About this episode

Most skincare is designed to improve how aging looks. But can it change what is happening inside the skin itself?In this conversation, I sit down with Carolina Reis Oliveira, PhD, co-founder and CEO of OneSkin, to explore what actually drives skin aging at the cellular level. Carolina explains how senescent “zombie” cells, UV exposure, inflammation, hormonal changes and a weakened skin barrier affect how skin functions, not just how it looks.Get OneSkin's new Rich Cream and the rest of the OS-01 line at:oneskin.co/KAYLA with code KAYLA.We break down the benefits and limitations of retinol, why chronic redness and flaking are not signs that a product is working better, and whether popular ingredients such as NAD+ precursors, methylene blue and GHK-Cu can penetrate the skin and remain stable. We also discuss collagen supplementation, red light therapy, hyperbaric oxygen, sauna, exercise, sun exposure and the relationship between skin-barrier health and systemic inflammation.Carolina also shares the science behind OneSkin's OS-01 peptide and its new Face Rich Cream, including findings related to collagen, hyaluronic acid, elastin, filaggrin, hydration, firmness and fine lines.In this conversation:-Why many anti-aging products target visible symptoms rather than the biology of skin aging -How senescent “zombie” cells contribute to inflammation and tissue decline -How to use retinol without chronically damaging the skin barrier-Why ingredient penetration, stability and formulation matter-How skin-barrier dysfunction may affect inflammation throughout the body-What collagen, red light, hyperbaric oxygen, sauna and exercise can do for the ski- What OneSkin found when testing GHK-Cu copper peptides-Why moisturizer alone may not solve age-related dryness-How OS-01 is designed to target the underlying biology of skin aging Join the most comprehensive *female-specific community for health and longevity optimization.* After over a decade dedicated to human performance and women’s health, I created this space to share everything you need to know to optimize health and lifespan.
