The journey begins at the Musée Fragonard in Paris, a "library of flesh" where the 18th-century flayed masterpieces of Honoré Fragonard reveal the intricate, visceral beauty of the body stripped of its skin.

This episode explores the skin not just as a static covering, but as a feat of biological engineering—a "living armour" that serves as our primary defense against the outside world.

We examine the complex architecture of this organ, from the waterproof barrier of the epidermis to the deep, supportive structures that allow it to heal and breathe.

Beyond its physical structure, the skin is a thriving "living planet," home to a vast universe of microscopic life.

We dive into the hidden battleground of the skin microbiome, where beneficial microbes stand guard against opportunistic predators like Staphylococcus aureus.

Discover how these tiny residents can become "villains" when our defenses are breached, and how our skin remains in constant, secret communication with the deepest territories of our bodies.

Join us as we begin to map the endlessly complex world that sits at the very edge of our existence.
