CO2 Laser vs Microneedling
Comparing ablative laser resurfacing with mechanical microneedling
Book ConsultationCO2 laser and microneedling both stimulate the skin’s natural healing response to improve texture, tone, and scarring, but they achieve this in fundamentally different ways. CO2 laser uses ablative energy to vaporise damaged tissue and trigger deep remodelling, while microneedling (SkinPen) creates controlled micro-injuries to stimulate collagen production without removing skin layers. Your choice depends on the severity of your concerns, how much downtime you can afford, and the intensity of results you are seeking.

When We Recommend Each Treatment
Choose CO2 Laser if
- You have deep scarring or significant sun damage requiring intensive treatment
- You want dramatic results from a single session
- You can accommodate 7–10 days of visible recovery
- Your skin type has been assessed as suitable for ablative treatment
Choose Microneedling if
- Your concerns are mild to moderate and you prefer gradual improvement
- You want minimal downtime with each session
- You have a darker skin tone (lower risk of pigmentation changes)
- You prefer a series-based approach with progressive results
Consider combining both when
- You have mixed-depth scarring requiring different treatment intensities
- Dr Langdon recommends a phased approach starting with microneedling
- You want to maintain CO2 laser results with periodic microneedling sessions
Frequently Asked Questions
Can I have both CO2 laser and microneedling?
Yes, the two treatments can complement each other in a staged plan. Microneedling may be used before CO2 laser to prepare the skin, or afterwards as maintenance. Dr Langdon will advise on appropriate sequencing and intervals between treatments.
Which treatment has more downtime?
CO2 laser has significantly more downtime — typically 7–10 days of redness, swelling, and peeling. Microneedling usually involves just 1–2 days of mild redness, similar to mild sunburn. This makes microneedling more practical for those with busy schedules.
Which is better for acne scars?
For deep, pitted acne scars, CO2 laser generally produces more dramatic improvement in fewer sessions. For mild to moderate scarring or post-inflammatory marks, microneedling can deliver excellent results with less risk and downtime. Many patients benefit from combining both approaches.
Is microneedling safer for darker skin?
Yes, microneedling is generally considered safer for darker skin tones (Fitzpatrick types IV–VI) because it is non-ablative and does not use heat energy that could trigger pigmentation changes. CO2 laser requires very careful parameter adjustment for darker skin and carries a higher risk of post-inflammatory hyperpigmentation.
How many sessions will I need?
CO2 laser often achieves significant improvement in a single session, though some patients may benefit from 2–3 treatments. Microneedling typically requires a series of 3–6 sessions spaced 4–6 weeks apart for optimal results. The exact number depends on your concerns and treatment goals.
Not Sure Which Skin Treatment Is Right?
A consultation with Dr Langdon will assess your skin concerns and recommend the most suitable treatment or combination for your goals.
Book Your ConsultationWhich is right for you?
The best treatment depends on your individual concerns, skin type, and goals. Here are some general considerations:
- Choose CO2 laser if you have deep scarring, severe sun damage, or want dramatic results from fewer sessions
- Choose microneedling if your concerns are mild to moderate and you prefer minimal downtime per session
- CO2 laser requires significantly more recovery but typically delivers more intensive results
- Microneedling is generally safer for darker skin tones and carries less risk of pigmentation changes
