A doctor-level patient guide grounded in the 2024 international acne scar consensus, AAD guidance and Malaysian dermatology practice — matched to Asian (Fitzpatrick III–V) skin.
Direct answer
No single treatment wins for everyone — match the tool to the scar type. For most KL patients: subcision + fractional CO₂ for rolling/boxcar scars, TCA CROSS for icepick scars, and RF microneedling as the safer first-line for medium-dark Asian skin. Expect 3–6 sessions across 4–8 months for 50–70% improvement. Only see a registered dermatologist or MOH LCP Chapter 1 doctor.

Match to your scar type
The 2024 acne scar consensus (JAAD) and AAD both stress: identify the scar type first, then pick the tool.
Best evidence: TCA CROSS
Focal 70–100% TCA rebuilds collagen inside the pit. AAD-cited standard.
Best evidence: Subcision + fractional CO₂ (or RF microneedling)
Subcision releases tethered bands; laser/RF remodels the surface. Strongest 2024 consensus evidence.
Best evidence: Fractional CO₂ or RF microneedling
Ablative or fractionated heat resurfaces the edge. RF microneedling preferred for darker skin.
Best evidence: Intralesional steroid ± 5-FU
Different pathway — flatten with injections, not resurfacing lasers. Requires an experienced doctor.
Best evidence: Topicals + pico laser
Not a scar — a pigment issue. Sunscreen + azelaic/tranexamic acid + gentle pico usually enough.
Side-by-side
Fractional CO₂ · RF microneedling · Subcision · TCA CROSS
| Attribute | Fractional CO₂ | RF microneedling | Subcision | TCA CROSS |
|---|---|---|---|---|
| Best for | Deep rolling & boxcar | Rolling & boxcar in darker skin | Rolling (tethered) | Icepick |
| Sessions | 1–3 | 4–6 | 3–4 | 3–5 |
| Downtime | 5–10 days | 2–4 days | 2–5 days (bruising) | 3–7 days scabbing |
| PIH risk (Fitz IV–V) | Higher | Lower | Low | Moderate |
| KL price / session | RM1,200–2,500 | RM900–2,000 | RM400–900 | RM300–700 |
Most real protocols in KL combine 2–3 of these — e.g. subcision at session 1, then RF microneedling at sessions 2–4, with TCA CROSS spot-treatment on icepick scars in between.
Verify before you book
In Malaysia, subcision, TCA CROSS, fractional CO₂ and RF microneedling can only legally be performed by a registered doctor with the MOH LCP Chapter 1 credential (or a dermatologist). Beauticians and spa therapists cannot perform any of these. Check any doctor's status in 5 seconds — free.
