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. We talk about melanin’s protective role, what happens in your skin after inflammation, how hormones and nervous system imbalances play a part, and why the microbiome is a missing piece in many skincare routines.

If you’ve struggled with dark spots, uneven skin tone, or want to support your clients in a smarter, safer way—this conversation is for you. We talk science, share practical tips, and explore gentle, microbiome-friendly ways to treat pigmentation without trauma.
