From Onsen to Our Labs
Working with leading scientists from around the globe, we hoped to unlock the mystical healing powers of the moor onsen water. Several years of exhaustive research and innumerable experimentation led to the breakthrough discovery—a fermentation process that transformed moor onsen water into an organic compound of skin-renewing acids called BIYUSEN™. This proprietary miracle complex, infused in all of our product formulas, is clinically proven to restore skin to its healthiest state.
