Our name, pronounced SAY-soh, is inspired by the third of five principles in the Japanese 5S philosophy. The Seiso principle means “clean, tidy, and elegant.” The 5S philosophy emphasizes daily improvement, clearing away the unnecessary, and focusing on quality essentials.

The Story begins with a renowned Japanese scientist, Masakatsu Miyanabe , who leads the Genuine R&D Company in Japan. Mr. Miyanabe discovered a groundbreaking ceramide derived from Koji—unique in its ability to mimic the molecular structure of human skin closely. Collaborating with Rohto Pharmaceutical, a leading skincare technology company based in Osaka, Mr. Miyanabe developed this innovative ceramide into a skincare line deeply rooted in Japanese tradition yet uniquely suited to modern skincare needs. Departing from aggressive ingredient profiles and fleeting beauty trends common in American skincare, this collection offers a gentle, nurturing approach emphasizing simplicity, effectiveness, and timeless formulations.
Our modern collection is based in the sound, skincare science of Japan. We utilize patented technologies, advanced formulations, skin-loving textures and clean, sophisticated packaging. We follow a uniquely Japanese approach to skin wellness: nurture skin back to health. Our focus is on product performance, innovation, safety, sensuality and quiet luxury. We deliver measurable results, lasting improvements and skincare products that stand the test of time. Our goal is to make bare skin beautiful. Formulated, packaged and 100% Made in Japan.
