Growth Factors | PRF, PRP, and PDGF

March 18, 2025

In this episode, Dr. Kristen Herzog demystifies PRP (Platelet-Rich Plasma), PRF (Platelet-Rich Fibrin), EZ Gel, and PDGF (Platelet-Derived Growth Factors) – explaining the pros and cons of each treatment. You will learn about the history of the treatments and where the ideal injection sites are. The star of this episode is PDGF, as it’s been shown to be multiples above your natural growth factor concentration and thus much more effective than traditional PRP/PRF. However, if you’re looking to get your lips injected, Dr. Herzog still believes that traditional filler is the way to go.
