Awaken Your Natural Glow with BIYUSEN™

The story of IREN Shizen began with our visionary scientists as they unraveled nature's best-kept secret: an enchanting water sourced from rare Japanese "moor" onsen hot springs. Overflowing with lavish doses of natural moisturizing and anti-aging ingredients, it unveils a complexion so silky-smooth, you'll feel like royalty.

Years of research were invested to perfect an intricate alchemy process – one designed precisely for transforming this extraordinary "moor" onsen water into something truly extraordinary. This metamorphosis gave birth to BIYUSEN™ - an organic compound teeming with skin-renewing acids unparalleled in their transformative powers. This exclusive miracle complex, infused in all IREN Shizen products, is clinically proven to restore your delicate skin back to its optimum splendor.
