CO2 Laser Resurfacing: How It Works, Benefits, and What to Expect

What Is CO2 Laser Resurfacing?

CO2 laser resurfacing is a treatment that uses carbon dioxide laser energy to create controlled treatment areas within the skin.

The laser removes small amounts of skin tissue, initiating the body’s natural healing response and supporting collagen remodelling. As the skin heals, this process may help improve the appearance of certain skin concerns.

Fractional CO2 technology treats small sections of the skin while leaving surrounding areas untreated, supporting the healing process.

What Can CO2 Laser Resurfacing Treat?

CO2 laser resurfacing may be used to address several common skin concerns, including:

• Fine lines and wrinkles: May help reduce the appearance of certain lines and wrinkles.

• Scars: May improve the appearance of some types of scarring, including acne scars.

• Uneven skin texture: Can help address roughness and irregular skin texture.

• Sun damage: May improve certain visible signs of sun-related skin changes.

• Skin irregularities: May be considered for selected textural concerns following a professional assessment.

• Rosacea: May be suitable for managing certain rosacea-related symptoms following an individualized professional assessment.

The suitability of CO2 laser resurfacing depends on individual skin characteristics, the concerns being addressed, and a professional assessment.

How Does CO2 Laser Resurfacing Work?

Fractional CO2 laser resurfacing delivers controlled laser energy into small treatment zones within the skin.

This process removes small amounts of tissue and stimulates the skin’s natural healing response, encouraging collagen remodelling over time.

As the treated skin heals, patients may notice gradual changes in skin texture and appearance. The extent of improvement varies depending on the treatment performed and individual skin characteristics.

What Makes CO2 Laser Resurfacing Different From Other Laser Treatments?

Not all laser treatments work in the same way. Different technologies interact with the skin differently, and the most appropriate treatment depends on the concern being addressed.

CO2 laser resurfacing is an ablative laser treatment, meaning it removes controlled amounts of skin tissue to stimulate the skin’s natural healing process and collagen remodelling.

Other laser treatments may be non-ablative, meaning they deliver energy into the skin without intentionally removing its surface.

CO2 laser resurfacing is often associated with a more involved recovery process than many non-ablative laser treatments. However, treatment intensity and recovery vary depending on the technology, settings, and individual patient.

The main difference between laser treatments is not simply their intensity, but how they interact with the skin and which concerns they are designed to address.

How Does CO2 Laser Resurfacing Compare to Other Skin Treatments?

Several in-clinic treatments may be considered for concerns such as uneven skin texture, fine lines, acne scars, and visible signs of sun damage.

Although these treatments may address some of the same concerns, they work in different ways.

Non-Ablative Fractional Lasers

Non-ablative fractional lasers create controlled treatment zones within the skin without intentionally removing the skin’s surface. They may be used to address concerns such as skin texture, fine lines, and certain types of scarring.

Erbium Laser Resurfacing

Erbium laser resurfacing is another form of ablative laser treatment. Like CO2 resurfacing, it removes controlled amounts of skin tissue. However, the technologies differ in how their energy interacts with the skin, which can influence treatment characteristics and recovery.

Microneedling and Radiofrequency Microneedling

Microneedling creates small, controlled injuries in the skin to stimulate a healing response. Radiofrequency microneedling also delivers heat energy into the tissue.

These treatments may be considered for certain concerns involving skin texture and acne scarring, although their mechanisms differ from CO2 laser resurfacing.

IPL (Intense Pulsed Light)

IPL uses broad-spectrum light rather than a laser. It is commonly used to address certain pigmentation concerns, sun-related discolouration, and visible blood vessels.

While IPL and CO2 laser resurfacing may both be considered for aspects of sun-damaged skin, they target different concerns and work through different mechanisms.

How Often Can You Have CO2 Laser Resurfacing?

There is no single CO2 laser treatment schedule that applies to everyone.

Depending on individual skin concerns and treatment goals, some patients may undergo a series of CO2 laser treatments, while others may consider additional treatments at a later date.

The number of treatments and the time between appointments depend on several factors, including:

• The patient’s starting skin condition

• The concerns being addressed

• Individual treatment goals

• The intensity of the treatment

• The skin’s response and recovery

• Other treatments included in the patient’s skincare plan

For some patients, CO2 laser resurfacing may be considered alongside other in-clinic treatments and an ongoing at-home skincare routine.

The need for repeat treatments and the appropriate timing should be determined through a professional assessment. Annual treatments are not necessary or suitable for everyone.

What to Expect During CO2 Laser Treatment

Before treatment, a consultation allows a healthcare professional to assess the skin, discuss individual goals, and determine whether CO2 laser resurfacing is appropriate.

The treatment process varies depending on the area being treated and the selected treatment settings.

Patients will receive guidance on preparation, the treatment process, and recommended aftercare.

What Is Recovery Like After CO2 Laser Resurfacing?

Recovery varies depending on the intensity of treatment and individual skin characteristics.

Temporary effects may include:

• Redness

• Swelling

• Skin sensitivity

• Peeling or flaking

• Changes in skin appearance during healing

CO2 laser resurfacing also carries potential risks, including pigmentation changes, infection, and scarring.

Following post-treatment instructions and protecting the skin from sun exposure are important during recovery.

When Will Results Be Visible?

Changes in skin appearance may become noticeable as the skin heals following treatment.

Additional improvements may develop gradually as collagen remodelling continues over time.

Results depend on individual skin characteristics, the treatment performed, and the concerns being addressed. Some patients may require additional treatments to work toward their goals.

Is CO2 Laser Resurfacing Right for Everyone?

CO2 laser resurfacing is not suitable for every skin type, skin concern, or individual.

Factors such as medical history, skin characteristics, pigmentation risk, and treatment goals should be considered before proceeding.

A professional consultation can help determine whether CO2 laser resurfacing is an appropriate option.
