Korean skincare is everywhere on social media — but how much of it is backed by real dermatologic science? In this episode of The Science of Skin Podcast, Dr. Patti Farris sits down with Dr. Jane Yoo, board-certified dermatologist, fellowship-trained Mohs surgeon, and "The K-Beauty Dermatologist," to separate fact from TikTok fiction.They trace K-beauty's roots from the Goryeo and Joseon dynasties through the Hallyu wave, then dig into the science: ceramide-dominant, barrier-centric formulations, low-pH cleansers, and why "glass skin" is more about consistent barrier care (and good lighting) than any single product. Dr. Yoo also breaks down the real evidence behind snail mucin, PDRN and PN, exosomes, and silica spicules — including where the hype outpaces the data — plus whether double cleansing is really necessary and why Korean sunscreen filters like bemotrizinol (Tinosorb S) may be the biggest public health advance in photoprotection in 25 years.In this episode:The real history of K-beauty, from royal court rituals to global exportWhat actually causes "glass skin" (and what doesn't)The truth about snail mucin, PDRN/PN, exosomes, and spiculesDo you really need to double cleanse?Why newly approved filters like bemotrizinol could change US sunscreensTinted, visible-light-blocking sunscreens for skin of colorHave a question or an idea for a future episode?Email [email protected] us at the Science of Skin Summit, September 17-20 in Austin, TX, or the new Science of Skin Longevity Conference in Scottsdale, February 2027.Learn more at scienceofskinsummit.comIf you enjoyed this episode, please leave a 5-star rating and share with a colleague — word of mouth helps our podcast grow!⚠️ This content is for educational and informational purposes only and reflects the personal clinical opinions and experiences of the speakers.
