Whitney Tingle sits down with Carolina Reis Oliveira, PhD—co-founder and CEO of OneSkin—to explore the latest science on skin aging, the role of senescent "zombie" cells, and how what we put on our bodies can be just as important as what we put in them. With a PhD in stem cell biology and a mission to help people live healthier, longer lives, Carolina shares her groundbreaking work on peptides, how the skin functions as part of the immune system, and which lifestyle and nutrition habits truly move the needle for vibrant, resilient skin at every age. This conversation is a must-listen for anyone who wants to understand the connection between longevity and beauty from the inside out.
