Hinou Dokon 皮膚脳同根: Skin-mind, same root An ancient Japanese principle recognizing the body and mind as inseparable. Today, neuroscience and dermatology confirm this principle: the brain and skin both share signaling pathways. In Japan, skincare has never been only cosmetic. Rituals for the skin are rituals for the mind, and caring for the mind reflects back on the skin. In honor of World Mental Health Day, we’re proud to partner with @op_e___n. Together, we created “In Your Skin,” a 7-day meditation and breathwork program on the Open app, designed to help you pause, alleviate stress, and reconnect with yourself. Because when the mind is calm, the skin reflects it. Download the @op_e___n app today and head to Tatcha.com to learn more.
