If you know Bobbi, you know she swears by Augustinus Bader’s moisturizer. This week, she’s joined by Charles Rosier, the investor-turned-beauty-entrepreneur who kickstarted the cult-favorite skincare brand. It all started when Charles saw how Dr. Augustinus Bader’s stem cell wound gel prevented scarring, and wondered if it would also work on wrinkles—and from there, the revolutionary skincare line was born. This week, Charles joins Bobbi to talk about the science behind the serums, how a beauty brand can help fund stem cell research, and why when it comes to brand-building, good luck is nothing without hard work.
