The 19th Century Discovery Behind the Future of Skincare

Send us Fan MailThe word microbiome is everywhere now. But the science behind it goes back much further than most people realize, all the way to a Ukrainian soil scientist in the late 19th century and a Nobel laureate who promoted yogurt as a longevity tool long before we had a word for probiotics.In this episode, I explore dysbiosis, the disruption of the microbial community living with your skin, which was officially added to the twelve hallmarks of aging in 2024. I begin with the historical roots of microbiome science, from Sergei Winogradsky's soil ecosystems to Élie Metchnikoff's revolutionary ideas about gut bacteria and aging, and trace the path to the Human Microbiome Project launched in 2007 that mapped the microbial life of the entire human body.I explain what a healthy skin microbiome actually looks like, why it follows what I call the Anna Karenina law, and how age-related dysbiosis shifts the microbial community from protective to pro-inflammatory. I also cover the gut-skin-brain microbiome axis, the phenomenon of leaky gut, and what both mean for visible skin aging. And finally, the practical strategy: how nutrition, lifestyle, and the right topical ingredients (prebiotics, probiotics, biofermented extracts, and the new generation of agebiotics) can restore microbial balance and actively support skin longevity.Episode resources:Shannon-Weaver indexAdvanced Biohacking Anti-Acne Skincare RoutineHallmarks of aging: An expanding universe by Carlos López-OtínHuman Microbiome Project (HMP)Recycling Metchnikoff: Probiotics, the Intestinal Microbiome and the Quest for Long LifeSergei Winogradsky: a founder of modern microbiology and the first microbial ecologistSome indigenous people from the Amazon have the richest and most diverse microbiota ever recorded in humansTesting the Anna Karenina Principle in Human Microbiome-Associated DiseasesLearn more from the previous episodes: Epigenetic Skincare: Can We Reprogram How Our Skin Ages?The Hidden Inflammation Accelerating Your Skin AgingZombie Cells Are Aging Your Skin: Here's How to Stop ThemSun Protection Strategy: More Than Sunscreen!Shop the skincare we talked about today: Vita-Long - Advanced skin longevity careConnect with us:Meder by Dr. Tiina MederMeder Beauty InstagramMeder Beauty FacebookMeder Beauty TikTokMeder Beauty LinkedInMeder Beauty YouTubeListen to the Meder Beauty Podcast on Apple Podcasts
