At London Medical and Aesthetic Clinic, we provide one of the most effective non-surgical treatments available for improving the appearance of scars: fractional CO2 laser resurfacing. Using the advanced SmartSkin Performa CO2 laser, first introduced to the UK and Europe by Dr Ayham Al-Ayoubi, our clinic has become a leading centre for laser-based scar revision and skin regeneration.
Scars can be the result of surgery, injury, acne, burns or trauma, and they can affect both the texture and tone of the skin. Fractional CO2 laser resurfacing is one of the few treatments capable of improving scars at both the surface and deeper layers, stimulating new collagen and smoothing irregularities. With precise control and minimal downtime, this treatment helps scars become softer, flatter and more blended with the surrounding skin.
Why Choose CO2 Laser for Scar Revision?
Scars often form when collagen fibres heal in a disorganised or uneven pattern, leaving raised, indented or rough skin. Topical creams and light treatments can offer limited improvement because they cannot reach the deeper layers where structural changes are needed.
Fractional CO2 laser resurfacing works by creating microscopic treatment zones within the scar tissue, breaking down dense or fibrotic areas while stimulating healthy collagen to rebuild the structure. This dual action helps soften raised scars, lift depressed scars and smooth irregular texture. Over time, the treated area becomes more even, less noticeable and better matched to the surrounding skin. For patients looking for meaningful scar improvement without surgical intervention, CO2 laser treatment is one of the most advanced and proven options available.

Which Types of Scars Can CO2 Laser Treat?
CO2 laser resurfacing can improve many types of scars, including:
- Surgical scars
- Injury or trauma scars
- Acne scars (boxcar, rolling and mixed types)
- Hypertrophic scars (not actively growing)
- Burn scars
- Stretch marks with scar-like texture
- Post-procedure scars
- Scars on the face, body, neck, chest or limbs
Because the laser stimulates deep collagen remodelling, it can be effective for both new and long-standing scars.
How the SmartSkin Performa CO2 Laser Works
The SmartSkin Performa CO2 laser represents the latest generation of fractional resurfacing technology, designed to treat scars with exceptional accuracy and control. Its advanced scanning pattern allows the doctor to place microscopic beams of energy into targeted areas of scar tissue while leaving the surrounding skin untouched. This fractional approach helps maintain the integrity of healthy skin, promoting faster healing and reducing downtime compared with older, fully ablative CO2 lasers. The precision of the SmartSkin system also allows the treatment to be tailored to the depth, density and type of scar being addressed.
The laser works through two primary mechanisms:
1. Micro-Ablation of Scar Tissue
The laser creates tiny columns of controlled micro-ablation within the scar, removing small sections of thickened, damaged or irregular tissue. By breaking up the dense collagen that gives scars their uneven texture, this process helps smooth raised areas, soften rigid scar tissue and reduce surface irregularities. This controlled removal creates space for healthy new tissue to regenerate and gives the scar a more refined and balanced appearance.
2. Deep Collagen Stimulation
In addition to micro-ablation, the laser delivers measured heat into the deeper layers of the dermis, activating fibroblasts and stimulating the production of new collagen and elastin. This deeper remodelling helps strengthen the skin, improve flexibility and gradually rebuild the scar from within. As collagen continues to form over the following weeks and months, scars typically become flatter, smoother and more consistent with the surrounding skin.
Because the SmartSkin Performa system treats only a fraction of the skin at a time, recovery is quicker, while the regenerative effects continue to develop gradually for several months, leading to long-lasting improvement in both texture and appearance.

What to Expect During Treatment
Your treatment begins with a consultation with Dr Ayham Al-Ayoubi, who will assess the scar and recommend the most suitable approach. A topical anaesthetic is applied before the procedure to ensure comfort.
During the treatment, the SmartSkin CO2 laser is passed across the scar using a precise fractional pattern. Patients may feel warmth or a light prickling sensation, but this is generally well tolerated. Protective shields may be used depending on the scar location. Treatment time varies, ranging from a few minutes for small scars to around 45 minutes for larger areas.
Aftercare and Recovery
After treatment, the skin typically feels warm and appears red, similar to a mild sunburn. Mild swelling can occur in the first 24 to 48 hours. Peeling or dryness usually begins between days three and seven as the old skin sheds and fresh tissue appears beneath.
You will be provided with detailed aftercare instructions, which may include:
- Gentle cleansing with sterile water
- Application of a healing ointment
- Avoiding sun exposure during healing
- Using broad-spectrum SPF once the skin allows
- Avoiding active skincare products until advised
Most patients return to normal daily activities quickly, with deeper healing continuing for several weeks.
When Will I See Results?
Early improvement is often noticeable once the initial peeling settles, usually within one to two weeks, when the area looks smoother and more refined. More significant changes develop over six to twelve weeks, as collagen production increases and the scar begins to remodel. The most dramatic improvements often appear between three and six months after treatment, as the new collagen matures.
For deeper or more complex scars, two or three sessions spaced several months apart may be recommended to achieve optimal results.
Is CO2 Laser Safe for Scar Revision?
Fractional CO2 resurfacing is considered safe and reliable when performed by an experienced doctor. The SmartSkin Performa laser allows precise control over energy, depth and density, minimising risks while ensuring effective scar improvement.
Temporary redness, warmth and swelling are expected during the early healing phase. Less common side effects, such as pigmentation changes or delayed healing, are rare when appropriate aftercare is followed. Your treatment plan will be carefully tailored to ensure safety based on your skin type and scar characteristics.

CO2 Laser for Scar Revision – FAQs
How does CO2 laser improve scars?
CO2 laser resurfacing improves scars by creating microscopic treatment zones within the scar tissue, which helps break down thickened or fibrotic areas while stimulating new collagen to replace the damaged structure. This dual action encourages the scar to remodel from the inside out, gradually softening its appearance, smoothing texture, and blending it more naturally into the surrounding skin. Over time, the treated area becomes flatter, less noticeable and more even in tone.
Can CO2 laser treat both new and old scars?
Yes, fractional CO2 laser resurfacing is effective for both new and long-standing scars. Newer scars may respond more quickly due to ongoing collagen activity, while older scars require deeper stimulation to encourage remodelling. The SmartSkin Performa system allows the doctor to adjust settings precisely, making it suitable for a wide range of scar ages, including those that formed many years ago. Regardless of the age of the scar, the laser helps improve texture, depth and discolouration.
Is the treatment painful?
Most patients find CO2 laser scar revision comfortable because a topical anaesthetic is applied before treatment to numb the area. During the procedure, you may feel a warm or prickling sensation as the laser energy is delivered into the skin, but this is generally well tolerated. After treatment, the skin can feel similar to a mild sunburn, with temporary warmth or tenderness that gradually settles over the following days as healing begins.
How many sessions will I need?
The number of sessions required depends on the type, depth and age of the scar. Some superficial scars or smaller surgical scars may show significant improvement after a single session, while deeper or more complex scars often benefit from two or three treatments. Sessions are typically spaced several months apart to allow the skin to fully rebuild collagen between treatments. During consultation, a personalised plan will be recommended based on the nature of your scar.
When will I see results?
Early improvements usually become visible once the initial redness and peeling have settled, often within the first one to two weeks. The most significant changes occur gradually over the next six to twelve weeks as collagen production increases beneath the skin. Scars continue to improve for several months, with the most noticeable benefits often appearing between the three- and six-month mark. Patients with deeper scars may see continued refinements even beyond this period.
What is the downtime after CO2 laser scar revision?
Most patients experience mild redness, warmth and slight swelling immediately after treatment, which usually settles within a day or two. The skin then begins to peel or feel dry around days three to seven as the resurfacing process takes place. During this time, it is important to follow the aftercare advice provided, which may include gentle cleansing, using a protective ointment and avoiding sun exposure. The skin continues to heal and improve for several weeks, with most people returning to normal activities quickly.
Is CO2 laser safe for scar revision?
Fractional CO2 resurfacing is considered safe when performed by a trained and experienced specialist. The SmartSkin Performa system allows precise control over energy and depth, minimising the risk of complications while ensuring effective results. Temporary side effects such as redness, peeling and swelling are expected and settle naturally. Rare complications, including pigmentation changes or prolonged redness, are uncommon when appropriate aftercare is followed and treatment is performed using correct parameters for your skin type.
Can CO2 laser completely remove a scar?
No treatment can guarantee complete removal of a scar, but CO2 laser resurfacing can significantly improve its appearance by smoothing texture, softening raised areas, lifting indentations and reducing discolouration. Many patients see a substantial difference in the visibility of their scar, often making it far less noticeable. The degree of improvement depends on factors such as scar type, depth and age, and a consultation will help determine the most realistic and effective outcome for your specific scar.
How long do the results last?
The results of CO2 scar revision are long lasting because the treatment stimulates the production of new collagen, which strengthens and remodels the skin. Most patients maintain their improvements for many years, especially when they protect the area from sun exposure and maintain a good skincare routine. Although natural ageing continues, the structural improvements created by the laser provide durable benefits, and some patients choose occasional maintenance treatments if they would like further refinement.
