The next frontier for ingestible beauty - made with the rarest 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.*
