In this episode of The Healthspan Collective, host Nicole Doran sits down with Catherine Lockhart, clean beauty influencer, biohacker, and founder of Shelter Skin, to unpack why the wellness industry's most comforting labels are often its most misleading ones, and what it actually takes to build a truly low-tox life.
Catherine's journey began not in a lab, but in a Sephora aisle, surrounded by fragrance-heavy products she trusted completely. It wasn't until she came off birth control and began suspecting undiagnosed PCOS that she started questioning everything she was putting on her body. What followed was a deep dive into ingredient literacy, regulatory gaps, and the quiet ways everyday products can disrupt hormones, trigger brain fog, and undermine the very health we're trying to protect. She's since channeled that knowledge into Shelter Skin, a bootstrapped clean beauty brand formulated with naturals and scented with real vanilla bean infusion, built from conviction, not trend.
What we cover in this episode:
🏷️ Why "clean," "non-toxic," and "naturally derived fragrance" are largely unregulated marketing terms and how to see through them
🌿 A practical low-tox roadmap: where to start, what to prioritize, and how to maintain an 80/20 balance in the real world
🧴 How to actually read a label, spot greenwashing, and understand the gap between U.S. and EU cosmetic regulation
👗 PFAs in activewear, natural fiber alternatives, and the hidden toxins in everyday textiles
💉 Wedding skin prep without Botox, exploring Sofwave, microneedling, EasyGel, and why Catherine skips injectables entirely
✨ The story behind Shelter Skin, bootstrapping production, formulating with naturals, and scaling a clean beauty brand from the ground up
