874: The Truth About Exosomes and Korean Skincare: A Cosmetic Chemist's Perspective
Episode 874
Tuesday, 13 October, 2026

Are you tired of falling for viral skincare trends that lack real scientific evidence? In this episode of Beauty Bytes, I am joined by J.C. Dombrowski, a Cornell-educated marine biologist, cosmetic chemist, and science communicator with nearly 3 million followers on TikTok. We dive deep into the reality of cosmetic chemistry and dismantle some of the most pervasive marketing myths in the beauty industry. J.C. shares his unfiltered, highly scientific perspective on why he believes topical exosomes are currently the biggest farce in skincare, explaining the biological impossibility of characterizing and keeping these complex messengers shelf-stable in a cosmetic formula. We also discuss the truth behind the Korean skincare hype, why the 500 Dalton rule is an over-extrapolated heuristic, and why a $1,200 luxury serum rarely outperforms a simple $10 prescription for tretinoin. Plus, we explore the complexities of claim substantiation, revealing why some "medical-grade" brands actually make the most biologically incoherent claims on the market. Guest Information:J.C.
