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.

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.
How do I know which serums are the best for me?
Our resident dermatologist has developed an online quiz that considers your skin concerns, background, and lifestyle. This quiz asks the same questions that she would ask a patient in the clinic to determine the best serums to meet your needs. You can take the Skin Quiz to find out which serums are most effective for you.
Do I have to mix the different serums?
To get the best results, we recommend mixing different serums from our collection. You can use them alone or layer them, or even combine up to three serums. We found through research that many people have multiple skin concerns at once, so mixing can address those concerns simultaneously. Our serums are encapsulated, which means they can be mixed without losing efficiacy. The encapsulation technology keeps the active ingredients fresh, separate, and prevents oxidation.
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 for 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 seeing the result?
Everyone's skin is different, so the results vary depending on your skin health. For the average adult, it takes around 28 days for skin cells to turn over, so, as a general rule of thumb, you should only start to see real changes in your skin after between four to six weeks of consistent use.
Can I use the serums around my eyes?
Yes, as long as you have chosen a suitable formulation for your skin. There are three serums that are specially formulated to address under-eye concerns.
- FOREVER YOUNG Anti-Aging Serum contains multiple peptides that lift sagging skin and reduce fine lines around the eyes.
- SKIN REBOOT Antioxidant Serum contains a caffeine solution that reduces eye puffiness and improves circulation to lighten dark eye circles.
- QUENCH-UP Hydrating Serum contains hyaluronic acid that restores lost skin moisture and rejuvenates the delicate skin around the eyes.
