What if your skin could literally rebuild itself from the inside out? In this episode, we break down one of the most powerful and misunderstood biological processes in the human body: autophagy.

From its Nobel Prize-winning discovery to the molecular machinery that drives it, we walk you through exactly what autophagy is, how it works at the cellular level, and why it matters far more than most people realize for skin aging.

We explore the two master switches that control autophagy, mTOR and AMPK, and how the constant tug of war between them determines whether your cells are in build mode or cleanup mode. We also explain why most people in the modern world are stuck in permanent mTOR activation, and what that means for how their skin ages over time.

This is Part 1 of our deep dive. In Part 2, we go skin-specific and break down exactly how autophagy renews your skin at the tissue level.
