors, applying TCA incorrectly can cause additional scarring.
Rejuran S / Exosome / Filler
Rejuran S: Highest-viscosity polynucleotide for scar tissue reconstruction. Exosomes: Post-laser application accelerates healing. Filler: Immediate volume restoration for depressed scars.
Best for: Deep boxcar/rolling scars (filler), post-laser recovery (exosomes), tissue regeneration (Rejuran S).
Sessions: Varies by modality.
Downtime: Minimal for exosomes; 1–3 days for Rejuran S; immediate for filler.
Rejuran S: RM1,200–2,500 | Exosomes: RM500–1,500 | Filler: RM1,500–3,000
HA filler dissolves after 9–12 months. Biostimulators (Sculptra, Radiesse) rebuild collagen longer-term.

Results
What to Expect: Results Timeline
Month 1 (Sessions 1–2)
Initial inflammation and healing. Mild improvement in texture from first session. TCA CROSS begins closing ice pick channels. Subcision releases tethering bands, bruising resolves to reveal flatter skin.
Month 2–3 (Sessions 2–4)
Collagen remodelling accelerates. Progressive improvement in boxcar and rolling scar depth. Skin texture and overall quality improving. PIH (if any) being addressed concurrently.
Month 4–6 (Completing Course)
Most significant visible improvement. New collagen matrix thickening beneath scars. Combination approach showing synergistic results. Photos compared to baseline show meaningful change.
Month 6–12 (Maintenance)
Collagen continues to mature and contract. Results peak. Maintenance sessions (every 3–6 months) sustain improvement. Many patients pursue additional rounds for further improvement.
Candidates
Who Is Acne Scar Treatment For?
Good Candidates

- Patients who have resolved active acne and want to address residual scarring
- Those wanting maximum results, willing to invest in a proper combination programme
- Patients prepared for multiple sessions and realistic timelines
Not Recommended For

- Pregnant or breastfeeding women (most active treatments contraindicated)
- Those with active skin infections at treatment sites
- Patients with keloid-prone skin wanting ablative laser without proper assessment
- Anyone expecting single-session transformation, acne scar treatment is a programme, not a procedure
