About Bi-Su

About BI-SU – https://bisu-us.com

Regenerative Beauty, Powered by Nature and Science

At BI-SU, we believe beauty begins at the cellular level—where renewal and vitality are created.

Founded on science and nature, BI-SU redefines beauty as regenerative inner care, supporting your skin’s natural ability to renew from within.

For women seeking more than surface solutions, BI-SU offers a deeper approach to lasting beauty.

From a White Jewel of Nature

For over 1,000 years, swiftlet’s nest has been treasured by royalty as a symbol of beauty and longevity. Known as the “White Jewel,” it is a rare natural substance unlike anything found in modern beauty.

BI-SU uses 100% wild, natural swiftlet’s nest sourced from limestone caves in Borneo, Malaysia—harvested only after the birds have safely left, preserving nature’s cycle.

This is not marketing.
It is the foundation of BI-SU.

Committed to Conservation

We support local conservation in Borneo and certified by Malaysian government for ethical sourcing.

Protecting Rainforests

We donates and participates in tree-planting initiatives, working to restore vital ecosystems.

Humane Charity

We develop and donate nutrient-rich food support to children in conflict-affected areas.

Bio-Sustainable. Ethical. Cruelty-Free.

Our nests are responsibly hand-harvested only after they’ve been naturally abandoned. This creates space for swiftlets to rebuild. We also support habitat conservation through ongoing donations.

Inatomi Mikiya

BI-SU was created from a simple belief: true beauty and health can only exist when nature, science, and integrity are in balance.

After witnessing the power of natural swiftlet’s nest—and the damage caused by shortcuts and imitation—Inatomi set out to protect what is real and reveal its full potential through research.

His vision is to build a regenerative brand that respects nature, advances science, and delivers benefits that endure—inside the body and beyond it.

BI-SU GINZA SIX

A refined space inspired by nature and purity, rooted in the rare natural swiftlet’s nest. Experience inner care tastings and the full skincare collection, where science and nature meet.

Bi-Su Questions & Answers

Q: Where do these Bi-Su offers come from?

A: Offers come from a mix of sources: promotions published on the Bi-Su website, campaigns shared publicly, and codes provided directly to CouponNo1. Details are always worth checking against the Bi-Su terms before you buy.

Q: How do I use a Bi-Su coupon code?

A: Click GET CODE on the offer you want. A window opens showing the code - click Copy, then click Go To Store. Add your items to the cart at Bi-Su, then paste the code into the promo or discount code field at checkout and apply it before completing your order.

Q: What is the difference between GET CODE and GET DEAL?

A: GET CODE appears on offers that need a code entered at checkout. GET DEAL appears on offers that apply without one, such as a sale or a price already reduced. Both take you to the Bi-Su website.

Q: Will all Bi-Su discounts apply automatically at checkout?

A: No. It depends on the offer. Some need a code entered in the discount field, and some apply on their own. The button on each offer tells you which is which.

Q: Why didn't my Bi-Su coupon code work?

A: Offers often carry conditions - a minimum spend, selected products only, new customers only, a specific payment method, a regional limit or an expiry date. Merchants can also end a promotion at any time without notice. If a code doesn't apply, come back to this page and try another offer, or switch the filter to Sales.

Q: How do I check that a Bi-Su discount was applied?

A: After entering the code at checkout, look at your order summary before paying. An applied discount normally shows as a separate line and a reduced total. If the total hasn't changed, the code hasn't been accepted.

Q: How long are Bi-Su offers valid?

A: Validity is set by Bi-Su, not by CouponNo1. Where an end date is provided it is shown with the offer. Where none is given, the offer may end at any time without notice.

Q: How do I know whether an item qualifies for a Bi-Su offer?

A: Check the offer details on this page first, then the terms on the Bi-Su website. Promotions are often limited to certain products, categories or collections, and sale items are frequently excluded.

Q: How do I find a Bi-Su free shipping offer?

A: Free shipping offers, where Bi-Su is running one, appear in the list on this page. Check the conditions attached - free shipping usually requires a minimum order value or applies only to certain delivery areas.

Q: Can I use more than one Bi-Su coupon code on an order?

A: Most retailers allow only one code per order. Whether codes can be combined is decided by Bi-Su, so check their terms before assuming a second code will apply.

Q: When is the best time to look for Bi-Su offers?

A: Retailers generally run more promotions around major shopping periods such as Black Friday, seasonal sales and end-of-season clearances. Outside those periods, offers appear at no fixed schedule.
