Collagen Induction Therapy: The Complete Guide for Montreal Patients
Everything you need to know about collagen induction therapy, from how microneedling triggers real skin renewal to choosing the right clinic in Montreal for lasting results.
14 min read
If you have been researching ways to improve your skin texture, reduce fine lines, or fade acne scars, you have probably come across the term “collagen induction therapy.” It sounds clinical, but the concept is surprisingly straightforward: create controlled micro-injuries in the skin so your body responds by producing fresh collagen and elastin.
The result? Firmer, smoother, more even-toned skin that looks renewed from within. At Reimagine Clinic in Montreal, we have helped hundreds of patients experience this transformation firsthand. This guide walks you through the science, the process, and everything else you should know before booking your first session.

What Is Collagen Induction Therapy?
Collagen induction therapy (CIT) is a professional skin treatment that uses fine, sterile needles to create thousands of tiny punctures in the top layers of your skin. These micro-channels are barely visible to the naked eye, but they are enough to trigger your body’s natural wound-healing cascade.
Within hours of treatment, your skin begins producing new collagen, the structural protein that keeps skin firm and smooth. Over the following weeks and months, this fresh collagen remodels the treated area, improving texture, tone, and overall quality.
You may also hear CIT referred to as microneedling, percutaneous collagen induction, or dermal needling. While there are subtle differences in technique and device, the underlying principle is the same across all of them.
Unlike ablative procedures such as laser treatments that remove layers of skin, collagen induction therapy works with your skin rather than against it. The micro-injuries are small enough that the epidermis remains largely intact, which means faster healing and less downtime.
CIT is one of the few treatments that improves skin quality at the structural level. That is why results continue to improve for months after each session.
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.
How Collagen Induction Therapy Works at the Cellular Level
Understanding the biology behind CIT helps explain why this treatment produces such consistent results. When the microneedling device creates those tiny channels in your skin, it sets off a three-phase healing response.
The first phase is inflammation. Your body recognizes the micro-injuries and sends growth factors, platelets, and white blood cells to the area. This begins within minutes and lasts roughly 24 to 48 hours. You will notice redness and mild swelling during this window.
The second phase is proliferation. Over the next one to two weeks, fibroblasts migrate to the treated area and begin producing new collagen (primarily type III). This new tissue fills in the micro-channels and starts rebuilding the dermal matrix.
The third phase is remodeling. Over the following months, the initial type III collagen gradually converts to stronger type I collagen. This is the same collagen that gives youthful skin its firmness. The remodeling phase can continue for up to a year after treatment, which is why patients often see progressive improvement.
This three-phase process is what separates CIT from surface-level treatments. While a classic facial or even a chemical peel can refresh the top layer of skin, collagen induction therapy rebuilds from deeper within the dermis.
What role do growth factors play?
Growth factors are signaling proteins released during the inflammation phase. They direct fibroblasts to the treatment area and stimulate collagen synthesis. Some advanced protocols combine microneedling with topical growth factor serums or exosome treatments to amplify this response, delivering active ingredients directly through the micro-channels while they remain open.
Why does depth matter?
Needle depth determines which layer of skin receives the micro-injuries. Shallow depths (0.25 to 0.5mm) are best for product absorption and mild texture improvement. Medium depths (1.0 to 1.5mm) target fine lines, enlarged pores, and superficial scars. Deeper settings (2.0 to 2.5mm) address deeper scars and wrinkles. A skilled practitioner adjusts depth by facial zone for optimal results.
How does CIT compare to RF microneedling?
RF microneedling adds radiofrequency energy to the standard microneedling process. The needles deliver heat energy into the dermis, which creates additional collagen stimulation and can tighten skin more effectively. RF microneedling is often preferred for sagging skin or deeper wrinkles, while standard CIT excels at texture, tone, and scar revision.
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.
Who Benefits Most from Collagen Induction Therapy
One of the reasons CIT has become so popular is its versatility. Unlike treatments designed for a single concern, collagen induction therapy addresses multiple skin issues simultaneously because it works at the foundational level of skin health.
Patients with acne scars are among the most common candidates. The new collagen produced during healing fills in depressed scars from the bottom up, gradually leveling the skin surface. Rolling and boxcar scars respond particularly well to a series of treatments.
Those dealing with early signs of aging also see excellent results. Fine lines around the eyes, mouth, and forehead soften as the dermis thickens with fresh collagen. Many patients choose CIT as a preventive strategy in their late 20s and 30s before deeper wrinkles develop.
People struggling with hyperpigmentation or sun damage find that CIT helps normalize melanin distribution as the skin renews itself. The treatment is safe for darker skin tones, which is a significant advantage over some laser and light-based alternatives.
Patients with enlarged pores, rough texture, or dull complexion also respond well. By stimulating cell turnover and collagen production, CIT essentially encourages your skin to behave like younger, healthier skin.
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.
What to Expect During Your CIT Session
Knowing what happens during a collagen induction therapy appointment helps you feel prepared and relaxed. Here is a step-by-step walkthrough of a typical session at our Montreal clinic.
Your appointment begins with a thorough skin analysis. We examine your skin under specialized lighting to assess texture, pore size, scarring depth, and any active concerns. This analysis helps us customize your treatment plan, including needle depth, speed settings, and whether to combine CIT with complementary products.
Next, we apply a medical-grade topical anesthetic to the treatment area. This numbing cream sits on your skin for about 20 to 30 minutes. Most patients describe the sensation during treatment as a mild vibrating pressure rather than pain.
Once the area is numb, we begin the microneedling pass. The device moves systematically across each zone of your face (or body), with your practitioner adjusting depth and speed based on the area. The forehead and cheeks can typically tolerate deeper settings, while delicate areas around the eyes require a lighter touch.
After the needling pass, we apply a calming serum or hyaluronic acid mask to soothe the skin and take advantage of the enhanced absorption through the open micro-channels. The entire process from start to finish usually takes about 60 to 90 minutes.
Does it hurt?
With proper numbing, most patients rate discomfort at 2 to 3 out of 10. The forehead and nose bridge tend to be slightly more sensitive, while cheeks and jawline are very tolerable. Some patients even find the vibration relaxing. If you have concerns about sensitivity, let your practitioner know and they can adjust the protocol accordingly.
Can CIT be combined with other treatments?
Absolutely. Many patients pair collagen induction therapy with facial boosters or skin booster injections for amplified hydration. Others combine it with LED light therapy post-treatment to reduce redness and accelerate healing. Your practitioner will recommend the best combination based on your skin goals.
How many sessions do I need?
Most patients see noticeable improvement after 3 to 4 sessions spaced 4 to 6 weeks apart. For deeper acne scars, 6 or more sessions may be recommended. Maintenance sessions every 3 to 6 months help sustain collagen levels as you age. During your free consultation, we will map out a personalized treatment timeline.
Recovery, Aftercare, and Maximizing Your Results
Recovery from collagen induction therapy is relatively quick compared to more aggressive skin treatments, but following proper aftercare makes a real difference in your results.
For the first 24 hours, your skin will look and feel sunburned. Redness, warmth, and mild swelling are completely normal and indicate that the healing process has begun. Most patients feel comfortable going out in public by day two or three, with any residual pinkness easily covered by mineral makeup.
During the first 48 hours, avoid active skincare ingredients like retinol, vitamin C serums, AHAs, and BHAs. Stick to a gentle cleanser, a hydrating serum, and a broad-spectrum SPF 30 or higher. Your skin is more vulnerable to sun damage while it heals, so sun protection is non-negotiable for at least two weeks following treatment.
Between sessions, maintaining a consistent skincare routine helps support the collagen-building process. A good HydraFacial or deep cleansing facial between CIT sessions can keep your skin clear and prepped for the next treatment.
- ☐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.
Choosing the Right Clinic for CIT in Montreal
Collagen induction therapy is only as effective as the practitioner performing it. The device, the technique, the needle depth protocol, and the post-treatment care all influence your outcome. Here is what to look for when choosing a clinic.
First, ask about the devices they use. Professional-grade microneedling pens with adjustable depth settings produce far better results than dermal rollers or basic stamp devices. At Reimagine Clinic, we use advanced motorized devices that allow precise control over needle depth, speed, and pattern.
Second, look for practitioners with proper training. In Quebec, esthetician training varies widely. Make sure your provider has completed specialized microneedling training and has experience treating your specific concern. A provider who treats dozens of patients per month will have a much better eye for customizing protocols than someone who does it occasionally.
Third, review their before-and-after gallery. Consistent, well-documented treatment results across different skin types and concerns tell you a lot about a clinic’s skill level. Be wary of clinics that only show their best single case.
Finally, consider the overall experience. A good clinic will offer a thorough consultation, explain realistic expectations, discuss financing options if needed, and provide clear aftercare instructions. The goal is to feel informed and confident before your first session.
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 collagen induction therapy safe for sensitive skin?
Yes, CIT is generally safe for sensitive skin when performed by an experienced practitioner. We adjust needle depth, speed, and the number of passes based on your skin’s tolerance. Patients with rosacea or reactive skin should discuss their concerns during the consultation so we can tailor the protocol appropriately.
How long do collagen induction therapy results last?
The collagen produced during CIT is your own natural collagen, so it does not dissolve or disappear like injectable fillers. However, your skin continues to age, so maintenance sessions every 4 to 6 months help sustain the improvements. Most patients find that a consistent maintenance schedule keeps their skin looking significantly better than their pre-treatment baseline for years.
Can I do microneedling at home instead?
Home dermal rollers operate at much shallower depths (0.1 to 0.25mm) and cannot achieve the collagen induction that professional devices deliver at 1.0 to 2.5mm. Home devices can help with product absorption, but they will not produce meaningful structural changes in the dermis. For real scar revision, wrinkle reduction, or skin tightening, professional CIT is necessary.
What is the difference between microneedling and collagen induction therapy?
They refer to the same fundamental treatment. “Collagen induction therapy” is the clinical term that emphasizes the biological outcome, while “microneedling” describes the technique itself. At Reimagine Clinic, we use both terms interchangeably.
