What is Biyusen?

Biyusen™ is our first-born ingredient from biotechnology, and now the cornerstone of all our formulations. Crafted from Hokkaido's rarest moor hot spring, this vital healing elixir infuses every products with timeless, plant-derived potency.

One Place in the World

The hot spring of beauty

Hidden in the pristine forest of Hokkaido, the secret to beautiful skin was uncovered on the bank of the Tokachi River. There lies the one and only plant-based hot spring in Japan: Moor Onsen Water.

Inspired by the miraculous discovery of locals bathing in moor onsen water for naturally smooth skin, it hinted at a sacred skincare ingredient that was eventually created. This beautifying onsen water is the epitome of skin rejuvenation.

From onsen to our labs

Working with leading scientists from around the globe, we embarked on a quest to unlock the mystical healing powers of moor onsen water. Years of exhaustive research and countless experiments led to a breakthrough—a unique fermentation process transforming moor onsen water into BIYUSEN™, an organic compound of skin-renewing acids. This proprietary miracle complex, infused in all our formulas, is clinically proven to restore your skin to its healthiest state.

Fulvic acid

Enhances your skin’s natural defense mechanism as it is a powerful anti-oxidant. It also helps the absorption of oxygen and water.

Humic acid

Lengthens the life of hyaluronic acid molecules. This keeps the skin’s moisture level as high as possible and slows down wrinkle formation.

Hymatomelanic acid

Smooths and heals skin texture and accelerates the healing of superficial micro-wounds as well as cell renewal.
