Carolina Reis Oliveira, PhD: Senescent Cells, Retinol Myths, and the Skin Barrier Body Connection

<p>Most skincare is designed to improve how aging looks. But can it change what is happening inside the skin itself?</p><p>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.</p><p>Get OneSkin&#39;s new Rich Cream and the rest of the OS-01 line at:</p><p>oneskin.co/KAYLA with code KAYLA.</p><p>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.</p><p>Carolina also shares the science behind OneSkin&#39;s OS-01 peptide and its new Face Rich Cream, including findings related to collagen, hyaluronic acid, elastin, filaggrin, hydration, firmness and fine lines.</p><p>In this conversation:</p><p>-Why many anti-aging products target visible symptoms rather than the biology of skin aging </p><p>-How senescent “zombie” cells contribute to inflammation and tissue decline </p><p>-How to use retinol without chronically damaging the skin barrier</p><p>-Why ingredient penetration, stability and formulation matter</p><p>-How skin-barrier dysfunction may affect inflammation throughout the body</p><p>-What collagen, red light, hyperbaric oxygen, sauna and exercise can do for the ski</p><p>- What OneSkin found when testing GHK-Cu copper peptides</p><p>-Why moisturizer alone may not solve age-related dryness</p><p>-How OS-01 is designed to target the underlying biology of skin aging<br></p><p>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.
