Key Ingredients
Powered by our encapsulated BIYUSEN™ technology and formulated with high potency of botanicals and science actives.

Visible Results
72 Hours Time Release
Our powerhouse serums host our very own patented Encapsulated Biyusen™ technology to timely unlock each ingredient’s actives, discharging them 10 times faster and deeper into skin cells. Each encapsulated active ingredient has a time release effect, allowing for higher concentrations without harming the skin. The nutrients are slowly released into the deeper layers of the skin, delivering long-lasting effects that can be observed for up to 72 hours.
Biyusen™ Onsen Water
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.
FAQ
Why are IREN Shizen serums customizable?
No two skins are alike. Just because your friend's skin responds well to a certain product doesn't mean it will be good for you. That's why we created seven serums with specific targeting functions, which serve up to 35 unique combinations for you to mix and match around for the tailored solution for your skin needs.
