Listen on Apple Podcasts | Listen on Spotify

Forget botox and retinol. Peptides are changing the game in skincare longevity, and for the past six months, Erin’s best-kept skincare secret has been a science-backed line that doesn’t just improve how skin looks. It actually helps reverse its biological age!

In this episode, we’re uncovering ALL the groundbreaking research on peptides with OneSkin co-founder, scientist, and healthy aging advocate, Carolina Reis Oliveira, PhD.

Instead of quick fixes or invasive treatments, Carolina explains how their proprietary OS-1 peptide targets “zombie cells” (senescent cells) that accelerate skin aging and inflammation, helping restore healthier, more resilient skin.

From reversing fine lines and wrinkles to supporting scalp and hair vitality, this episode applies a functional approach to skincare to help you look and feel better at every age.
