Short answer: they're very different things. Topical PDRN (salmon DNA) is a gentle cosmetic skincare ingredient that supports the look of hydrated, smooth skin. Anti-wrinkle injections and dermal fillers are clinical, prescription-based procedures performed by qualified practitioners. One is a serum you apply; the others are treatments you book. Here's how they compare. Browse topical PDRN skincare.
PDRN — polydeoxyribonucleotide — is a popular skincare ingredient derived from salmon DNA, used in serums and skin boosters to support the appearance of healthy, hydrated, even-looking skin. It's often more affordable than clinical procedures, which is part of why it's become a routine staple. Because it's a topical cosmetic, it works at the surface to support how skin looks and feels — it isn't a medicine and doesn't treat medical conditions.
Salmon DNA is structurally very similar to human DNA, which makes it gentle and biocompatible. It has been used in Korean skincare for over a decade and is now popular in Australia.
Topical PDRN salmon DNA skincare
What's in it
PDRN is made up of deoxyribonucleotides — the building blocks of DNA — in fragmented form, purified from salmon. Topical formulas typically also include water as a base, stabilisers and preservatives, and often supporting actives like hyaluronic acid or antioxidants.
What people value it for (cosmetically)
- Hydration: helps attract and hold moisture for a plump, dewy look.
- Smoother appearance: with consistent use, supports the look of smoother texture and softened fine lines.
- Comforting feel: a gentle ingredient that suits sensitive-feeling skin and helps calm the look of redness.
- Gentle & low downtime: as a topical cosmetic, it's non-invasive and easy to layer into a routine.
You'll find PDRN across our VITARAN and Curenex ranges, and in products like Jeunetique EXOsomes & PDRN 3% and the VITARAN B Niacinamide serum.
Anti-wrinkle injections
What they are: a prescription treatment using botulinum toxin type A, administered by qualified practitioners in a clinical setting.
- Muscle relaxation: temporarily relaxes specific muscles to soften the look of dynamic lines (e.g. frown lines, crow's feet).
- Fast visible change: results typically appear within days.
- Temporary: effects usually last around 3–6 months.
Dermal fillers
What they are: injectable gels (often hyaluronic acid, sometimes calcium hydroxylapatite or poly-L-lactic acid), placed by qualified practitioners.
- Volume & contour: add immediate volume to areas like cheeks, lips and under-eyes.
- Hydration: HA fillers hold moisture for a plump look.
- Tailored: different fillers suit different areas.
How they compare
These approaches do different jobs and aren't direct substitutes for one another:
- Topical PDRN salmon DNA is a gentle, everyday cosmetic that supports the look and feel of hydrated, smooth skin over time.
- Anti-wrinkle injections are a clinical treatment focused on softening dynamic lines — they don't hydrate or condition the skin's surface.
- Dermal fillers are a clinical treatment focused on adding volume and contour.
Many people use a topical PDRN serum as their daily skincare foundation, and separately decide — with a qualified practitioner — whether clinical treatments are right for them. If you'd like to start with the gentle, at-home option, that's where we can help.

Frequently asked questions
Is PDRN an alternative to anti-wrinkle injections?
Not exactly — they do different things. Topical PDRN is a cosmetic that supports the look of hydrated, smooth skin, while anti-wrinkle injections are a clinical treatment that relaxes specific muscles. Many people use skincare daily and consider clinical treatments separately with a practitioner.
Is PDRN skincare cheaper than injectables?
Generally yes — a topical PDRN serum is an everyday skincare product rather than a clinical procedure, so it's typically far more affordable.
Can I use PDRN serum alongside clinical treatments?
Many people use gentle topical skincare as part of their routine. If you've had a clinical treatment, follow your practitioner's aftercare advice and reintroduce products gently.

Softening the look of lines and wrinkles around the mouth
One of the areas people ask about most is the mouth — the fine vertical "lip lines" above the top lip, and the smile or nasolabial lines that run from the nose to the corners of the mouth. Because the skin here is thin, mobile and in constant use, lines around the mouth are often among the first to show.
Clinically, deeper static folds around the mouth are usually addressed with dermal fillers, while dynamic movement is sometimes softened with anti-wrinkle injections — both performed by a qualified practitioner. As an everyday cosmetic foundation, a topical PDRN salmon DNA serum supports the look of hydrated, plumper, smoother skin around the mouth, which can make fine lines appear softer over time. Applying it consistently — and gently microneedling at home to help it absorb — is the gentlest at-home approach to the appearance of wrinkles around the mouth.
A simple routine for this area: cleanse, apply a hydrating PDRN or exosome serum while skin is slightly damp, then seal with a gentle moisturiser and daily SPF — sun exposure is one of the biggest drivers of how lined the mouth area looks. Consistency, not intensity, is what makes the difference.
What helps with lines around the mouth?
For the everyday cosmetic approach, a hydrating topical PDRN or exosome serum supports the look of plumper, smoother skin around the mouth, and daily SPF helps limit further sun-related lining. Deeper folds are typically addressed clinically with fillers by a qualified practitioner.
Can skincare reduce wrinkles around the mouth?
Topical skincare can't remove wrinkles, but a gentle PDRN salmon DNA serum used consistently supports the appearance of hydrated, smoother skin, which can make fine lines around the mouth look softer over time. Results are cosmetic and cumulative.
