How it works
Biome Shield 5X Cera Toner 150ml is a toner built on Ceramide AS, a barrier lipid from the ceramide family, named 9 of 29 entries on Bonajour's own manufacturer INCI for this formula. Ceramide AP runs alongside it, a barrier lipid from the ceramide family, and the rest of the list rounds out a Bonajour formula built for this format rather than a stripped-down version of it. It takes the first step after cleansing, and the toner format is the reason it behaves the way it does once it is on skin. A toner in this format is a thin liquid meant to sit on skin briefly and prep it for the layers that follow, not a step meant to linger.

Key actives
Ceramide AS
Ceramide AS is A barrier lipid from the ceramide family. It appears at position 9 of 29 on Bonajour's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Ceramide AP
Ceramide AP is A barrier lipid from the ceramide family. It appears at position 10 of 29 on Bonajour's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Ceramide NS
Ceramide NS is A barrier lipid from the ceramide family. It appears at position 11 of 29 on Bonajour's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Ceramide EOP
Ceramide EOP is A barrier lipid from the ceramide family. It appears at position 12 of 29 on Bonajour's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Is the Biome Shield 5X Cera Toner 150ml sold here Bonajour's Korean-market formula?
Yes. What ships is Bonajour's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the Biome Shield 5X Cera Toner 150ml go in a routine?
It takes the first step after cleansing. That placement follows from what a toner is, not from anything unusual about this specific unit. A toner in this format is a thin liquid meant to sit on skin briefly and prep it for the layers that follow, not a step meant to linger, so moving it earlier or later in a routine works against the format rather than with it.
What does Ceramide AS do in this toner?
Ceramide AS is A barrier lipid from the ceramide family. It appears at position 9 of 29 on Bonajour's own manufacturer ingredient list for this formula, which is real evidence of what the formula is built around rather than a marketing label placed over it.
Does the Biome Shield 5X Cera Toner 150ml contain fragrance?
No. Parfum and fragrance do not appear anywhere on the manufacturer's own ingredient list for this formula, which is one reason it reads as a shorter, calmer list than a heavily scented formula in the same category.
How does buying the Biome Shield 5X Cera Toner 150ml here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market Bonajour release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.
Amy Kassouf, MDDermatologist, Cleveland Clinic Pretty much every step of a Korean skin care routine is going to have some component of hydration.
