Exosomes vs PDRN: Choosing the Right Regenerative Injectable for Your Patient
Two of the most clinically significant injectable categories in modern aesthetic medicine — polynucleotides/PDRN and exosomes — are frequently compared by practitioners trying to determine which to offer, which to prioritise for specific patients, and whether there is clinical value in using both. The comparison is worth making carefully, because the two treatments operate through genuinely different mechanisms, have different evidence bases, suit different patient profiles in some respects, and produce their best outcomes in different clinical contexts.
Exosomes for Skin Rejuvenation: Clinical Evidence and Treatment Protocols
Exosomes represent the most mechanistically sophisticated tool currently available for skin quality rejuvenation. Where hyaluronic acid skin boosters deliver hydration and PDRN activates the adenosine A2A receptor, MSC-derived exosomes deliver a complex biological payload — growth factors, microRNAs, and signalling proteins — directly into recipient skin cells
PDRN for Acne Scars: Clinical Protocol and Evidence
Acne scarring is one of the most emotionally significant skin concerns that patients bring to aesthetic consultations. Studies consistently show that acne scars — even mild to moderate ones — have a disproportionate impact on psychological wellbeing, self-confidence, and quality of life relative to their objective severity. Patients who have lived with acne scarring for years often arrive at consultation having accepted that 'this is just how my skin is' — and the knowledge that effective treatments exist is genuinely life-changing for many of them.
Polynucleotides and PDRN: The Complete Practitioner's Guide
Polynucleotides — sold under a variety of brand names and delivered through a growing range of injection products — have become one of the most talked-about categories in UK aesthetic medicine. They are also one of the most misunderstood. Practitioners encounter them under different terminology (PDRN, PN, polynucleotide, polydeoxyribonucleotide), from multiple manufacturers, with variable claimed mechanisms, and with an evidence base that ranges from well-established to preliminary depending on the specific application and product.
