They are microscopic. They originated as ancient bacteria, and they quietly determine how your skin ages.

In this episode, I zoom in on one of the most important, and most overlooked, players in skin biology: the mitochondria. Often called the power plants of the cell, mitochondria produce the energy currency ATP that fuels every single process in your skin, from collagen synthesis and barrier repair to immune response and cellular renewal.

I explain why mitochondrial dysfunction is recognized as a central hallmark of aging, exploring the elegant Aging Spiral Theory by Dr. Masato Hiki, and share what mitochondrial decline actually looks like in the skin (dullness, thinning, slower renewal, loss of elasticity). I also cover exactly what you can do about it, from daily lifestyle habits to specific skincare ingredients that directly support mitochondrial health.

If you want to understand why your energy levels, your sleep, your sunscreen, and your antioxidants are all connected to how your skin ages, this episode will give you the science behind it.
