OUR AMBASSADOR Neuroscience Expert Dr. Claudia Aguirre A pioneering scientist studying the brain-skin connection for nearly two decades, she’s helping us change the way we care for our skin and ourselves. LEARN MORE

“As a neuroscientist and mind-body expert, I’ve long studied how our inner world shows up on our outer selves. What drew me to working with Tatcha is that their approach to skin is rooted in the same biological truth I’ve spent my career exploring: the skin and mind are not separate systems, but a single, continuously communicating one.  ​ Hadasei-3 and their NeuroSkin Science framework reflect a formulation philosophy that takes this connection seriously, one where a skincare ritual is an act of tending to the whole self. The concept of hinou-dokon isn’t just Japanese wisdom, it’s increasingly what the science confirms.” Dr. Claudia Aguirre LEARN MORE
