Is CO₂ laser suitable for all skin types?

Lighter skin types (Fitzpatrick I–III) are traditionally better candidates. Darker skin carries higher pigmentation risk — an experienced laser practitioner must assess suitability.

CO₂ laser vs microneedling — which is better for acne scars?

Moderate-to-severe atrophic scars often respond better to fractional CO₂ than standard microneedling. Mild texture concerns may not need laser-level intervention.

What Is CO2 Laser Resurfacing?

CO₂ laser resurfacing uses carbon dioxide laser energy to remove or fractionally ablate skin layers, triggering collagen remodelling. It treats acne scars, texture, fine lines and sun damage. Fractional mode has shorter downtime than fully ablative treatment.

How CO₂ laser works

CO₂ lasers emit energy at 10,600 nanometres — absorbed by water in skin cells. This creates controlled thermal injury that removes damaged tissue and stimulates new collagen over the following months.

Fractional delivery treats columns of skin while leaving bridges intact, speeding recovery. Fully ablative treatment removes the entire surface layer in the treated zone.

Fractional vs fully ablative

Fractional CO₂ suits many acne scar and rejuvenation cases with roughly 5–10 days of downtime. Fully ablative gives more dramatic resurfacing but may need 2–3 weeks of significant recovery.

Your practitioner should match modality to your skin type, concern and tolerance for downtime.

What downtime should you expect?

Expect redness, swelling and peeling after fractional treatment. Sun protection is critical for months afterwards. Fully ablative recovery is more intensive — plan time off work and social commitments.

How many sessions?

Acne scarring often needs 2–3 fractional sessions spaced months apart. Some rejuvenation goals may be met in 1–2. Your clinic should set expectations at consultation.
