Japan's #1 Edible Serum that outsold bottles - made with the rarest beauty ingredient in the world.
LASIAL™ is clinically proven to help with the following:
- Radiant skin from within*
- Resilient Firmness*
- All-day hydrated skin*
LASIAL™ is protected under Japan Patent #7751161, using the world's only patented High Sialic Technology EBN Extract — delivering 5.89× more sialic acid and 257× greater antioxidant activity than standard EBN extract.
This patent covers the proprietary extraction process that makes LASIAL™ the only clinically validated edible serum of its kind on the market.
View Patent →BI-SU LASIAL™ Edible Serum is formulated to support healthy skin function, immune balance, and cellular vitality from within.* It was designed to promote lasting beauty and longevity via skin barrier repair, collagen protection, and regulatory immune support as part of a daily wellness practice.*
Sialic acid is a bioactive glyconutrient essential for cellular communication, skin regeneration, and immune regulation.* It maintains the glycan chains that act as your cells' antennae — repairing damage and coordinating the body's natural renewal process. Sialic acid levels naturally decline with age, contributing to weakened skin structure and reduced immune resilience.*
LASIAL™ — BI-SU's proprietary extract — is derived from 100% natural edible swiftlet's nest, the richest known source of sialic acid on earth, containing 200× more than royal jelly.* Paired with collagen peptides, snow mushroom, and vitamin C, it delivers what no topical can — restoring skin, immunity, and cellular health at the source.*

Why Japan eats its skincare
Skin is built to keep things out.

- ×Reapplied daily, forever
- Into the bloodstream in minutes
- Reaches the dermis
- One stick a day, since 1996
食べる美容液 — "the beauty serum you eat," as Japanese customers call it. Japan's first collagen supplement went on sale in 1996; the West got collagen powder around 2020.

LASIAL™'s patented EBN Extract penetrates deep into the dermis, activating skin-renewal pathways that topical serums simply can't reach.
By restoring key barrier proteins, LASIAL™ locks in moisture all day — reducing sensitivity and keeping skin resilient against environmental stressors.
