CO2 laser

Not all salmon DNA treatments are the same. PN and PDRN come from the same biological source but behave differently in tissue -- and those differences matter clinically. This article breaks down the molecular distinction between polynucleotides and PDRN, reviews what the current research actually supports, and explains why formulation choice by facial zone affects your outcomes. You'll also learn why timing your PN treatment before CO2 laser, Sculptra, or Radiesse can meaningfully amplify your results.
