Acne scars remain one of the most frustrating and difficult skin concerns worldwide. Even in 2026, patients still struggle with deep ice-pick scars, rolling scars, uneven texture, and pigmentation after acne.
Fortunately, treatment technology has evolved significantly—especially fractional lasers and combination therapies. This guide explains what actually works, which method fits each scar type, and how clinics can choose the right device.
As we explore various options for acne scar treatment 2026, it’s vital to understand how advancements in technology are making these treatments more effective for various scar types.
For those seeking solutions, acne scar treatment 2026 offers the latest advancements in skin repair and rejuvenation.
Acne Scar Treatment 2026
Before choosing any treatment, correctly identifying the scar type is essential:
Ice-pick scars
Deep, narrow, and resistant to mild treatments. They require aggressive collagen remodeling such as CO2 fractional laser.
Boxcar scars
Well-defined edges; moderate to deep. Respond well to CO2, 1550nm, or subcision.
Rolling scars
Shallow and undulating. Best treated with RF microneedling or 1550nm laser.
Post-inflammatory hyperpigmentation (PIH)
Not a true scar—a type of discoloration. Best treated with 1927nm Thulium or chemical peels.
Why this matters:
➡ Laser choice depends entirely on scar depth.
➡ Wrong treatment = poor results.
1. Fractional Laser Treatments (best laser for acne scars)
Fractional lasers remain the gold standard in 2026 due to their ability to rebuild collagen and resurface deep textural irregularities.
CO2 Fractional Laser – Best for Deep, Severe Scars
- Wavelength: 10,600nm
- Ablative (removes tiny columns of skin)
- Strong collagen stimulation
- Best for: ice-pick, deep boxcar, surgical scars
- Downtime: 5–7 days
CO2 fractional lasers deliver dramatic improvements with as few as 1–2 sessions.

1550nm Erbium Glass Laser – Best for Medium-Depth Scars
- Non-ablative
- Lower downtime (1–3 days)
- Penetrates deeply without vaporizing skin
- Best for: rolling scars, moderate boxcar scars
- Typically requires 3–5 sessions
👉 Comparing CO2 vs 1550 acne scars?
1927nm Thulium Laser – Best for Pigmentation & Superficial Texture
- Targets the epidermis and upper dermis
- Excellent for PIH, mild scars, discoloration
- Minimal downtime
- Often combined with 1550nm in the same session

2. RF Microneedling (Best for Rolling & Mixed Scars)
2026’s RF microneedling devices use insulated needles to deliver heat deep into the dermis. This tightens tissue and lifts rolling depressions.
Benefits:
- Safe for all skin types
- Good for shallow–moderate scars
- Improves texture and skin laxity
- skin resurfacing treatment
- Minimal pigmentation risk
RF microneedling is often combined with lasers for stronger results.
3. Subcision (Must-Have for “Tethered” Scars)
Some acne scars are physically attached to deeper tissue by fibrotic bands.
These must be broken manually through subcision, or lasers won’t lift the scar.
Best combined with:
- Hyaluronic acid fillers
- CO2 fractional laser
- RF microneedling
Subcision + CO2 remains one of the strongest combinations in 2026.
4. Chemical Peels (Supportive Treatment)
Not strong enough for deep scarring, but useful for:
- Surface roughness
- Hyperpigmentation
- Post-acne redness
Common combinations include 1927nm + superficial peel.
5. Combination Therapy (Most Effective in 2026)
The most successful acne scar strategies use multiple technologies:
Top combinations used in 2026:
- Subcision + CO2 fractional laser
- RF microneedling + 1550nm
- 1927nm + CO2 light resurfacing
- CO2 + PRP for enhanced healing
- 1550nm + chemical peels
Combination treatment provides:
- Faster improvement
- Better texture correction
- Smoother overall skin tone
Most patients require 3–6 months for full results.
How to Choose the Right Treatment
Deep Scars (ice-pick, deep boxcar)
✔ CO2 fractional
✔ Subcision + CO2
✔ TCA CROSS for ice-pick
Medium Scars (rolling, moderate boxcar)
✔ 1550nm
✔ RF microneedling
✔ Subcision if tethered
Mild Scars & Pigmentation
✔ 1927nm
✔ Chemical peels
✔ Combination with 1550nm
FAQ (Search-Friendly Section)
How long do acne scar results last?
Results are long-lasting because collagen remodeling is permanent.
Is CO2 “too aggressive”?
CO2 is safe when performed by trained professionals and remains the most effective treatment for deep scars.
Can darker skin types use lasers?
1550nm and RF microneedling are safer options. CO2 can be used with caution and correct parameters.
How many sessions do I need?
- CO2: 1–2
- 1550nm: 3–5
- RF microneedling: 3–6
- 1927nm: 4–8
