Postbiotic ferment filtrate
Bifida Ferment Lysate
INCI: Bifida Ferment Lysate·Studied at commonly 5% and up; K-beauty ampoules disclose 40 to 90%·Moderate evidence
A postbiotic made by fermenting Bifidobacterium and breaking the culture down into a filtrate of amino acids, peptides, sugars and nucleotides. It is the hero of several prestige "repair" serums and now shows up at high percentages in K-beauty ampoules, used for the appearance of a stronger, more resilient-looking barrier and a smoother surface.
Studied for
- ·The appearance of a resilient, comfortable-looking barrier
- ·The look of smoother, more even texture
- ·Supporting skin's visible recovery from daily environmental stress
How it’s thought to work
Studied as a soothing, barrier-supporting postbiotic: the ferment metabolites are associated in research with a better-looking moisture barrier and reduced visible sensitivity. It is a lysate, not a live culture, so there are no living bacteria in the bottle.
Questions
- Are there live probiotics in it?
- No. It is a lysate, meaning the fermented bacteria have been broken down and filtered, so what is left is the metabolites (a postbiotic), not living cultures. That is why it stays stable in an ordinary serum.
- Is this the ingredient in the famous prestige repair serum?
- It is the same class of active. Several high-end "repair" serums are built on a bifida or related ferment lysate, and a number of K-beauty ampoules now use it at high disclosed percentages for a fraction of the price.
- How does bifida ferment lysate compare with other postbiotic ferments?
- It is one of several postbiotic ferment lysates on the market (bifida, lactobacillus and others), and they are generally used the same way and marketed for similar barrier-support and soothing claims. Formulation quality and disclosed percentage tend to matter more than which specific bacterial strain the lysate started from.
