Rejuran vs CureNex vs VITARAN: Which Salmon DNA Skincare Is Right For You?

Updated April 2026 · about a 7 minute read

Rejuran, CureNex and VITARAN all wear the salmon DNA badge, but they are not the same thing.

If you have spent any time on skincare TikTok lately, you have probably seen the words “salmon DNA” pop up more than once. PDRN based skincare has gone from niche Korean clinic secret to full blown global beauty obsession, and with that surge in popularity comes a lot of options. Three names come up more than any others: Rejuran, CureNex and VITARAN.

So which one is right for you? Let us break it down honestly, conversationally, and without the marketing fluff.

Want the wider picture? Our PDRN serum showdown compares these alongside Medicube and Dr. Drawing too, with a full breakdown of PDRN concentrations and pricing.

First, what even is PDRN?

PDRN stands for polydeoxyribonucleotide. It is a fancy name for small DNA fragments extracted from salmon (yes, really, and no, your skin will not smell like sushi). These fragments are similar in structure to human DNA, which is why they have become such a talking point in the skincare world.

In cosmetic skincare you apply at home, PDRN is included as a cosmetic ingredient designed to support the appearance of hydrated, smoother, more radiant looking skin. It has become one of the buzziest ingredients in K beauty and is now making its way into routines all over Australia. New to it?

An important distinction: injectable versus cosmetic

Before we dive into the comparison, there is something important to know. Rejuran is an injectable treatment performed by qualified medical professionals, a prescription only procedure that falls under Australia’s TGA regulations for therapeutic goods. CureNex and VITARAN, on the other hand, are cosmetic skincare products you apply to the surface of your skin.

That means these are not really “apples to apples” comparisons. An injectable procedure and a serum you apply yourself work in very different ways and are regulated very differently. But because all three get lumped together in the “salmon DNA” conversation, we think it is worth explaining what each one actually is so you can make an informed choice.

Rejuran is a clinic procedure. CureNex and VITARAN are the salmon DNA cosmetics you can actually take home.

Rejuran: the injectable procedure

What it is: A prescription only injectable procedure administered by qualified medical professionals in Australia. It is delivered through micro injections into the skin during a clinical session.

Best for: People who are comfortable with injectable cosmetic procedures and want a clinic based treatment. It is not something you can do at home, and it requires booking with a licensed practitioner.

The catch: It is a medical procedure, so there is downtime, cost per session, and it must be done by a qualified practitioner. For people who want a daily use option they apply at home, this is not the right fit.

Note: we do not stock Rejuran, as it is a prescription injectable and a therapeutic good. You would need to book this through a registered clinic if it is something you are interested in.

VITARAN Skin Radiance Series: the all rounder you apply at home

What it is: A cosmetic skincare range from Korea, designed for daily use at home. The star of the show is the combination of PDRN with 5% encapsulated exosomes, NMN (a precursor to NAD+), and a blend of nourishing ingredients like Centella, Adenosine, Niacinamide and Azulene.

What makes it interesting: VITARAN uses capsule technology that keeps the active ingredients stable until you apply the product. The capsules burst as you massage the serum in, meaning you are getting the ingredients at their freshest with every use.

Best for: People who want a complete daily cosmetic skincare routine with a science forward formulation. If you love the idea of pairing PDRN with exosomes, NMN and other supporting actives in one product, VITARAN is hard to beat for use at home. Explore the VITARAN range →

Professional use? Yes, VITARAN is also used in salon and clinic settings alongside other treatments.

CureNex: the clinic favourite for targeted use

What it is: A PDRN based skincare range developed in Korea, with a strong reputation among professionals. CureNex focuses on high purity PDRN formulations designed for targeted use, particularly alongside professional treatments.

What makes it stand out: CureNex built its reputation in clinic settings first, which is why it has become one of the most trusted names for professionals looking for a reliable PDRN serum. The formulations are clean, focused, and designed to pair seamlessly with clinic and at home routines.

Best for: If you are already doing an at home treatment (or thinking about starting), CureNex is the serum we recommend. It is formulated to be used during and after your treatment sessions to help your skin feel hydrated, comfortable and look its best.

Our take: If you want a targeted product that is as happy in a salon as it is on your bathroom counter, CureNex is our top pick. Shop the CureNex range →

Side by side comparison

So which one should you pick?

Here is the honest answer: it depends on what you are looking for and how you like to approach your skincare.

Choose Rejuran if you are comfortable with injectable cosmetic procedures and want a clinic based treatment administered by a licensed practitioner. Just remember, you will need to book through a registered clinic, as it is a therapeutic good we do not sell.

Choose VITARAN if (and this is our top pick) you want a daily cosmetic skincare routine that brings together PDRN, exosomes, NMN and supporting actives all in one product. It is the product we would recommend for an easy, no fuss way to introduce advanced K beauty ingredients to your everyday routine.

Choose CureNex if you want a clean, targeted PDRN serum that works beautifully on its own or alongside a treatment. It is the product we would recommend for anyone wanting a clinic favourite serum they can use at home.

Is there an at home alternative to Rejuran? (PDRN without injections)

This is one of the most common questions we hear from Australians researching salmon DNA skincare: is there a Rejuran alternative you can use at home? The honest answer is that no cosmetic can replicate a prescription injectable, they are different categories and are regulated differently. But if your goal is simply to bring PDRN (salmon DNA) into your routine without injections, a PDRN serum you apply on its own, or press in with a gentle at home treatment, is the closest at home approach.

Most people searching for an at home alternative to Rejuran in Australia want the salmon DNA ingredient story without the downtime, cost per session or clinic visits of an injectable. A daily cosmetic like VITARAN (which pairs PDRN with exosomes and NMN), or a targeted serum like CureNex used alongside a derma stamp or treatment pen, lets you use PDRN consistently at home. If you are weighing what you can apply at home against in clinic procedures, our exosome treatment and therapy guide explains how the at home and clinic routes compare.

Keep expectations realistic: a serum you apply absorbs into the surface of the skin and supports the appearance of hydrated, smoother, more even skin over time. It is a cosmetic product, not a substitute for a medical procedure, and results are gradual and cumulative.
