Episode Description from the Publisher

In this special episode, we're joined by Rita Silva, Acting Director of Scientific Communications at DECIEM, for a deep dive into the science behind The Ordinary's popular peptide serums. From Multi-Peptide and Matrixyl to Argireline and the latest plant-derived growth factors, we're getting into the formulation history, clinical research, and what these products can realistically do for your skin. And of course, we have to tackle some of your biggest peptide questions. Can you mix copper peptides with vitamin C? Are peptide serums worth adding to a retinoid routine? And where should a peptide beginner even start? #skincarescience #sponsored #peptides #cosmeticchemist
