Ron Robinson is the founder of BeautyStat and the cosmetic chemist behind Hailey Bieber’s skincare line, Rhode. Robinson began his career at Clinique in the ’90s and, over the past two decades, has worked on products for industry giants like Revlon, Avon, L’Oréal, and Lancôme. He launched BeautyStat as an educational platform for beauty enthusiasts in 2009 but ultimately moved into developing his own product line in 2019 with the launch of his groundbreaking, ultra-potent vitamin C formulation. Celebs took notice, and Hailey Bieber quickly reached out to bring him on as a partner in what would become Rhode. In this episode, Robinson chats with Who What Wear Beauty Director Erin Jahns about the science behind successful products and which ingredients are worth the hype.
