The Science Behind Aesthetics

Inflammation is one of the most misunderstood concepts in the aesthetic industry and in this episode, Nancy and Christoph go head to head with rapid-fire questions to unpack what it actually is, why it matters and where practitioners get it wrong.Nancy challenges Christoph on whether the biology really supports inflammation as a clinical endpoint. Christoph challenges Nancy on how she reads the skin in real time, how her approach has changed over 20 years and whether practitioners can actually predict who's going to be a difficult healer.Together they cover the fine line between therapeutic and excessive inflammation, why chronic inflammation is the real enemy, how to recognise a treatment gone wrong before it gets worse and the LED debate - should you use it straight after treatment or not?Honest, science-led, and grounded in real clinical experience. This is the conversation aesthetic practitioners need to have.Topics CoveredWhat inflammation actually is - and why it's not always the enemyAcute vs chronic inflammation and why the difference is critical in aestheticsInflammation as a clinical endpoint - does the biology support it?The right amount of inflammation - too little, too much and the fine line between themHow Nancy reads the skin in real time to identify the endpointAssessing clients before treatment - Fitzpatrick type, barrier health, medication, histamine responseWhy overtreating doesn't mean better results and what's actually happening in the tissueReactive skin - is it a biology problem or a behaviour problem?How Nancy's approach to inflammation changed over 20 years of practiceLED before or after treatment and why timing depends entirely on what you're trying to achieveWhat a treatment gone wrong actually looks like - and what to do immediately

Exosomes are rapidly becoming one of the most talked-about topics in aesthetics and regenerative skincare. They’re being infused post-treatment, incorporated into skincare and marketed as the next frontier in skin regeneration.But what are they actually?In this episode of The Science Behind Aesthetics, Nancy Abdou and Professor Christoph Hagemeyer unpack the biology behind exosomes and how they may influence skin repair and inflammation.Together they explore:• What exosomes really are and how cells use them to communicate• How exosomes are being researched in regenerative medicine• Their potential role in wound healing and aesthetic treatments• Plant-derived vs human-derived vesicles – are they biologically equivalent?• Delivery methods and whether they can penetrate intact skin• Why not all “exosome” products are created equal• The questions clinicians should be asking suppliersThis conversation bridges biomedical research and clinical aesthetics, helping practitioners better understand the science behind one of the industry’s fastest-growing trends.Because regenerative aesthetics should be driven by biology and evidence, not marketing claims.

In this opening episode of The Science Behind Aesthetics, hosts Nancy Abdou, founder of The Australian Dermal & Laser Institute, and Professor Christoph Hagemeyer, research academic and chemist, introduce the purpose and philosophy behind the podcast.Together, they discuss the growing gap between marketing, misinformation, and true scientific understanding within the aesthetic industry — and why education, evidence, and critical thinking are essential for safe, effective and ethical practice.This episode sets the foundation for future conversations exploring skin biology, skincare ingredients, aesthetic devices, emerging technologies, and professional education - always through a science-led lens.Disclaimer:This podcast is intended for educational purposes only.
