Collagen is everywhere—supplements, skincare, treatments—but do you really know what it is or how it works?

In this episode, I break down the complex science of collagen in the skin. I explain the different types, how collagen production changes over your lifetime, what damages it (spoiler: it’s not just aging), and how to protect and rebuild it using evidence-based skincare, microbiome support, and smart lifestyle choices. A must-listen for anyone curious about how to keep skin firm, resilient, and glowing at every age.

Pigmentation is one of the most misunderstood skin conditions and also one of the most emotionally challenging. In this episode, I’m joined by my friend and incredible aesthetician, Sarah Drew, to talk about the real reasons behind pigmentation.

Retinol changed the skincare world when it first appeared — but today, I believe we can do better.

From biotech innovations to plant-derived molecules, I explain how we can achieve beautiful, healthy skin without the irritation or risks.

Stress is part of life—but it doesn’t have to take a toll on your skin.

In this episode of the Meder Beauty Podcast, I talk about how stress affects the skin on every level—from hormones and the nervous system to collagen, the microbiome, and skin barrier health. I explain why stress can trigger conditions like acne, pigmentation, sensitivity, or early signs of aging—and how we can gently support the skin to become more resilient.

I also share simple, science-backed ways to calm your skin’s stress response, including how activating the vagus nerve with cold water or breathwork (and yes, even love and oxytocin!) can help your skin stay balanced, calm, and radiant.
