| What it is | The ferment that made 'microbiome skincare' a shelf category. Bifida ferment lysate is a processed bacterial culture — nothing is alive by the time it reaches the bottle — used as a conditioning ingredient in essences and barrier creams. | One of the bacterial ferments Korean brands use when they want to say microbiome without saying anything checkable. What reaches the bottle is a filtered soup of peptides, sugars and acids — nothing living. It behaves as a conditioning agent. Claims that it rebalances your skin's own microbial population are well beyond what has been shown. |
| Best for | Damaged moisture barrier, Dullness & glow, Anti-ageing & firmness | Damaged moisture barrier, Dullness & glow, Reactive & easily-stung skin |
| When to use | BOTH | BOTH |
