Rejuran in Canada: Not Licensed. What That Means, and the Legal PDRN Routes

Rejuran in Canada: not licensed, and nobody selling it will tell you that

The short version, before anything else. Rejuran is not licensed by Health Canada. Neither is Juvelook, Lenisna or Chaeum. Any clinic injecting them in Canada is injecting an unauthorized product. You can verify every word of that yourself in Health Canada’s public device database in about two minutes, and this article shows you how. It also explains what PDRN actually does, which PDRN treatments are legal in Toronto today, and where the serums fit. We offer some of those legal options, so read this knowing that, but every claim here is checkable and we would rather you check.

Rejuran is the most asked-about treatment we do not offer, and the reason we do not offer it is the entire point of this article. Most of what you will find about Rejuran in Toronto skips the licensing question, usually because it is written by someone selling it.

What Rejuran actually is

Rejuran is a Korean injectable made by PharmaResearch, built on PDRN: polydeoxyribonucleotide, purified fragments of DNA sourced from salmon. That is where the “salmon sperm facial” and “salmon DNA facial” nicknames come from. The idea is that these DNA fragments act as a repair signal in skin, supporting fibroblast activity and recovery rather than filling or freezing anything.

In Korea it is one of the most popular aesthetic treatments in the country, it is a fixture in Singapore, and it has spread through most of Asia. That popularity is real, and it is why the search demand arrived in Toronto years before the product legally could.

The Rejuran line, decoded

People ask about the versions by name, so here is the map. Rejuran Healer is the original, for overall skin quality, texture and elasticity. Rejuran S is a thicker formulation aimed at depressed acne scars. Rejuran I is the thinnest, made for the under-eye area. Rejuran HB blends PDRN with hyaluronic acid for hydration on top of repair. None of the four holds a Canadian licence. The differences matter in Seoul; in Toronto the licensing status flattens them into the same answer.

PDRN and polynucleotides are not quite the same word

You will see “polynucleotides” or “PN” used interchangeably with PDRN, and they are cousins rather than twins. PDRN refers to DNA fragments in a specific, lower molecular-weight range. Polynucleotide products use longer chains, which behave more like a supportive gel scaffold in the skin. Rejuran is PDRN. Several European injectables are PN. The distinction matters when you read studies, because results from one class get casually borrowed to sell the other. Our licensing point stands for the category: check MDALL for whichever brand name you are offered, and do not accept the study for one molecule as proof for a different one.

How to check the licence yourself

Do not take our word for any of this. Health Canada runs a public database of every licensed medical device in the country, called MDALL, and a search takes two minutes.

Search it for Rejuran. Nothing. Search Juvelook, Lenisna, Chaeum. Nothing, nothing, nothing. Zero licences between the four as of our last check in August 2026. Then compare: search any product a legitimate Toronto clinic advertises and the licence appears in seconds. We publish ours. The Préime DermaFacial arriving at our clinic is licence 113700, and you are welcome to look it up before you ever walk in.

An unauthorized product is not a technicality. It means Health Canada has never evaluated that specific product for safety, quality or manufacturing standards. It means no Canadian recall system is watching it. It means the vial reached the clinic through a channel that was not supposed to exist, which is exactly the environment counterfeits love, and counterfeit Korean injectables are a documented problem across Asia already. And Health Canada has seized unauthorized injectables from an Ontario spa, so enforcement here is not hypothetical either.

Rejuran in Toronto: what is actually being advertised

Search “Rejuran Toronto” and you will find clinics offering it, priced per session, photographed and hashtagged as if the licensing question did not exist. A few things are worth understanding about that market.

The product being injected got here informally. Nobody is importing an unlicensed injectable through the front door, because the front door checks licences. That means the clinic either bought from a grey importer or carried it in personally, and in both cases the cold chain, storage and authenticity are exactly as trustworthy as the person who arranged it.

The injectors offering it are not all villains. Some are skilled people who believe in the product and are responding to patients who keep asking. But you are the one wearing the outcome. If an authorized product injures you, there is a manufacturer, a licence holder and a regulator in the chain of responsibility. With an unauthorized one, that chain starts and ends at the clinic that chose to use it.

So if you are considering it anyway, ask one question: “Can you show me the Health Canada licence for this product?” There are only three possible answers. A licence, which for Rejuran cannot be produced, because none exists. A claim that it does not need one, which is wrong for an injectable. Or a change of subject, which is the most common answer and tells you how that clinic handles inconvenient facts generally.

Is Rejuran even good? The honest read

Popular is not the same as proven, so here is the fair version.

PDRN has a real research history. It has been used in wound-care medicine in Italy for decades, and there is published work on its role in tissue repair, including diabetic wound healing. On Rejuran specifically, there are Korean studies reporting improvements in skin texture, elasticity and fine lines, plus a large base of clinical experience across Asia. Most of the aesthetic studies are small and not blinded, which is the norm in this industry rather than a special mark against Rejuran. Patient satisfaction in markets where it is legal is genuinely high.

So our position is not “Rejuran is snake oil.” Our position is that it is a plausible, interesting product that has not passed the Canadian evaluation every product in our clinic has passed, and we do not inject things on vibes. When it gets licensed here, we will assess it seriously and probably carry it, because the demand is obvious. Until then, no.

What a Rejuran course looks like where it is legal

Worth knowing so you can compare honestly with the legal options below. In Korea and Singapore the standard protocol is a course, usually four sessions spaced two to four weeks apart, with maintenance every six months or so. Results build gradually across the course rather than appearing after one session. Sessions involve many small superficial injections, so expect pinpoint bruising and bumps for a day or two. Keep that “course, not miracle” shape in mind, because the legal PDRN routes below work on the same logic.

Flying to Korea or Singapore for it

Some Toronto patients solve the licensing problem with a plane ticket, and in those countries the product is legal and the clinics doing it at volume are genuinely experienced. If that is your plan, three practical notes. Book a clinic that treats internationals routinely and gives written aftercare in English. Leave at least a few days before flying home, because you want the injection sites settled and any reaction identified while you are still in the same city as your injector. And do not bring vials home for a Toronto clinic to inject: importing an unauthorized injectable for use here just recreates the entire problem, with you as the importer.

What PDRN does, in one minute

PDRN is a chain of DNA fragments cut to a size skin can use as a signal. The proposed mechanism runs through adenosine receptors on your cells: the fragments nudge fibroblasts toward repair mode, which over weeks reads as better texture, a stronger barrier, and skin that recovers faster and looks healthier. It is a regeneration ingredient, not a plumping one. Nobody should promise you filler results from it, in any format.

That mechanism is also why PDRN keeps appearing in serums, boosters and post-procedure care rather than staying an injectable. Which brings us to the part of this that is actually available in Canada.

PDRN serums: what works and what is marketing

You can buy PDRN skincare in Canada legally, because topical cosmetics sit in a different regulatory category from injectables. The catch is physics. PDRN is a large molecule, and large molecules do not wander through an intact skin barrier on their own. Rubbed on at home, a PDRN serum is a decent hydrator carrying a fashionable ingredient. Useful, not transformative, and the price should reflect that.

Three things separate a serious product from a label play. A stated concentration. If the label says “PDRN complex” with no percentage, the percentage is the answer you were not supposed to ask about. Meaningful products state numbers, and for reference the professional serum we use carries PDRN at a declared 0.1 percent. Sensible partners. PDRN pairs logically with niacinamide, hyaluronic acid and panthenol, which support the same repair-and-hydrate goal. A delivery plan. This is the one that decides the result, because getting PDRN past the barrier is the whole game, and no jar does that on its own.

The legal ways to get what Rejuran promises, in Toronto, today

Microneedling with PDRN. The closest legal cousin to the Rejuran experience. Controlled micro-channels are created across the skin and PDRN is delivered into them, reaching depths a topical never will. It runs as a course, typically three to four sessions about four weeks apart, with a day or two of redness after each. Texture, post-acne marks and overall skin quality are its lane. Full details are on our microneedling PDRN page, and the same page now carries our comparison of PDRN against exosomes and PRP if you are weighing the add-ons.

The Préime DermaFacial with UltraB delivery. The no-needle route. The Préime is a five-technology facial platform, new to Canada under licence 113700, and its ultrasound handpiece exists specifically to push actives past the barrier. The rejuvenating serum it drives in carries PDRN at 0.1 percent with niacinamide 2 percent and adenosine 0.04 percent. Ultrasound delivery is not injection depth, and we will keep saying that plainly, but it is a real delivery method, it is legal, it needs no downtime, and it is the option we point most Rejuran-curious people to first.

A licensed injectable skin booster. If what you want is specifically an injectable that improves skin quality rather than shape, that category exists legally in Canada. Teosyal Redensity 1 is Health Canada approved and it is what we use for exactly the “better skin, not bigger anything” request. It is not PDRN, it is a patented mix of hyaluronic acid with amino acids and antioxidants, but it is the licensed way to get an injected skin-quality result in this country today. Current pricing is on our price list.

Waiting. A legitimate answer we will defend. If it is Rejuran specifically you want, the right move is waiting for a licence, not sourcing it grey. When that day comes this page will say so, loudly.

Rejuran vs the legal options, side by side

Questions people actually ask

Is Rejuran approved by Health Canada?

No. As of August 2026 there is no Health Canada licence for Rejuran in any of its versions, and none for Juvelook, Lenisna or Chaeum either. You can verify this in Health Canada’s public MDALL database in about two minutes.

Can I get Rejuran in Toronto?

Some clinics offer it, but any Rejuran injected in Canada today is an unauthorized product that entered outside the approved channel. Ask the clinic to show you the Health Canada licence and watch what happens.

Is the salmon sperm facial the same thing as Rejuran?

“Salmon sperm facial” and “salmon DNA facial” are nicknames for PDRN treatments generally. Rejuran is one branded injectable version. Topical and device-delivered PDRN treatments exist legally in Canada; the injectable brand does not.

What is PDRN?

Polydeoxyribonucleotide: purified salmon DNA fragments used as a skin-repair signal. It supports fibroblast activity, which shows up over weeks as better texture, a stronger barrier and healthier-looking skin.

What is the difference between PDRN and polynucleotides?

Same family, different chain length. PDRN is the shorter-fragment form used as a repair signal. Polynucleotide (PN) products use longer chains that act more like a supportive scaffold. Studies on one are routinely used to sell the other, and they should not be.

Do PDRN serums actually work?

As hydrating skincare, yes. For deeper change the barrier is the obstacle, because PDRN is a large molecule. Delivery methods, microneedling channels or ultrasound, are what turn the ingredient into a result.

What should I look for in a PDRN serum?

A declared percentage rather than a vague complex, partners like niacinamide and hyaluronic acid, and a delivery plan. As a benchmark, the professional serum we use states PDRN at 0.1 percent.

Is PDRN safe? What about a fish allergy?

Topically and via delivery treatments it is well tolerated, and PDRN has decades of use in wound-care medicine. It is highly purified, but it is salmon-derived, so if you have a significant fish allergy, tell us at consultation and we will plan around it rather than guess.

Does PDRN help with hair?

It is being used and studied for scalp and hair-density work, and it is one of the more interesting corners of that field. We are watching it closely and will publish separately when we have something worth saying.

How much does Rejuran cost?

In Canada the honest answer is that no legal price exists, because no legal product exists. The legal PDRN routes and Redensity 1 are all on our price list, published like everything else we charge.

Can I buy Rejuran abroad and bring it to a Toronto clinic?

No. Importing an unauthorized injectable for use here recreates the entire problem with your name on the importation. If you want Rejuran, have it done where it is legal, by a clinic that does it daily.

When will Rejuran come to Canada?

Unknown. Licensing requires the manufacturer to apply and pass Health Canada evaluation, and no public approval exists. When it happens, this page will say so.

Rejuran vs Redensity 1, which should I pick?

In Canada the choice makes itself: one is unlicensed, one is Health Canada approved. On goals, both target skin quality rather than volume. If you want PDRN specifically, the legal routes are microneedling delivery or ultrasound delivery.

Why do you care so much about licences?

Because the licence is the entire difference between medicine and merchandise. Every device and injectable in our clinic can show its paperwork, and we think you should ask everyone for it, including us.

Profhilo is the skin booster people often compare Rejuran to, and unlike Rejuran it is approved in Canada.
