Episode 125 hosts Dr Hervé Raspaldo, a globally-renowned facial plastic surgeon based in Geneva, Switzerland. He specialises in surgical and non-surgical rejuvenation treatments of the face and neck and is especially known for his non-surgical rhinoplasty techniques. He is an international trainer and KOL for Vivacy, a French dermal filler company. We discuss the various types of fillers available on the market including the reversible as well as permanent types. We then explore filler rheology (the science of the physical properties of the materials) including cohesivity, elasticity, cross-linking and how these influence longevity and the patient experience.  Dr Raspaldo shares which filler brand he currently uses in addition to his experience with using 3D photography, ultrasound and MRI to track results and assess complications.     Show your support for IA via Patreon Follow IA on Instagram Visit our website  Subscribe to IA on Apple Podcasts Subscribe to IA on Spotify Contact Dr Jake & David  More about Dr Jake Follow Dr Jake on Instagram  Follow David on Instagram  Follow Hervé on Instagram: www.instagram.com/dr.raspaldo Visit his website: www.raspaldo.ch/en
