How Co2 Fractional Laser Works

The carbon dioxide laser (CO2) uses short pulses of laser light to precisely remove the outer layers of wrinkled, acne-scarred, aged or sun-damaged skin. The procedure creates controlled microscopic wounds, triggering your skin’s natural healing response, which involves the growth and remodeling of new collagen fibers. Fractionated laser treatment delivers laser energy in tiny, closely spaced dots, treating only a portion (or “fraction”) of your skin at a time. By adjusting the density (how close or far apart these dots are placed), the laser carefully targets specific areas, minimising heat and damage to the surrounding healthy skin and allowing quicker recovery compared to traditional full-field Co2 laser treatments. You can watch Dr Josh explain fractional laser here.

Key points to understand about this skin resurfacing treatment include:

  • Co2 Laser beams precisely resurface damaged skin layer by layer
  • Only a fraction of the skin is treated at a time resulting in less social downtime than traditional full-field ablative lasers
  • Stimulates collagen production, with the goal of improving skin texture, skin tone, and overall skin quality
  • Can target the full face or specific treatment areas like eyes, mouth, neck, forehead or scars anywhere on the body
  • Can be performed under local anaesthesia blocks or topical numbing cream for patient comfort. Nitrous Oxide gas (happy gas) is also available for use if clinically indicated for analgesia management

What are the Benefits of CO2 Laser Treatment

CO2 fractional laser resurfacing is a recognised treatment option in cosmetic dermatology aimed at improving skin texture, tightness, clarity, and overall appearance. Many patients consider this procedure due to its proven potential for noticeable improvements following just one session, although individual results and longevity of effects vary. Here’s why it is frequently requested:

Wrinkle Reduction

  • May assist in reducing the appearance of deeper wrinkles and expression lines, such as those around the eyes, lips, and forehead.
  • Can help improve the appearance of smoker’s lines and crow’s feet, with results depending on individual skin types and concerns.

Skin Texture Improvement

  • Aims to enhance skin smoothness by addressing rough or uneven skin texture.
  • Can help refine the appearance of enlarged pores and promote overall improved skin appearance.

Acne & Surgical Scar Treatment

  • Can help reduce the visibility of acne, chickenpox, surgical, or traumatic scars.
  • Supports natural skin remodeling by stimulating collagen production.

Skin Firmness and Tone

  • Aims to support improved skin firmness through stimulation of collagen in deeper skin layers.
  • May offer subtle lifting effects in areas prone to laxity, including cheeks, jawline, neck, and under-eye areas.

Pigmentation Improvement

  • May assist in reducing the appearance of pigmentation issues, including sunspots and uneven skin tone.

Preparing for Your CO2 Laser Procedure

Proper preparation is important before undergoing CO2 fractional laser treatment. Following preparation guidelines may help minimise risks and support the skin’s natural healing process. Individual healing experiences and outcomes vary.

  • Avoid sun exposure for at least two weeks before your procedure. UV damage increases the risk of pigmentation changes and can slow the healing process. Daily use of a broad-spectrum SPF 50+ is recommended, even on cloudy days.
  • Discontinue active skincare ingredients such as retinoids, alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), benzoyl peroxide, and exfoliating scrubs at least 7 to 10 days before treatment. These products can increase skin sensitivity and the chance of irritation.
  • Stop smoking ideally one to two weeks prior to treatment. Smoking impairs circulation and oxygen delivery to the skin, which can delay healing and compromise your results. This includes vaping.
  • Inform your clinician about your full medical history, especially if you have a history of cold sores (herpes simplex virus), as antiviral medication may be recommended to reduce the risk of a flare-up. Let your doctor know if you have a history of keloid scarring, delayed healing, or if you’re taking any medications that could impact the skin’s response.
  • Avoid blood-thinning supplements or medications such as fish oil, vitamin E, aspirin, or anti-inflammatories like ibuprofen for three to five days before your session, unless prescribed for a medical condition. Always check with your GP or prescribing doctor before stopping any medications.
  • A topical anaesthetic cream will be applied approximately 45 minutes before the procedure to numb the skin and reduce discomfort during treatment. If you are treated with a Contour Clinics doctor, the option of local anaesthetic may be provided if clinically indicated.
  • Preparing your skin with the use of a brightening creme 2 times/day for 2 weeks prior to treatment can decrease the risk of post inflammatory hyperpigmentation after treatment. We recommend the brightening creme from ilumae. This is especially necessary for those with darker skin types.
  • Support your skin barrier in the days leading up to your appointment by using a gentle cleanser and a non-active moisturiser. This helps minimise irritation and improves post-treatment recovery.
  • Arrive with clean, product-free skin. If you have any active infections, cold sores, or skin irritations in the treatment area, your appointment may need to be postponed for safety reasons.

Patient Journeys

What to Expect During CO2 Laser Resurfacing

CO2 fractional laser resurfacing typically takes 30 to 60 minutes, depending on the treatment area and intensity of Co2 settings. Smaller areas (like under-eyes or upper lip) may take 20–30 minutes; full-face or combined face and neck sessions can take up to an 90 minutes.

After cleansing the skin, topical anaesthetic applied 45–60 minutes prior ensures adequate numbing. Your clinician will then pass a fractional CO2 laser across the skin, creating thousands of microscopic thermal columns. This removes damaged outer layers and stimulates deep collagen remodelling. Fractional lasers deliver controlled micro-injuries to a fraction of the skin, leaving surrounding tissue untouched. This triggers a natural healing process where healthy skin cells migrate into the treated areas, stimulating regeneration and creating fresh, rejuvenated skin.

Patients typically feel heat, tingling, or a mild stinging sensation. Discomfort is minimised with anaesthetic and integrated cooling systems.

Immediate post-treatment effects include:

  • Redness similar to a moderate sunburn
  • Mild to moderate swelling, especially around the eyes
  • Pinpoint bleeding or oozing, depending on treatment depth
  • Residual heat or skin tightness for several hours

A cooling gel or occlusive dressing may be applied post-treatment. You’ll receive tailored aftercare instructions to support healing and minimise complications.

When treating specific areas, careful consideration of the surrounding skin is essential to prevent visible lines of demarcation and ensure a smooth, natural result. For this reason, we frequently recommend treating the neck and décolletage simultaneously, creating an even, blended appearance between treated areas and the surrounding skin.

Recovery and Aftercare from Co2 Laser

The healing process after CO2 fractional laser resurfacing is a critical phase that directly impacts your final results. Proper aftercare helps reduce downtime, prevents complications, and ensures smoother, healthier skin renewal.

After your Co2 laser, the skin will appear red, swollen, and may feel tight or warm—similar to a severe sunburn. This is a normal inflammatory response and typically peaks within the first 48–72 hours. It is crucial to apply protective barrier creams (we recommend dermeze ointment) to freshly treated skin to prevent dehydration and infection.

  • Redness and swelling generally subside within 3 to 14 days, depending on the treatment depth and individual healing response. Pinpoint scabbing or peeling is common and part of the natural resurfacing process.
  • Mild weeping or crusting may occur in the first few days, especially after deeper treatments or when larger areas are treated.

Key Aftercare Instructions

  • Apply the occlusive moisturiser Dermeze (available in clinic or at your local pharmacy) multiple times daily to protect the skin and prevent trans epidermal water loss.
  • Cleanse gently with a non-foaming, non-fragranced cleanser starting 24–48 hours post-treatment, as directed by your clinician.
  • Do not pick or peel flaking skin, as this may lead to scarring or pigmentation.
  • Avoid sun exposure entirely for a minimum of 2–4 weeks post-treatment. Always wear a broad-spectrum SPF 50+ and wide-brimmed hat if outdoors. UV exposure during healing increases the risk of post-inflammatory hyperpigmentation.
  • Refrain from using makeup until your clinician confirms that your skin barrier is fully healed—typically after 7–10 days.
  • Avoid active skincare ingredients (including retinol, AHAs, BHAs, and vitamin C serums) until the skin has fully re-epithelialised and any residual redness has resolved. Reach out to your Contour Clinics practitioner if you are unsure.
  • Focus on hydration and barrier repair using calming, fragrance-free products specifically designed for post-procedure skin.

When to Contact Us

Mild discomfort, redness, and swelling are expected. However, you should promptly contact your provider if you experience:

  • Signs of infection (increasing pain, pus, spreading redness)
  • Delayed healing or new lesions
  • Persistent weeping or excessive crusting beyond 10–14 days

Most complications following CO2 laser resurfacing can be effectively managed with minimal long-term impact when identified and treated early, before they progress into more serious concerns.

Results and Maintenance After CO2 Laser Resurfacing

CO2 fractional laser resurfacing may provide noticeable improvements in skin appearance. When performed by qualified clinicians and combined with proper aftercare, potential results can develop progressively over time.

Initial skin improvements typically become visible within 7–14 days, though individual experiences vary. Potential outcomes may include:

  • Reduced fine lines and deep wrinkles
  • Refined skin texture and tone
  • Faded pigmentation, sun damage, and scars
  • Improved skin firmness and elasticity

Results may continue to improve for 3–6 months post-treatment as newly formed collagen fibres strengthen and remodel. This delayed improvement is one of the key benefits of fractional laser resurfacing, offering long-term skin rejuvenation that evolves gradually over time.

Longevity of Results

Individual results and the duration of improvements from CO2 resurfacing vary. Maintaining a healthy lifestyle, following appropriate skincare routines, and avoiding factors like sun exposure and smoking can help support prolonged results

Protecting Your Investment

To prolong the effects of your CO2 laser treatment:

  • Practice strict sun protection, including daily application of a broad-spectrum SPF 50+, wearing wide-brimmed hats, and avoiding peak UV exposure.
  • Avoid tanning beds and unnecessary sun exposure, especially in the first 6–12 months following treatment.
  • Adopt a supportive skincare regimen, including antioxidants, gentle exfoliants, peptides, and hydrating products to maintain skin health and barrier function.

Maintenance Treatments

While CO2 laser resurfacing provides a significant reset to your skin, maintenance is key to keeping your results fresh. Popular adjunctive treatments include:

Frequently Asked Questions

Is CO2 laser resurfacing safe?

All medical procedures carry risks, which will be thoroughly explained to you in the context of your individual health and treatment goals.

CO2 laser resurfacing is a powerful dermatology grade technology that has been around in various incarnations for decades. Improvements in delivery of CO2 energy have improved the safety profile of CO2 resurfacing, resulting in potentially less risk of complication, and shorter, more palatable downtimes, without sacrificing results.

CO2 resurfacing is a powerful procedure requiring appropriate clinical expertise. Potential risks include prolonged downtime, infection, unwanted pigmentation changes, and increased skin sensitivity. Qualified medical oversight of CO2 procedures is essential to optimise safety and outcomes.

Who is Co2 laser treatments most suitable for?

CO2 laser treatment is most suitable for individuals with moderate to severe skin concerns such as:

  • Deep wrinkles and fine lines
  • Acne scars or surgical scars
  • Uneven skin tone and texture
  • Sun damage and pigmentation issues
  • Skin laxity, particularly around the eyes and mouth

It’s most appropriate for fair to medium skin tones, as darker skin types may have a higher risk of post-inflammatory hyperpigmentation. Suitable candidates are generally in good health, not prone to keloid scarring, and prepared to undergo a few days to two weeks of downtime depending on the intensity of the treatment. An initial consultation with a qualified practitioner is essential to assess individual suitability and to create a personalised treatment plan based on your skin type and concerns. Individual results and experiences may vary.

Who is not a candidate for Co2 laser?

CO2 laser resurfacing is a recognised cosmetic treatment; however, it may not be suitable for everyone. Factors affecting suitability may include:

  • Darker skin types (Fitzpatrick V–VI): May carry an increased risk of pigmentary changes such as post-inflammatory hyperpigmentation or hypopigmentation. Alternative treatments may be considered.
  • History of keloid or hypertrophic scarring: Could affect the skin’s response to treatment.
  • Active acne, infections, or open skin lesions: Treatment should generally be postponed until the skin has healed.
  • Pregnancy or breastfeeding: Treatment is typically not recommended during these times.
  • Recent oral isotretinoin (e.g., Roaccutane) use within 6 months: May increase potential risks related to wound healing.
  • Uncontrolled medical conditions (such as diabetes or autoimmune diseases): These conditions may influence skin healing and treatment suitability.
  • Difficulty adhering to aftercare and sun protection guidelines: Proper aftercare significantly impacts outcomes.

A thorough skin and medical assessment by a qualified clinician is essential prior to undergoing CO2 laser resurfacing to determine individual suitability. Individual outcomes and experiences vary.

How much does Co2 laser resurfacing cost?

The cost of CO2 laser resurfacing depends on factors including the treatment area and clinician providing the treatment. Treatments performed by a doctor start at $2995 for the full face, whereas those performed by a nurse or dermal therapist start from $2195 for a full face. See link to full Co2 laser price list. Doctor-performed procedures typically involve options not available with other practitioners, including:

  • Ability to perform nerve blocks for enhanced patient comfort, especially during more intensive treatments.
  • Ability to use intra-ocular eye shields, enabling safe treatment closer to the eyelid area.
  • More intensive treatment settings, potentially reducing the number of sessions needed.
  • Access to certain prescription-based aftercare treatments under medical supervision.

Smaller, targeted treatments, such as scar management, are priced individually according to the specific area and patient requirements.

Individual pricing and treatment recommendations are provided during a comprehensive consultation. Individual results, experiences, and recovery times may vary.

Is Co2 laser worth the money?

CO2 laser resurfacing can involve a higher upfront cost compared to other skin treatments. However, many patients consider it valuable due to its potential to address multiple skin concerns, including wrinkles, pigmentation, acne scars, and mild skin laxity, in fewer sessions. Whether it is worth the investment depends on your individual skin goals, expectations, and personal budget. Results and satisfaction vary significantly among individuals, so it is important to discuss your goals with a qualified clinician during a consultation to determine if this treatment aligns with your expectations and financial considerations.

How much does Co2 laser for under eye bags cost?

Co2 laser under the eyes to treat eye bags or wrinkling starts from $700. If the entire skin of the eye lid (upper or lower) needs to be treated intra-ocular shields must be placed which is performed by one of our doctors. The fee for this is $1200.

What is the downtime for a Co2 laser resurfacing?

CO2 laser resurfacing typically involves 3 to 14 days of downtime, depending on the intensity of the treatment and your individual healing response. Here’s a general timeline for a moderate settings treatment:

  • Days 1–3: Redness, swelling, and a sensation similar to a deep sunburn. Oozing and crusting are normal.
  • Days 4–7: Skin begins to peel and regenerate. Strict aftercare is essential to prevent infection and support healing.
  • Days 7–10: Most of the visible peeling subsides. Redness may persist but can be covered with makeup if cleared by your clinician.
  • Weeks 2–4: Redness fades gradually. You can return to most normal activities, but sun protection is critical.
  • Months 1–3: Skin texture, tone, and overall quality continue to improve as collagen remodelling takes place.

Your exact recovery will depend on your skin type, the depth of the treatment, and how well you follow post-treatment care instructions.

How painful is Co2 laser?

CO2 laser resurfacing can be uncomfortable, but the level of pain depends on the depth of treatment, area being treated, and your individual pain threshold.

At Contour Clinics, we ensure your comfort by using a combination of:

  • Topical anaesthetic cream applied prior to treatment
  • Local anaesthetic injections for deeper resurfacing or sensitive areas like under the eyes
  • Nitrous Oxide (Laughing Gas) provided it is clinically indicated for analgesia management

During the procedure, patients often describe the sensation as a hot, prickling or stinging feeling. After treatment, it can feel like a moderate to intense sunburn for the first 24–72 hours.

Pain is usually most noticeable in the first 48 hours, then significantly subsides as healing progresses. We provide detailed aftercare and pain relief strategies to help you recover comfortably.

What will my face look like after Co2 laser?

Immediately after CO2 laser resurfacing, your face will appear red, swollen, and feel sunburned, with possible pinpoint bleeding or oozing depending on the depth of treatment. This is completely normal and indicates the skin’s natural healing response.

Here’s what you can expect day by day:

  • Day 1–3: Intense redness, swelling, and a hot or tight sensation. You may see oozing or crusting in treated areas. Skin will begin to feel dry and tight.
  • Day 4–7: Skin starts to flake and peel as new layers emerge. Redness begins to fade. Most patients feel comfortable resuming light activities by day 5.
  • Day 8–14: The majority of visible peeling resolves. Pinkness may persist but can be covered with makeup (if approved by your clinician).
  • Weeks 2–6: Skin tone continues to even out. Collagen production ramps up, improving firmness and texture.
  • Months 2–6: Results peak as deeper collagen remodeling completes, revealing smoother, clearer, and more youthful skin.

It’s essential to follow your aftercare routine, avoid sun exposure, and use barrier creams to support healing and prevent complications.
