CO2 Laser Treatment in Quebec: A Complete Patient Guide
Everything you need to know about fractional CO2 laser resurfacing, from what it treats to what recovery actually looks like.
12 min read · Updated 2026
Fractional CO2 laser resurfacing is one of the most effective treatments available for scarring, deep wrinkles, and overall skin texture concerns. It has been a gold standard in dermatology and medical esthetics for decades, and modern fractional technology has made it safer and more tolerable than ever. If you are considering CO2 laser in Quebec, this guide covers exactly what to expect at every stage, so you can make a confident, informed decision. At Reimagine Clinic, we tailor every CO2 protocol to the individual, because no two patients have the same skin story.
What Is CO2 Laser Resurfacing
CO2 (carbon dioxide) laser emits a 10,600 nm wavelength that has an extremely high affinity for water molecules in skin cells. When the beam contacts your skin, it vaporizes thin layers of damaged tissue with pinpoint precision. The term “fractional” means the laser beam is split into thousands of microscopic columns, treating a fraction of the skin while leaving healthy tissue intact between each column. That surrounding healthy tissue acts as a healing reservoir, dramatically speeding recovery compared to older, fully ablative CO2 resurfacing.
The controlled thermal injury triggers your body’s wound-healing cascade. New collagen and elastin fibers replace the vaporized tissue, and the fresh skin that emerges is smoother, firmer, and more evenly toned. This remodeling process continues for months after treatment, meaning results keep improving long after the initial healing period. Modern laser platforms allow practitioners to adjust depth, density, and energy precisely, making it possible to treat delicate areas like the eyelids and aggressive areas like deep acne scars in the same session with different settings.
At Reimagine Clinic’s laser rejuvenation program, we use the latest fractional CO2 technology that allows us to balance aggressive resurfacing with patient comfort and manageable downtime. The goal is always the best possible outcome with the most reasonable recovery for your lifestyle.
PDRN's original approved use chronic wound healing in damaged tissue operates under very different biological conditions than applying the compound to healthy skin for cosmetic improvement. Extrapolating wound-healing data to anti-aging claims is a significant scientific leap that has not been validated in large, well-controlled clinical trials.
What CO2 Laser Treats
The versatility of CO2 laser is one reason it remains so popular. Acne scars are one of the most common indications. Boxcar and rolling scars respond particularly well because the laser resurfaces the raised edges while stimulating collagen in the depressed centers, evening out the texture over multiple remodeling cycles. For patients with active breakouts, we typically recommend an anti-acne facial protocol first to calm inflammation before proceeding with laser.
Fine lines and wrinkles around the mouth, eyes, and forehead respond excellently. The thermal tightening effect combined with new collagen production creates a firming result that’s visible even after a single session. For patients dealing with sagging skin alongside textural concerns, CO2 laser often delivers improvement on both fronts simultaneously.
Hyperpigmentation and sun damage also benefit. By removing the outermost layers where pigment accumulates, CO2 laser reveals the clearer skin underneath. It is also used for skin lesion removal, including moles, age spots, and other benign growths. The precision of the laser beam makes it ideal for removing lesions while minimizing damage to surrounding tissue.
Can CO2 laser treat stretch marks?
Fractional CO2 can improve the texture and appearance of stretch marks, though complete removal is unrealistic. It works by stimulating collagen remodeling within the stretch mark itself. Combining CO2 with RF microneedling often produces better outcomes for stretch marks than either treatment alone.
Is CO2 laser effective for enlarged pores?
Yes. The thermal tightening effect shrinks pore diameter, and the resurfacing smooths the skin around pore openings. For mild pore concerns, less aggressive options like microdermabrasion or chemical peels may be sufficient.
Injectable PDRN products are not approved by the FDA in the United States or by Health Canada for cosmetic applications. This means there has been no independent regulatory verification of safety, efficacy, or manufacturing quality for aesthetic injectable use. Without regulatory approval, there is no guarantee of product sterility, consistent concentration, or purity all critical factors when a substance is being injected into your skin.
The CO2 Laser Procedure Step by Step
Preparation starts 2 to 4 weeks before your session. You will be asked to discontinue retinoids, exfoliating acids, and any photosensitizing medications. Patients prone to cold sores are typically prescribed antiviral medication as a precaution. If you have a HydraFacial or deep cleansing facial scheduled, it should be completed at least two weeks before the laser session so the skin has time to return to baseline.
On treatment day, the skin is thoroughly cleansed and a topical numbing cream is applied for 30 to 45 minutes. For deeper treatments, local anesthesia or nerve blocks may be used for additional comfort. Once the skin is numb, the practitioner passes the laser handpiece over the treatment area in a systematic pattern. You will hear a rapid clicking sound and may feel warmth or a prickling sensation, but the numbing keeps discomfort minimal.
Treatment time ranges from 15 minutes for a small area (around the mouth, for example) to 45 minutes for a full face. Immediately after, the skin appears red and swollen, similar to a significant sunburn. A soothing ointment or hydrating mask is applied, and you will receive detailed aftercare instructions. At Reimagine Clinic, every patient leaves with a clear recovery roadmap and direct access to our team for questions during healing.
PDRN is not without scientific interest the underlying biology of adenosine receptor activation and tissue repair is legitimate. However, the gap between promising preclinical data and proven clinical efficacy for aesthetic use remains wide. The current state of evidence does not support PDRN as a reliable, first-line treatment for skin rejuvenation. The studies are too small, too inconsistent, and too often conflicted to draw confident conclusions about how well it works, how long results last, or how it compares to established treatments.
Recovery Timeline and What to Expect
Days 1 to 3: This is the most intense phase. Expect significant redness, swelling, and oozing. The skin may feel tight and warm. Keep the area moist with the recommended ointment and avoid touching it with unwashed hands. Sleeping on an elevated pillow helps reduce facial swelling. Gentle cleansing with lukewarm water is typically started on day 2.
Days 4 to 7: The skin starts to form micro-crusts as the treated columns heal. Peeling begins, and the temptation to pick is real, but resist it. Picking can cause scarring and infection. The redness starts to settle from bright red to a pinkish hue. Most patients feel comfortable going out in public with mineral makeup by day 7 to 10.
Weeks 2 to 6: Redness continues to fade gradually. The new skin may feel dry and tight, so consistent moisturizing is essential. Avoid direct sun exposure and wear SPF 50+ daily without exception. LED light therapy sessions during this phase can help calm residual redness and support collagen production. A gentle classic facial at week 4 can also restore hydration and comfort. Collagen remodeling continues for 3 to 6 months, so the full result develops gradually. Patience during this phase is key.
When can I wear makeup?
Mineral makeup is usually safe by day 7 to 10. Avoid conventional makeup with fragrances or irritating ingredients until the skin is fully healed (typically 2 to 3 weeks). Your practitioner will confirm when it is safe based on your healing progress.
Can I exercise during recovery?
Avoid strenuous exercise for 7 to 10 days. Sweating can irritate healing skin and increase the risk of infection. Light walking is fine from day 2 onward. Gradually reintroduce workouts as redness subsides.
Combining CO2 With Other Treatments
CO2 laser works beautifully as part of a multi-modality treatment plan. For acne scars, combining CO2 with RF microneedling addresses both surface and deep dermal layers. The CO2 resurfaces the top, while radiofrequency microneedling remodels collagen from within. Clinical studies consistently show that combination protocols outperform single treatments for moderate to severe scarring.
Skin booster injections with hyaluronic acid can be administered between CO2 sessions to keep the skin deeply hydrated and plump, which supports faster healing and better collagen quality. Exosome therapy applied immediately post-laser is another powerful adjunct that delivers growth factors directly to the healing tissue, amplifying the regenerative response.
For patients whose primary concern is aging rather than scarring, pairing CO2 with neuromodulator injections and dermal fillers creates a comprehensive rejuvenation plan. The laser handles texture, tone, and tightening, while injectables restore lost volume and relax dynamic wrinkles. Sculptra is particularly complementary because it stimulates your own collagen production over time, reinforcing the remodeling that CO2 initiates.
- ☐1. Is it approved or cleared by a regulatory body (FDA, Health Canada)?
Regulatory approval means independent scientists have reviewed the safety and efficacy data and found it sufficient. Without this, you are relying on marketing claims alone. - ☐2. How large are the clinical studies?
A study with 15 participants does not carry the same weight as a trial with 200. Look for systematic reviews that pool data from multiple studies. - ☐3. Who funded the research?
Manufacturer-funded studies are more likely to report favorable results. Independent research is more reliable. - ☐4. How long were patients followed?
A treatment that shows improvement at 4 weeks but has not been tracked at 6 or 12 months tells you very little about durability. - ☐5. How does it compare to established treatments?
If a new treatment has not been directly compared to proven options in head-to-head trials, there is no basis for claiming it is equal or superior.
Results, Costs, and Next Steps
Most patients see noticeable improvement after a single CO2 session, with full results developing over 3 to 6 months as collagen remodeling completes. For mild to moderate concerns, one to two sessions may be sufficient. Severe scarring or deep wrinkles typically require two to three sessions spaced 8 to 12 weeks apart. Each session builds on the last, and the cumulative effect is substantial.
Results are long-lasting because the new collagen and skin tissue are genuinely regenerated, not temporarily improved. However, ongoing sun protection is essential to preserve your results. Sun damage is the fastest way to undo the benefits of laser treatment. Annual maintenance with lighter treatments like chemical peels, IPL sessions, or microneedling can extend and build on your CO2 results over time.
CO2 laser is an investment, and the cost reflects the technology, expertise, and results involved. Pricing depends on the treatment area, number of sessions, and complexity. At Reimagine Clinic, we offer flexible financing options to make multi-session protocols accessible. The best starting point is a free consultation where we assess your skin, discuss realistic expectations, and build a personalized plan.

Health Canada maintains strict standards for medical devices and injectable products used in aesthetic medicine. When evaluating any new treatment, check whether it has received Health Canada approval or clearance this is your strongest signal that independent experts have reviewed the evidence. All treatments offered at Reimagine Clinic meet or exceed these regulatory standards.

Frequently Asked Questions
Is CO2 laser painful?
With proper numbing, most patients describe it as tolerable. You may feel warmth, prickling, or mild stinging. The numbing cream applied beforehand handles most of the discomfort. Deeper treatments may use local anesthesia for additional comfort. Post-treatment, the skin feels like a sunburn for 1 to 2 days.
How many sessions will I need?
It depends on the concern. Mild sun damage and fine lines may improve significantly in one session. Moderate to severe acne scars usually require 2 to 3 sessions spaced 8 to 12 weeks apart. Your practitioner will outline a realistic plan during your free consultation.
Is CO2 laser safe for darker skin tones?
Fitzpatrick skin types I through IV are generally good candidates. Types V and VI carry a higher risk of post-inflammatory hyperpigmentation. For darker skin tones, settings are adjusted to lower densities, or alternative treatments like RF microneedling may be recommended as a safer option with less pigmentation risk.
