What does CO2 laser resurfacing do?
When people ask me what CO2 laser resurfacing is, I explain that it is a resurfacing treatment rather than a general tightening treatment. The laser removes tiny, controlled areas of the skin surface and creates a thermal effect below them. The untreated skin between the columns helps support the repair process.
The CO2 laser used for resurfacing works at a wavelength of 10,600 nm. Fractional delivery means I treat the skin in microscopic columns rather than removing the entire surface continuously. That allows the treatment to address the texture of the skin while leaving areas between the columns to assist recovery.
As the skin repairs, collagen remodelling takes place in depth. This is why CO2 laser skin resurfacing may be considered for more established texture changes, rather than being used simply as a surface exfoliation treatment.
You can read more about the treatment itself on my CO2 laser resurfacing treatment page.

How does fractional CO2 laser work on the skin?
The word fractional describes the pattern of treatment. Instead of treating every part of the skin in one uninterrupted layer, the laser creates many precise microscopic treatment columns. The intensity, depth and coverage can be adjusted according to the concern, area and your skin.
The outer skin is resurfaced directly, while the controlled heat prompts a wider repair and remodelling response. This is different from energy-based tightening treatments, standard microneedling and needle-based or regenerative approaches. Each works through a different mechanism, so I do not treat them as interchangeable options.
The response is individual. Skin condition, the area being treated, treatment settings, previous procedures and your ability to follow aftercare all form part of my assessment.
What skin concerns can CO2 laser resurfacing address?
CO2 laser for skin resurfacing is commonly discussed when someone wants to improve the appearance of several related concerns, especially where texture is part of the picture. At Naomi Waite Aesthetics, I assess it for concerns including:
- Fine lines and more established wrinkles
- Acne scarring and selected other scars
- Uneven or coarse skin texture
- Enlarged pores
- Sun-related skin ageing
- Some changes in skin laxity where texture and lines are also present
CO2 may also influence the appearance of pigmentation as the skin heals, but it is not always the most direct choice when pigment is the main concern. Pigment-focused options, including IPL, Pico, Q-switched or Thulium laser treatments, may be considered depending on what I see.
For acne scarring specifically, I explain how resurfacing may fit your scar pattern and wider skin goals on my page about CO2 fractional laser for acne scarring.
Is CO2 laser the same as Erbium laser?
Both CO2 and Er:YAG 2940 laser sit within the resurfacing laser group, but they have a different balance between ablation and thermal effect.
Neither is automatically better for every person or every concern. For example, enlarged pores can be linked to different combinations of oil, congestion, ageing, scarring and skin texture. I consider the cause, the area, your skin and the level of resurfacing that is appropriate rather than choosing a device by name alone.
What happens before CO2 laser resurfacing?
Every treatment starts with a consultation. I review your skin, treatment history, concerns, expectations and the recovery time you can realistically allow. I also need to understand any previous laser or light treatments and how your skin has responded.
We discuss whether resurfacing is appropriate, which areas may be treated and what level of treatment is sensible. I will explain the likely skin response and aftercare relevant to your plan. I do not promise a particular result, because collagen remodelling and healing vary between individuals.
Recovery is an important part of the decision. CO2 is more intensive than a non-ablative light treatment because it intentionally resurfaces the outer skin. You should be prepared to follow the aftercare instructions carefully and protect the treated area from unnecessary irritation and sun exposure while it heals. I explain the expected process in detail before treatment, rather than leaving you to work it out afterwards.
