Reactive Skin Lab: The Science Behind Eczema, Rosacea, and Inflammation

Your skincare routine is thorough. Cleanser, toner, serum, moisturizer. And yet your skin still isn't behaving the way you want it to. You've swapped products, simplified, added back, and you're still troubleshooting. Nobody has suggested that your routine itself might be the problem.

Your skin hosts a complex microbial ecosystem that regulates barrier function, inflammation, and resilience. Research over the last decade has made clear that many conventional skincare ingredients, including common preservatives, surfactants, and synthetic fragrances, disrupt that ecosystem in ways that create the exact problems they claim to solve. Understanding the microbiome changes how you think about everything on your shelf.

In this class you'll learn what the research shows about the skin microbiome and barrier function, then make two products designed to support rather than disrupt. You'll leave with both, and a completely new framework for evaluating everything else in your routine.
