Our Story

We create skincare that brings nature’s healing powers closer to you.

The Secret of Japan

Centering on age-old Japanese concepts and beauty rituals, IREN Shizen envisages an era of inspiring beauty in its simplicity and naturalness. Determined to draw from the spirit of nature to heal skin and soul, our skincare journey begins with the relentless search for nature’s unseen miracles, which led to a miraculous discovery—the rarest plant-based hot spring water with only two of its kind in the world. Moor Onsen Water would ultimately transform skin to its softest, silkiest and healthiest state. 


This proprietary complex of actives is the cornerstone of our skincare. Derived from the rarest plant-derived moor hot spring in Hokkaido, this wonder water is found in only one location in Japan—carefully integrated into the heart of every IREN Shizen products today.

Nature's Healers

We conscientiously formulate every product with the finest selection of nature-derived ingredients sustainably sourced from Japan, creating the ultimate efficacious skincare that is gentle to your skin and the environment.

Unseen Beauty of Healing

Inspired by the Japanese philosophy of “unseen beauty”, we firmly believe in the connection between inner and outer beauty. We craft mindful skincare regimens to nourish not just the skin, but also the state of mind.


We deeply care about the environment around us and all living things—from animals to communities. Embracing Japan’s affinity and affection with nature, we are actively taking steps to reduce carbon footprint and practices that are harmful to nature.
