Bifida Ferment Lysate and Bifida Ferment Lysate Liquid refer to the same bioactive ingredient, but the terms are used differently depending on form, processing stage, and cosmetic labeling practice. Here’s a clear, practical comparison.
1. What They Have in Common
Both are derived from Bifidobacterium (usually Bifidobacterium longum) through:
(1) Cultivation (fermentation)
(2) Cell disruption (lysis)
(3) Removal of live bacteria
They contain:
- Cell wall fragments
- Peptides & amino acids
- Polysaccharides
- Nucleotides & metabolites
�� No live probiotics – they are postbiotics.

2. Key Differences
| Aspect | Bifida Ferment Lysate | Bifida Ferment Lysate Liquid |
| Nature | Ingredient name (INCI) | Physical form of the ingredient |
| Physical state | Usually concentrated, may be liquid or dried | Always liquid |
| Solvent | Not specified | Water / glycerin / butylene glycol |
| Activity | Same biological activity | Same biological activity |
| Use in formulations | Listed on ingredient label | Used as supplied by raw material vendor |
| Concentration | Can be high or standardized | Usually diluted or standardized |
3. Why “Liquid” Is Sometimes Added
Manufacturers or suppliers add “Liquid” to clarify that:
- The ingredient is supplied as a ready-to-use aqueous solution
- It is not a powder or dried lysate
- Easier incorporation into serums, essences, and ampoules
INCI labeling:
Even if the raw material is liquid, the correct INCI name is still:
“Liquid” is not part of the official INCI name.
4. Functional Effects (Same for Both)
Whether liquid or concentrated, benefits are identical when used at equivalent active levels:
- Strengthens skin barrier
- Enhances DNA repair after UV exposure
- Improves skin resilience
- Reduces sensitivity & inflammation
- Supports microbiome balance
- Anti-aging and skin recovery benefits

5. Typical Usage in Cosmetics
- Use level: 1–10% (liquid form often higher due to dilution)
- Formulation types: serum, essence, ampoule, cream, mask
- pH compatibility: ~5.0–7.0
- Heat sensitivity: Add below 40 °C
6. Summary
- Bifida Ferment Lysate = ingredient name
- Bifida Ferment Lysate Liquid = supplier’s physical form
- Function, efficacy, and safety are the same
- “Liquid” is a commercial or technical descriptor, not a regulatory one
