Even with gold-standard serums and disciplined ten-step rituals, results often plateau—a phenomenon known as tachyphylaxis, where the skin’s biology adapts to active ingredients. In this episode, I dive into the bioenergetics of aging and why your skincare plateaus may actually be a sign of Mitochondrial Burnout. I explore how we ca
