## Resource

Salmon sperm in your skincare? It sounds wild, but PDRN (polydeoxyribonucleotide) is everywhere right now — on your For You page, in Korean skincare hauls, and yes, Kim Kardashian had it injected into her face. In this episode, Dr. Mary Alice Mina cuts through the hype and gives you the full, unfiltered picture on what PDRN actually is, where it comes from, and what the science really says. Dr. Mina breaks down the two proposed mechanisms behind PDRN — the adenosine A2A receptor pathway and the salvage pathway — and explains why the concept is genuinely exciting on paper. But she also walks through the critical limitations in the research: most studies are in vitro or in animal models, and the most compelling human trial was done on diabetic foot ulcers — a very different biological situation than healthy skin aging. She addresses the big practical problem with topical PDRN: the molecule is large and negatively charged, meaning your skin barrier (doing its job) likely blocks most of it from penetrating to where it needs to work. She also flags a major labeling issue — some popular "PDRN" products are actually plant-based, which uses an entirely different molecule that can't be compared to salmon-derived PDRN research. And many of these products are packed with well-studied supporting ingredients like niacinamide and ceramides, which may be doing the real heavy lifting. Dr. Mina's bottom line: PDRN may have a future, but we're not there yet. Before spending money on the trend, double down on what we know actually works — retinoids, sunscreen, ceramides, sleep, and a healthy diet.
