Polynucleotides vs Dermal Fillers: Understanding the Difference

One of the most common questions we hear in consultations at REGEN Clinic is a variation on: "I've heard about polynucleotides — how is it different from filler?" It is a good question, and the answer matters for how you think about what your skin actually needs.

The short version: fillers add volume. Polynucleotides regenerate tissue. These are different things, designed for different purposes, and understanding the distinction helps you make a more informed decision about which is right for your skin.

What Dermal Fillers Do

Dermal fillers — the most common of which are hyaluronic acid-based — work by adding physical volume to specific areas of the face. They are injected into targeted zones to restore volume that has been lost with age, soften deeper folds, or reshape features.

Fillers are effective for what they do. Volume replacement is a legitimate clinical goal for many clients. Well-placed, appropriately chosen filler in the right hands produces natural-looking results that can meaningfully refresh the face.

The key word in all of that is "replace." Fillers address the consequence of ageing — the volume that has been lost — rather than the underlying biology that caused it. They do not stimulate the tissue around them. They do not improve skin quality. And when they dissolve over the course of twelve to eighteen months, the structure they provided dissolves with them, returning the face broadly to where it was.

At REGEN, fillers are positioned as supportive within the Generate pillar — useful and appropriate for certain clients and certain concerns, but not the primary focus of a regenerative skin health approach.

What Polynucleotides Do

Polynucleotides (often abbreviated PDRN or PN) are fragments of DNA derived from salmon or trout sperm cells — highly purified and biocompatible with human tissue. Rather than adding volume or structure, they work at the cellular level: binding to receptors that stimulate tissue repair, promote new collagen formation, improve local circulation, and support the regeneration of damaged or ageing skin.

This is a fundamentally different mechanism. Polynucleotides do not replace what has been lost. They encourage the tissue itself to regenerate — producing genuine, biologically driven improvement in skin quality, elasticity, and hydration that is created by the skin's own cells rather than by an injected substance.

The results of polynucleotide treatment are more gradual than filler. There is no immediate visual change on the day of treatment. The improvement unfolds over four to eight weeks as the biological processes triggered by the treatment produce their effects. Clients describe the outcome as their skin looking better — healthier, more luminous, firmer — rather than looking different. This is consistent with how regenerative treatments work: the change is real, but it looks like the best version of you rather than an intervention.

Who Each Treatment Is For

These are not competing options — they address different concerns and work best for different clinical profiles.

Polynucleotides are particularly effective for clients who want to improve overall skin quality, address skin laxity and fine texture, treat the under-eye area (where filler carries more risk in inexperienced hands), or take a regenerative-first approach that supports the skin's own biology over time. They are also excellent for clients who have previously had filler and are looking to move toward a more natural, biologically led approach.

Fillers remain the most appropriate option for clients with specific volume concerns — significant nasolabial folds, deflated cheeks, lip enhancement, or structural changes to the jawline or chin — where tissue regeneration alone cannot address the degree of volume change present.

For many clients, the most considered approach combines both at different stages of a treatment plan. Polynucleotides first to improve tissue quality and skin health; filler later if volume remains a concern once the skin's own regenerative capacity has been supported.

Polynucleotides at REGEN: Pricing

A course of two or three treatments, spaced three to four weeks apart, is recommended for most clients. Single sessions produce improvement, but the cumulative effect of a course is meaningfully greater.

What to Expect at REGEN

All polynucleotide treatment at REGEN is administered by Dr Chris. The session involves a series of small injections across the treatment zone. A topical anaesthetic is applied beforehand to manage comfort. Some redness and minor swelling is normal in the hours immediately following treatment — most clients are comfortable returning to normal activities the following day.

The treatment itself takes approximately 30 minutes. Dr Chris will assess the treatment area and adjust the technique based on the specific concerns identified — the approach for under-eye treatment differs from facial treatment in terms of depth and technique.

Results build progressively. Most clients see meaningful change at four to six weeks, with continued improvement at three months. For a sustained outcome, maintenance treatments at six to twelve month intervals are usually recommended once the initial course is complete.
