CO2 Laser for Large Pores: What Actually Works
CO2 laser for large pores is one of the most common questions we hear from clients walking into our Brisbane clinics. Enlarged pores are a structural feature of the skin, not built-up dirt, so scrubs and pore strips only ever offer a temporary fix. This guide explains how CO2 laser actually works on pore size, what results are realistic, and what the process looks like from first consultation to final results.
What Is CO2 Laser for Large Pores?
CO2 laser for large pores uses a carbon dioxide laser to remove a thin layer of damaged surface skin and heat the tissue underneath. This controlled process signals the skin to rebuild itself with fresh collagen. As the collagen network strengthens, the skin surrounding each pore opening tightens, so pores can look smaller and less obvious.
Fractional CO2 devices treat skin in thousands of tiny columns rather than the entire surface at once. This leaves untreated skin between each column, which supports faster healing. Full-face sessions and smaller, targeted areas such as the nose or cheeks are both options, depending on where pores are most visible.
What Causes Enlarged Pores?
Pore size is largely set by genetics, so no treatment changes the underlying opening completely. However, several other factors make pores look bigger over time, and understanding them explains why collagen-focused treatments tend to outperform surface-level products.
Genetics
Baseline pore size and skin thickness are inherited, and this sets a natural floor on how small pores can appear.
Sun damage & ageing
UV exposure and age gradually reduce collagen, so pores lose their support and stretch open.
Excess oil production
Oilier skin types often show more visible pores, particularly through the T-zone.
Acne scarring
Past breakouts can leave pores looking wider and the surrounding texture uneven.
How CO2 Laser Reduces Pore Size
CO2 laser energy targets water in the skin at a 10,600nm wavelength. This wavelength is well absorbed by skin tissue, which allows precise removal of the damaged outer layer with minimal spread to the surrounding area.
Underneath the surface, the controlled heat activates fibroblasts — the cells responsible for collagen production. Over the following weeks, new collagen fibres form around each pore opening and gradually add support to the surrounding skin.
A peer-reviewed study on laser treatment for enlarged pores reported pore-size reductions in the range of roughly 15 to 40 percent following a course of fractional laser sessions, though individual results vary with pore severity, skin type, and how many treatments are completed.
Key Facts
- Wavelength used: 10,600nm, targeted at water in the skin
- Typical course: 1 to 3 sessions, spaced several weeks apart
- Downtime: generally 5 to 7 days for fractional settings
- Reported outcomes in published research: roughly 15–40% reduction in pore visibility
What to Expect: The Treatment Process
Consultation & skin assessment
Pore severity, skin type, and any contraindications are reviewed before a treatment plan is confirmed.
Cleansing & topical numbing
Numbing cream is applied roughly 30–45 minutes before treatment to keep the session comfortable.
Laser passes
Your practitioner moves the CO2 device across the treatment area in a controlled pattern, adjusting depth to match your pore severity.
Cooling & soothing mask
A calming mask is applied immediately afterward to settle heat in the skin.
Aftercare instructions
You’ll leave with a written care plan covering cleansing, moisturising, and sun protection for the healing period.
CO2 Laser vs Other Pore Treatments
CO2 laser isn’t the only option for enlarged pores, and it isn’t always the right starting point. The table below compares it with other treatments we offer, including Pico Laser, which some clients prefer for milder pore concerns alongside pigmentation.
| Treatment | Downtime | Sessions Typically Needed | Best Suited For |
|---|---|---|---|
| CO2 Laser (fractional) | 5–7 days | 1–3 | Moderate to significant pore enlargement, texture, mild scarring |
| Microneedling | 1–2 days | 4–6+ | Mild pore concerns, sensitive or darker skin tones |
| Pico Laser | Minimal | 4–6 | Pigmentation alongside mild pore concerns |
| Chemical Peel | 0–3 days | 3–6 | Superficial texture, ongoing maintenance |
Recovery and Results Timeline
Redness and warmth, similar to mild sunburn, are common immediately after treatment.
Skin may feel tight and begin to dry out or flake as it heals.
Peeling completes for most clients, revealing fresh skin underneath.
Residual redness continues to fade and pore appearance starts to refine.
Collagen remodelling continues, and most of the visible pore improvement appears in this window.
Pore refinement from CO2 laser is a gradual process, not an overnight change, and it isn’t permanent — ongoing sun protection and skincare help maintain results over time. For a fuller breakdown of the healing process, see our CO2 fractional resurfacing treatment page.
Safety Considerations and Who Should Avoid It
CO2 laser is well-tolerated by most skin types when settings are matched to your skin, but it isn’t right for everyone. A consultation helps identify whether it, or a gentler alternative, is the better starting point for your pores.
- Have active acne breakouts, cold sores, or an open skin infection in the treatment area
- Have very dark skin, where the risk of post-inflammatory pigment change is higher and conservative settings or a patch test may be recommended
- Are pregnant or breastfeeding
- Have a history of keloid scarring or slow wound healing
About LLC Cosmetic Laser Clinics

Frequently Asked Questions
Does CO2 laser get rid of large pores completely?
No. Pore openings are a natural, genetically-determined part of the skin, so no treatment removes them entirely. CO2 laser may help reduce how visible they appear by building collagen around each opening.
How many CO2 laser sessions do I need to see pore improvement?
Most clients complete 1 to 3 sessions, spaced several weeks apart, depending on pore severity and skin type. Your practitioner will confirm a plan at consultation.
What causes pores to look larger over time?
Genetics sets your baseline pore size, while sun exposure, ageing, excess oil, and past acne scarring all contribute to pores looking more visible over time.
Is CO2 laser or microneedling better for enlarged pores?
CO2 laser generally suits moderate to significant pore concerns and delivers more visible change per session, while microneedling suits milder concerns or sensitive and darker skin types that need a gentler approach.
How long do CO2 laser pore results last?
Results are not permanent, since pore size is influenced by ongoing collagen loss. Consistent sun protection and a maintenance skincare routine help extend the improvement.
Can CO2 laser help oily or acne-prone skin?
CO2 laser is not recommended during active breakouts, but it may be considered once acne is under control. It’s often used to address the textural scarring that acne leaves behind, alongside enlarged pores.
What is the downtime for CO2 laser pore treatment?
Fractional CO2 settings typically involve 5 to 7 days of visible redness and peeling. Deeper settings can extend this window, which your practitioner will discuss before treatment.
CO2 laser treatment for large pores works best as part of a broader skin plan rather than a single fix — realistic expectations, the right settings for your skin, and consistent aftercare all shape the outcome.
