Polynucleotides (PN) are nucleotide-based products increasingly used within aesthetic practice for skin-quality and regenerative treatment strategies. They are distinct from hyaluronic acid skin boosters and structural dermal fillers, and practitioners should evaluate each PN or PDRN formulation on its own evidence, intended purpose and manufacturer documentation.
For a direct comparison with the wider skin-quality category, read our Skin Boosters: A UK Practitioner Guide.
What Are Polynucleotides?
Polynucleotides are chains of nucleotides. In aesthetic products, PN and PDRN are discussed in relation to tissue-quality and regenerative pathways. The terms are sometimes used loosely in marketing, but they should not be assumed to describe identical materials or formulations.
PN vs PDRN: Are They the Same?
They are related nucleotide-based materials, but terminology, molecular characteristics and formulations can differ. Practitioners should rely on the specific product’s documentation rather than treating PN and PDRN as universally interchangeable.
What Does the Evidence Show?
The clinical literature around PN/PDRN in dermatology and aesthetic medicine is developing. Published studies and reviews report promising applications, but the evidence base remains heterogeneous, with variation in formulations, study designs, protocols and outcomes.
This means evidence for one product or formulation should not automatically be extrapolated to every polynucleotide product on the market.
Polynucleotides vs Skin Boosters
HA-based skin boosters are generally associated with hydration and skin-quality support. Polynucleotides are chemically distinct and are positioned around tissue-quality and regenerative pathways. Both categories contain different formulations, so the most useful comparison is product-specific rather than simply asking which category is “better”.

Polynucleotides vs Profhilo
Profhilo is an HA-based bio-remodelling product, whereas polynucleotides are nucleotide-based. They may be considered within the same broad skin-quality conversation but should not be presented as equivalent products.
Practitioners can also read Profhilo vs Dermal Fillers to understand how bio-remodelling differs from structural filler treatment.
How Should Practitioners Evaluate Polynucleotide Products?
- Identify the exact formulation: do not rely only on the words PN or PDRN.
- Review product-specific evidence: separate ingredient-level research from evidence for the finished product.
- Check intended purpose and manufacturer information: indications, contraindications, protocol and storage requirements can vary.
- Assess training and competence: practitioners should be appropriately trained for the procedure and product they provide.
- Verify provenance and traceability: maintain appropriate batch, expiry and procurement records.
Where Do Polynucleotides Fit in a Clinic Range?
They can provide a distinct skin-quality category alongside HA skin boosters and structural fillers. A focused range is usually easier to understand, stock and reorder than multiple overlapping products with no clearly defined role.

Frequently Asked Questions
Are polynucleotides dermal fillers?
No. Polynucleotide products are chemically distinct from conventional HA dermal fillers and should not be treated as structural volumising fillers.
Are polynucleotides the same as skin boosters?
They are often grouped commercially within the broader skin-quality market, but they are distinct from HA-based skin boosters in composition and proposed mechanisms.
Is there evidence for polynucleotides?
There is a developing clinical literature, but the quality, formulations and protocols vary. Practitioners should assess evidence relevant to the individual product rather than assuming all PN/PDRN products have an identical evidence base.
