An Accidental Discovery
Our journey began when Eric Shinichi, the founder of IREN Shizen, visited a thermal resort in the mountains of Hokkaido, Japan. He accidentally discovered the secret to the locals' radiant skin: weekly baths in the regenerating thermal water known as "Bijin-no-yu," meaning "spring of beauty."
Fascinated by the regenerating effects on the skin, he was inspired to share this beauty secret with the world, infusing this legendary healing water into his skincare formulas, which led to the creation of BIYUSEN™.

From Onsen to Our Labs
Through the marvels of biotechnology, we have recreated this precious onsen water in our laboratories, preserving the purity and potency of every drop.
BIYUSEN™, this revolutionary lab-created ingredient, is now the central element of every IREN Shizen product, bringing the transformative powers of Japan's most exclusive onsen.
