Concerns like acne scars, sun damage, deep wrinkles, and uneven skin texture are some of the most common reasons people visit our clinic. At South Yarra Dermatology, fractional CO2 laser is one option we use to improve these conditions by triggering your skin’s natural repair process and boosting collagen production.
CO2 laser treatment uses focused beams of light to remove damaged outer skin layers and encourage deeper renewal. The laser creates tiny columns of treated skin across the area, leaving surrounding tissue untouched to support faster healing. This triggers your body’s natural repair process, prompting fresh collagen growth and new skin cell production.
Our dermatologists adjust the treatment depth and intensity based on your specific concerns and skin type. Modern CO2 lasers technology allows us to achieve significant improvements in skin texture, tone, and scarring while supporting more comfortable healing.

CO2 laser treatment is one of the most effective resurfacing options for significant skin concerns because it works by removing damaged outer layers while stimulating deep collagen remodeling. This dual action of controlled tissue removal and regeneration makes it particularly valuable for concerns that require substantial improvement rather than subtle enhancement. CO2 laser treatment can improve a range of skin concerns, including:
CO2 laser offers benefits from improving acne scars and fine lines to resurfacing sun-damaged skin and stimulating collagen production. Before recommending treatment, we take time to understand what you hope to achieve and how CO2 laser might fit into your treatment goals. This helps us determine the appropriate laser settings and treatment intensity for your skin concerns.
Our dermatologists can adjust the laser settings to match your specific concerns and skin type, treating everything from superficial texture issues to deeper scars with precision.
The treatment triggers your body’s natural healing response, promoting new collagen production that continues to improve your skin’s appearance for months after treatment.
Unlike some cosmetic treatments that require frequent maintenance, CO2 laser results can last for years, particularly when combined with good sun protection and skincare.
A single treatment can improve scarring, wrinkles, pigmentation, and texture at the same time, making it an efficient option for comprehensive skin rejuvenation.
We begin by assessing your skin concerns and medical history to determine if CO2 laser is the right approach. We’ll discuss the treatment intensity needed, the recovery process, and realistic outcomes for your specific concerns.
In the weeks leading up to treatment, we’ll ask you to use specific skincare products and strictly avoid sun exposure. Stop certain medications and supplements that can increase bleeding or affect healing about one to two weeks beforehand. On treatment day, arrive with clean skin free from makeup or other products, and arrange for someone to drive you home.
Before treatment, we apply topical anaesthetic cream to ensure your comfort. During the procedure, the CO2 laser creates thousands of microscopic columns of treated tissue in a controlled pattern. You may feel warmth or a prickling sensation, though anaesthetic significantly reduces discomfort. Treatment typically takes thirty minutes to two hours depending on the area size and intensity required.
Immediately after, your skin will appear red and feel similar to a sunburn. We apply protective ointment and provide detailed aftercare instructions. Recovery involves significant downtime with redness, swelling, and peeling lasting one to two weeks, with full healing taking several weeks longer. Results develop gradually as collagen remodeling occurs over several months.
If you have persistent acne scars, sun damage, deep wrinkles, or textural concerns that other treatments haven’t adequately addressed, book a consultation at South Yarra Dermatology to discuss whether CO2 laser is right for you.
Most patients find CO2 laser treatment uncomfortable but manageable with proper numbing. We apply a topical anaesthetic cream before treatment to minimise discomfort, and many patients describe the sensation during treatment as a warm, prickling feeling or like small rubber bands snapping against the skin. The intensity of sensation can vary depending on the treatment depth and the areas being treated, with some zones being more sensitive than others.
After treatment, once the numbing wears off, your skin will feel similar to a moderate sunburn with heat, tightness, and tenderness. We’ll provide pain management recommendations and cooling strategies to keep you comfortable during the initial healing period.
CO2 laser requires significant downtime compared to gentler treatments, typically ranging from one to two weeks depending on treatment intensity. Immediately after treatment, your skin will be red, swollen, and oozing, requiring you to stay home and focus on healing. The first three to five days involve the most intensive aftercare, with your skin crusting and peeling as it sheds the treated layers.
Most people can return to work and social activities after seven to ten days once the worst of the peeling has resolved and redness has calmed enough to be covered with makeup if needed. However, pinkness can persist for several weeks to a few months, gradually fading over time. You’ll need to avoid sun exposure, exercise, and certain skincare products during the initial healing phase.
You’ll notice initial improvements in skin texture and tone once the peeling phase completes, usually around seven to fourteen days after treatment. However, the most significant results develop gradually over the following three to six months as your skin produces new collagen and continues remodeling. Many people see progressive improvement during this time, with skin appearing smoother, firmer, and more even with each passing month.
For concerns like deep scars or severe sun damage, multiple treatment sessions spaced several months apart may be recommended to achieve optimal results. Patience is important with CO2 laser treatment, as the healing and collagen-building process takes time but delivers long-lasting improvements.
Many people achieve their desired results with a single CO2 laser treatment, particularly for overall rejuvenation and moderate concerns. However, deeper scars, significant sun damage, or more advanced ageing may benefit from two or three treatments spaced four to six months apart to allow complete healing between sessions.
Some patients prefer a series of lighter treatments with less downtime rather than one aggressive session, though this approach may take longer to achieve final results. Your dermatologist will recommend a treatment plan based on your specific concerns, skin condition, and how much downtime you can accommodate. The goal is to balance effectiveness with safety and practical considerations for your lifestyle.
We typically recommend starting a prescription skincare regimen four to six weeks before treatment to prepare your skin and support better healing. This usually includes products containing retinoids or other active ingredients that help optimise skin health. You’ll need to avoid sun exposure and tanning for at least four weeks before treatment, as sunburnt or tanned skin increases complication risks.
Certain medications and supplements that thin the blood or affect healing should be stopped before treatment if medically safe, including aspirin, ibuprofen, vitamin E, and fish oil. If you have a history of cold sores, you’ll need antiviral medication before treatment to prevent an outbreak during healing. Your dermatologist will provide a complete preparation checklist during your consultation.
Aftercare is crucial for safe healing and optimal results. For the first few days, you’ll need to cleanse your skin gently with a mild cleanser several times daily and apply thick layers of prescribed ointment to keep the treated area moist and protected. You must avoid picking or peeling any crusts, as this can cause scarring or pigmentation problems.
Sun protection is absolutely essential, requiring you to stay indoors as much as possible initially and use broad-spectrum SPF 50+ sunscreen once your skin has healed enough to tolerate it. You’ll avoid makeup, active skincare ingredients, exercise, hot showers, and anything that might irritate your healing skin for at least one to two weeks. We’ll schedule follow-up appointments to monitor your healing and address any concerns that arise.
You cannot wear makeup during the initial healing phase while your skin is oozing, crusting, and peeling, which typically lasts five to seven days. Once your skin has re-epithelialised (formed a new outer layer) and the dermatologist confirms it’s safe, you can begin using gentle mineral makeup to cover residual redness.
Choose non-comedogenic, fragrance-free products and apply them carefully without rubbing or irritating the skin. Many people return to wearing makeup around day seven to ten, which allows them to resume normal activities more comfortably while their skin continues healing underneath. We’ll recommend specific products that are safe for post-laser skin and won’t interfere with your continued recovery.
Results from CO2 laser treatment can last several years, particularly improvements in skin texture, pore size, and collagen structure. However, the treatment doesn’t stop the natural aging process, and new sun damage or wrinkles will continue to develop over time depending on your genetics, lifestyle, and sun protection habits. Many people maintain their results for five to ten years before considering additional treatment.
The longevity of your results depends significantly on how well you protect your skin from sun exposure, as UV damage is the primary cause of premature aging and can reverse some of your improvements. A good skincare routine, sun protection, and healthy lifestyle habits will help preserve your results as long as possible.
CO2 laser is an ablative treatment, meaning it removes skin tissue, whereas non-ablative lasers like IPL or fractional erbium work beneath the skin surface without removing layers. This makes CO2 more aggressive with more dramatic results but also more downtime and higher risks.
Other fractional lasers like Fraxel create less injury and require less recovery time but may need multiple sessions to achieve results comparable to one CO2 treatment. The choice between different laser types depends on your concerns, how much downtime you can accommodate, your skin type, and your tolerance for risk versus desired outcomes. Your dermatologist will explain which laser technology best suits your specific situation and goals.
