Is Your Sunscreen Actually Safe? | Sarah Miller

Is your sunscreen really protecting your skin—or could it be exposing you to unnecessary chemicals while harming the environment? In this episode of The Practice Pulse, host Nancy Margrit sits down with Sarah Miller, CEO and founder of EthoSun, to explore the science, myths, and misconceptions surrounding sunscreen and clean beauty. After undergoing multiple brain surgeries and radiation treatment, Sarah's perspective on health changed forever. That personal journey eventually led her to create EthoSun—a clean sun care brand built around transparency, non-nano mineral ingredients, and environmental responsibility. Together, Nancy and Sarah discuss why reading ingredient labels matters, what "reef-safe" really means, and why consumers should ask more questions about the products they put on their skin. Whether you're passionate about skincare, wellness, sustainability, or building a purpose-driven business, this conversation offers valuable insights into creating products that prioritize both people and the planet.
