You might start paying closer attention to your skin in certain lighting.

Some areas may stand out more than others.

Most people don’t begin by asking about CO2 laser.

The conversation usually starts during a consultation, when skin concerns are discussed more broadly.

CO2 laser may be introduced as one of several options.

This usually happens when a practitioner is assessing more established or complex concerns.

This is not a casual or a low-commitment treatment.

It involves proper assessment, planning, and time for recovery.

Before getting into how it works, it helps to understand what it actually is and how it’s used in practice.

What is CO2 laser resurfacing?

CO2 stands for carbon dioxide. In cosmetic medicine, it refers to a type of ablative laser used in clinical settings.

It delivers controlled energy to the skin, which affects both the surface and deeper layers.

You can think of it as a treatment that works in two ways at once.

It removes portions of the outer skin, while also heating the layers underneath.

This is part of how the skin responds over time.

Most modern devices use what’s called fractional technology.

The laser is applied in a grid-like pattern, so only small sections of skin are treated at a time.

The surrounding skin is left untouched between treated areas.

Due to the way the laser affects the skin, CO2 laser is usually considered within a broader treatment plan.

A clinician will assess suitability based on factors such as skin type, medical history, and the nature of the concern.

What does CO2 laser address

CO2 laser resurfacing may be discussed during consultation when people bring up certain skin concerns.

These are often concerns that involve differences in skin texture or visible irregularities on the surface

A clinician may consider it in cases such as:

• acne scarring
• surgical scars
• sun-related skin concerns or uneven pigmentation
• fine lines and deeper-set lines
• mild to moderate skin laxity
• uneven texture
• enlarged pores

Each of these concerns can present differently from person to person.

For example, acne scarring can vary in depth and shape, while pigmentation may sit at different levels within the skin.

CO2 is an ablative laser.

This means it creates controlled areas of impact on the skin by removing portions of the outer layer and delivering controlled heat into deeper layers.

The effects on the skin can vary depending on the type of concern being assessed.

This is why treatment planning is not standardised and is based on clinical evaluation.

CO2 laser for acne scars

Acne scarring is one of the concerns that may be discussed in relation to CO2 laser.

Acne scarring often involves differences beneath the surface of the skin.

Fractional CO2 laser is sometimes considered when assessing acne scarring because of how these scars sit within the skin.

Some scars create uneven surfaces, while others form deeper indentations.

The treatment approach depends on how these scars present.

In some cases, multiple sessions may be discussed, or alternative options may be considered as part of a broader plan.

Not all acne scars are suited to the same approach.

This is why assessment focuses on scar type, skin type, and how the skin presents over time.

Who is CO2 laser for?

Not everyone who asks about CO2 laser will be suitable for this treatment.

Some people come in with different expectations around treatment and recovery time.

While others are already aware that this type of treatment may involve planning and a period of downtime.

It often comes down to how the skin presents, their comfort with the recovery period, and whether the treatment fits within their broader preferences.

CO2 laser resurfacing may be appropriate for:

• Individuals with visible textural concerns
• Patients who understand and accept downtime
• Those exploring non-surgical treatment options

It may not be suitable for:

• Certain skin types with higher risk of pigmentation changes
• Patients on specific medications
• Individuals whose expectations may not align with clinical advice
• Those unable to commit to strict aftercare

At Ascension, suitability is determined following medical consultation and skin assessment. Treatment recommendations are always individualised.

The CO2 Laser Process: From consultation to aftercare

1. Medical Consultation

Under current Australian regulations, a thorough consultation is required before the treatment. This includes:

• Full medical history
• Skin assessment
• Discussion of risks and what the procedure involves
• Review of alternative options
• Clear explanation of the recovery process

No treatment should proceed without informed consent.

2. Preparation Phase

Patients may be advised to:

• Cease certain skincare products
• Begin skin preparation protocols
• Avoid sun exposure
• Use prescribed topical products where appropriate

Preparation steps vary depending on individual factors and the planned treatment.

3. Treatment Day

CO2 laser resurfacing is performed in a controlled clinical environment.

A topical anaesthetic may be applied. Treatment time varies depending on the area treated.

Because this is an ablative laser, it may include redness, swelling, and a sensation of heat.

4. Recovery and Downtime

Recovery is an expected part of the process following CO2 laser treatment.

The extent and duration can vary depending on the individual and the area treated.

Common post-treatment responses may include:

• redness
• swelling
• oozing or crusting
• peeling
• temporary skin sensitivity

Downtime can vary from person to person.

Some people may require a period away from usual activities while the skin recovers.

Aftercare instructions are provided as part of the treatment process. These may include:

• use of prescribed post-procedure products
• limiting sun exposure
• use of high-SPF sun protection
• gentle cleansing

Following aftercare guidance is part of the overall management of the skin during recovery.
