Fractional CO2 laser treats boxcar acne scars and uneven texture by creating tiny columns of controlled injury that the skin repairs with new collagen. At my clinic a single session starts from $390, with a few days of redness, swelling and flaking. It is one modality in a rotated course, not a stand-alone cure. Active breakouts are treated first, as set out in acne treatment in Singapore.
Which acne scars fractional CO2 laser treats
Acne scars form when deep inflammation destroys collagen in the dermis. The causes are explained in what causes acne scars. The shape of the scar decides whether fractional CO2 is the right tool.
- Boxcar scars respond best. Their flat floor and steep edges are softened as new collagen forms.
- Rolling scars improve once subcision has released the fibrous bands tethering them. Laser alone cannot lift a tethered scar.
- Ice pick scars are too narrow and deep for the laser to reach their base. They are treated with TCA CROSS first, and fractional CO2 then refines the texture around them.
- Raised hypertrophic and keloid scars are not treated with fractional CO2. See keloid treatment in Singapore.
Most faces carry a mixture of all three depressed types, which is why fractional CO2 usually forms one part of a six-month plan.
What is fractional CO2 laser and how the Edge fractional CO2 laser works
The CO2 fractional laser treatment uses an ablative laser to improve the appearance of acne scars, fine lines, wrinkles, and uneven texture. It works by creating microscopic treatment zones (MTZs) within the skin, allowing for skin resurfacing and the stimulation of collagen and elastin production, while leaving the surrounding tissue intact for faster healing.
The fractional CO2 laser treatment emits tiny, fractionated beams of laser energy, creating microscopic columns of controlled injury in the skin. This triggers the body’s natural healing and repair mechanisms, stimulating collagen production. This process encourages the skin to repair and regenerate, leading to the rejuvenation of the treated areas and visible improvements in texture, tone, and a reduction in the appearance of scars, wrinkles, and other imperfections.
By treating only a fraction of the skin at any one time, the surrounding healthy tissue remains intact. This significantly reduces downtime and promotes faster recovery compared to traditional CO2 lasers.
Fractional CO2 for Acne Scars and Pigmentation
The CO2 laser works to break down tough scar tissue and stimulate the deep production of new collagen. Simultaneously, it exfoliates pigmented cells from the surface, making it an excellent scar removal option for smoother, more even skin tone.
Fractional CO2 for Enlarged Pores
This CO2 laser treatment helps to tighten the existing skin and encourages new collagen growth around the pores. This supportive structure reduces the visibility of enlarged pores, giving the skin a more refined appearance.
Fractional CO2 for Wrinkles and Fine Lines
The laser delivers controlled energy deep into the dermis, reactivating the body’s collagen-building mechanisms. As new collagen forms, skin firmness and elasticity improve, which visibly reduces the appearance of wrinkles and fine lines.
What fractional CO2 laser treats, acne scars, pores, fine lines and pigmentation
The fractional CO2 laser treatment is highly effective for multiple common skin concerns in Singapore, helping to rejuvenate the skin by promoting collagen renewal and resurfacing.
- Acne scars: Targeting the pitted and uneven texture left behind by previous acne breakouts, the laser stimulates collagen remodelling for smoother skin.
- Fine lines and wrinkles: By resurfacing the skin, the treatment works to diminish the appearance of superficial lines and deeper creases, contributing to a more youthful complexion.
- Age spots and sun damage: The laser reduces hyperpigmentation caused by sun exposure and ageing, leading to a more even skin tone.
- Enlarged pores: Fractional CO2 can help to minimise the appearance of enlarged pores, refining the skin’s surface texture.
- Surgical scars: This treatment can improve the texture and appearance of certain surgical scars, making them less noticeable.

Who is fractional CO2 laser suitable for
Fractional CO2 laser is generally safe and effective for most skin types and tones. However, this procedure may not be recommended for individuals who are pregnant or breastfeeding, have active skin infections, or are prone to keloid scarring. This is because the treatment can potentially interfere with healing, exacerbate skin conditions, or increase the risk of unwanted side effects in these specific situations. Therefore, it is recommended that you consult with a professional to determine your suitability and discuss any potential risks.
Raised scars that grow beyond the original wound are keloids, a different problem from the pitted scars above. See my guide to keloid scars and the options for keloid treatment in Singapore.
With all types of lasers, from Vbeam lasers for vascular lesions to Q-switch Nd YAG lasers for pigmentation, it is crucial to consult with a trained professional like Dr. Gerard Ee. He will conduct a personalised consultation to identify your acne scar types and customise a treatment plan to address your specific needs and achieve optimal results.
What to expect during fractional CO2 laser treatment
The fractional CO2 laser treatment is designed to be as comfortable and effective as possible. The process follows a 4-step procedure to ensure a safe and personalised experience.
- Consultation & Skin Assessment: Dr Ee evaluates your skin concerns to confirm the appropriate treatment parameters and discuss your goals.
- Preparation: Your skin will then be cleansed thoroughly, and a topical numbing cream will be applied to the treatment area to minimise any discomfort.
- Laser Application: The fractional CO2 laser is applied to the affected areas, delivering precise laser energy to the targeted areas.
- Immediate Post-Treatment Effects: You may feel mild redness, warmth, or slight swelling. Cooling will be applied immediately after the procedure for comfort.
Recovery and results after fractional CO2 laser
After the treatment, you may experience some redness, swelling, and mild discomfort for a few days.
The results of Edge Fractional CO2 laser treatment are typically noticeable within a few weeks. However, it may take several months for the full effects to be visible. Multiple treatment sessions may be required to achieve optimal results.
While the Edge Fractional CO2 laser is generally safe and effective, there are some potential side effects, including:
- Redness and swelling: This is a common side effect that usually subsides within a few days.
- Crusting: The treated area may develop crusts, which should not be picked or scratched.
- Pigmentation changes: Temporary changes in skin color may occur, but they usually fade over time.
- Infection: Proper aftercare is essential to prevent infection.

Frequently Asked Questions About Fractional CO2 Laser Treatment in Singapore
Is fractional CO2 laser treatment painful?
Most patients describe the sensation as a mild to moderate stinging or prickling. However, Dr. Gerard Ee applies a topical numbing cream before the treatment to minimise discomfort. He may also use cooling devices after the procedure to enhance your comfort.
When will I start seeing results after the treatment?
With fractional CO2 laser, you may notice some initial improvements in skin texture and tone within a few days. However, the most significant results, including scar removal, usually appear gradually over several weeks as your skin heals and produces new collagen. However, the exact timeline for scar removal varies depending on individual factors and the specific condition being addressed.
How many sessions of fractional CO2 laser will I need?
The number of fractional CO2 laser sessions needed depends on the individual and the severity of the skin concerns. During your consultation, Dr Gerard Ee will assess your skin and recommend a personalised treatment plan. Most patients generally see noticeable improvement after 3-6 sessions, but deeper scar removal or more severe issues may require additional treatments as every individual’s skin and response to the laser are different.
How can I prepare for the treatment?
To prepare for fractional CO2 laser, avoid sun tanning for at least three days prior and do not have a sunburn at the time of treatment. You should also discontinue the use of retinoids and exfoliating products as advised by Dr. Gerard Ee. He will provide you with detailed pre-treatment instructions during your consultation.
What is the fractional CO2 laser treatment experience like
A typical fractional CO2 laser session with Dr. Gerard Ee takes approximately 30-60 minutes. The procedure begins with cleansing the skin and applying a topical numbing cream. Dr. Gerard Ee then uses the fractional CO2 laser on the targeted areas. You may feel a warm or prickling sensation during the treatment. Please feel free to let Dr. Ee know if you experience any discomfort. After the procedure, a cooling device may be used to soothe the skin and minimise your discomfort.
What is the recovery time after the Fractional CO2 laser treatment?
The average downtime for the fractional CO2 laser treatment is typically 5 to 7 days. During this period, you will experience redness, swelling, and the development of tiny scabs in the treated area. The skin will peel away, revealing new, healthier skin underneath. Full healing, including the fading of residual pinkness, continues over the following weeks.
Do I need to stop isotretinoin before fractional CO2 laser?
No. Isotretinoin does not need to be stopped before Infini, Secret RF, fractional CO2 or Fraxel. The six-month wait rests on case reports from the 1980s. Current guidelines and randomised trials find fractional lasers and RF microneedling safe during and immediately after a course, and treating scars while the acne is controlled gives an earlier result. Only fully ablative, non-fractional laser and mechanical dermabrasion are still not recommended on isotretinoin, and fractional CO2 is neither. The evidence is set out in how effective microneedling is for acne scars.
