Beleza by Z is skincare innovation rooted in a discipline the beauty industry too often overlooks: corneotherapy—the science of restoring the skin barrier as the foundation of long-term skin health. If your skin is inflamed, chronically dry, or stuck in a cycle of redness and irritation, you don’t need more “medical-grade” marketing buzzwords. You need formulas that speak the skin’s biological language. Instead of overloading formulas with harsh actives and botanical complexity, we take a precise approach built on one truth: the skin barrier is made of cholesterol, fatty acids, and ceramides—so skincare should be, too.
