Nature's Healing Water of Japan


The story of BIYUSEN™ started in a faraway plant-based hot spring in Hokkaido, where a chance observation of the locals' flawless skin led to the creation of IREN Shizen's iconic ingredient. Infused with a organic blend of cell-renewing acids, this luxurious bio-ingredient gently exfoliate to reveal translucent complexion that transcends age. With more than 70% of BIYUSEN™, every drop of the serum leaves skin feeling fresh, touchably soft and hydrated.

Made to Personalize

All skin is unique. Rather than defining skin through general skin type, effective skin treatment requires a perfect-fitting solution that treat specific skin conditions. Our 7 customised serums are purposely crafted with the purest and highest grade of active ingredients tailored to unique skin concerns, scientifically proven to always deliver visible results. Take the skin quiz expertly designed by our scientists and dermatologists for you to curate the precise serum combination for a more plumped and youthful complexion.

How to Use

Use in the morning and night after cleansing or/and toning face. Dispense 3-4 drops onto palm and gently pat in serum across the face and neck. Use alone or mix up to 3 serums according to your needs.


Do I have to mix the different serums?

Not a must, but it is highly recommended. The serums can be used alone, layered or mixed up to 3 serums. It is possible to mixl 3 of them in one single step for the complete Japanese personalised skincare ritual experience.

Why are IREN Shizen serums customizable?

We created 7 serums with specific targeting functions, which serve up to 35 unique combinations for you to mix and match around for the perfect solution for your skin needs..

With our Encapsulation™ Technology in play, all our serums are customizable with no contradiction of active ingredients and no compromise on efficacy. We recommend mixing up to 3 serums to create a personalised treatment to enhance your skincare ritual. 

Why is it advisable to mix up to 3 serums only?

We have performed countless tests to determine the optimal amount of active ingredients needed to have the best results. Adding more serum to the mix will mean that the amount of active ingredients in each serum will be too little to have a good effect on the skin.

How often do I need to use the serums before I see the result?

We recommend incorporating our serums twice a day into your skincare routine. You’ll start to see results after four to six weeks of regular use.
