The Complete Guide to Cosmetic Injections in Montreal
Fillers, neuromodulators, skin boosters, and more: a no-nonsense guide to every injectable option available in Montreal.
13 min read · Updated 2026
Cosmetic injections have become the most popular non-surgical aesthetic treatments worldwide, and Montreal is no exception. Whether you are curious about dermal fillers for restoring lost volume, neuromodulators for softening expression lines, or skin boosters for a deep hydration glow, this guide walks through every option, what each one does best, and how to make an informed choice at Reimagine Clinic.
Types of Cosmetic Injectables
The world of cosmetic injectables breaks down into a few distinct categories, each with a different mechanism and purpose. Understanding these categories is the first step toward choosing the right treatment for your goals.
Dermal fillers are gel-like substances injected beneath the skin to restore volume, smooth lines, and enhance facial contours. Most are made from hyaluronic acid (HA), a molecule that occurs naturally in your skin. Neuromodulators (like Botox, Dysport, and Nuceiva) temporarily relax the muscles that cause dynamic wrinkles, such as forehead lines, frown lines, and crow’s feet. Skin boosters are micro-injections of hyaluronic acid designed to hydrate and improve skin quality rather than add volume. Biostimulators like Sculptra stimulate your body to produce its own collagen over time.
Each category serves a different purpose, and the best results often come from combining two or more strategically. A patient dealing with wrinkles plus volume loss will benefit from a plan that includes both neuromodulators and fillers, for example. Your injector should never suggest a single product for every concern.
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.
Dermal Fillers: Restoring Volume and Contour
Dermal fillers are the workhorse of facial rejuvenation. They can plump deflated cheeks, smooth nasolabial folds, sharpen the jawline, correct under-eye hollows, and enhance the chin. Lip filler remains one of the most requested treatments, used for both subtle volume enhancement and defining the lip border.
HA fillers come in different densities and viscosities. Thicker, more cohesive gels are used for structural support (cheeks, jawline, chin), while softer, more fluid formulations work best for delicate areas (lips, under-eyes, fine lines). The choice of product matters enormously, and an experienced injector selects the right filler for each specific area and concern.
Results are immediate and typically last 6 to 18 months depending on the area, product, and your metabolism. The under-eye area tends to hold filler longer because there is less movement, while lips metabolize filler faster. Touch-up sessions every 6 to 12 months maintain the result without starting from scratch. For patients with significant volume loss, Sculptra is an excellent alternative that stimulates collagen production gradually over several months, producing a more natural-looking fullness.
Can fillers be dissolved if I do not like the result?
Yes. Hyaluronic acid fillers can be dissolved with an enzyme called hyaluronidase, which breaks down the filler within hours. This safety net is one of the reasons HA fillers are the most popular choice worldwide. Non-HA fillers like Sculptra cannot be dissolved.
What about under-eye filler for dark circles?
Dark circles caused by volume loss (a hollow, shadowed appearance) often respond well to filler. However, dark circles caused by pigmentation or thin skin require different approaches. A proper assessment determines the cause before recommending treatment.
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.
Neuromodulators: Softening Expression Lines
Neuromodulators work by temporarily blocking the nerve signals that tell muscles to contract. When the muscles responsible for frown lines, forehead creases, and crow’s feet relax, the overlying skin smooths out. The effect is not instant; it takes 3 to 7 days to begin and reaches full effect at 2 weeks.
Modern neuromodulator treatment has moved far beyond simply “freezing” the forehead. Skilled injectors use micro-doses placed strategically to achieve a natural, expressive result. You should still be able to raise your eyebrows, smile fully, and show emotion. The goal is to soften lines, not erase movement. Popular brands in Canada include Botox, Dysport, and Nuceiva, all containing botulinum toxin type A.
Results last 3 to 4 months on average, and regular treatments can actually train the muscles to relax over time, meaning some patients eventually need less product or less frequent visits. Beyond wrinkle reduction, neuromodulators are also used for jawline slimming (masseter reduction), excessive sweating (hyperhidrosis), and gummy smile correction. Combined with fillers, they form the foundation of most non-surgical anti-aging plans.
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.
Skin Boosters, Biostimulators, and Newer Options
Skin boosters are a category of injectable that prioritizes skin quality over volume. Tiny droplets of hyaluronic acid are injected across the face, neck, hands, or decolletage in a grid pattern. Rather than plumping or filling, they hydrate the skin from within, improving texture, elasticity, and radiance. Patients often describe the effect as a “glow from the inside.”
Sculptra is a biostimulator containing poly-L-lactic acid. Unlike HA fillers that provide immediate volume, Sculptra works gradually by triggering your body’s own collagen production. Results develop over 2 to 3 months and can last up to 2 years. It is particularly effective for patients with widespread volume loss and skin laxity who want a natural, progressive improvement rather than an immediate transformation.
Exosome therapy and PRP (platelet-rich plasma) are newer regenerative options. Exosomes deliver growth factors and signaling molecules to aging cells, while PRP uses your own blood’s healing properties. These treatments focus on cellular-level rejuvenation and pair exceptionally well with microneedling or RF microneedling to amplify results. For those interested in the science, our article on facial boosters explores these options in detail.
How do skin boosters differ from fillers?
Fillers add volume to specific areas. Skin boosters spread micro-droplets across a wide area to improve overall hydration and quality. Think of fillers as architecture (structural) and skin boosters as interior design (surface refinement). Many patients benefit from both.
Is PRP or exosome therapy right for me?
These regenerative treatments work best for patients seeking overall skin quality improvement, particularly those with early laxity or dull, tired-looking skin. They are also popular for hair loss treatment when combined with microneedling of the scalp.
Choosing the Right Injectable for Your Goals
The most common mistake patients make is fixating on a specific product before understanding their actual concern. “I want Botox” or “I want lip filler” are starting points, not treatment plans. A thorough consultation should analyze your facial anatomy, identify the root cause of what bothers you, and recommend the right category (or combination) of injectables accordingly.
For example, deep lines around the mouth might look like they need filler, but if those lines are caused by repeated muscle contraction, neuromodulators address the cause while filler addresses the symptom. Treating both produces a much better and longer-lasting result than either alone. Similarly, a patient who wants “more volume” in the cheeks may actually benefit more from Sculptra’s gradual collagen stimulation than from a large bolus of HA filler.
Budget is a practical consideration. Neuromodulators require repeat treatments every 3 to 4 months. Fillers last 6 to 18 months. Sculptra lasts up to 2 years. Skin boosters need 2 to 3 initial sessions plus maintenance every 6 months. At Reimagine Clinic, we help patients plan a realistic treatment timeline that balances their goals with their budget. Financing options are available for comprehensive plans.
- ☐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.
Safety, Aftercare, and What to Watch For
Cosmetic injections are safe when performed by trained professionals using genuine, regulated products. In Quebec, the medical esthetic industry is well-regulated, but patients should still do their due diligence. Always ask about your injector’s qualifications, the specific products being used, and what protocols are in place for managing complications.
Common side effects include temporary redness, swelling, bruising, and tenderness at the injection sites. These typically resolve within a few days. More serious but rare complications include infection, vascular occlusion (filler blocking a blood vessel), and asymmetry. An experienced injector minimizes these risks through thorough knowledge of facial anatomy, proper technique, and having emergency protocols readily available.
Aftercare is straightforward: avoid touching the treated area for 4 to 6 hours, skip strenuous exercise for 24 hours, and avoid alcohol on the day of treatment. For fillers, avoid extreme heat (saunas, hot yoga) for 48 hours. For neuromodulators, stay upright for 4 hours and avoid rubbing the treated area. Follow-up appointments at 2 weeks allow your injector to assess results and make any adjustments. At Reimagine Clinic, every injection patient receives detailed aftercare guidance and access to our team for any post-treatment concerns.

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
Do cosmetic injections hurt?
Most patients describe mild discomfort rather than pain. Fillers often contain lidocaine (numbing agent) mixed in. Neuromodulators use very fine needles, and the injections take seconds. Topical numbing can be applied for sensitive patients. The discomfort is brief and manageable for the vast majority of people.
At what age should I start getting injectables?
There is no fixed age. Prevention-focused patients in their mid-20s may benefit from small doses of neuromodulators to prevent lines from forming. Patients in their 30s and beyond often combine neuromodulators with fillers. The right time depends on your concerns and goals, not a number on a calendar.
Can I combine injectables with laser or facial treatments?
Absolutely. In fact, the best aesthetic outcomes often come from a multi-modality plan. Laser treatments address texture and tone, facials maintain skin health, and injectables handle volume and movement. Timing matters, so your practitioner will schedule treatments in the right sequence.
