- Origin: Fermentation product of Bifidobacterium
- Category: Postbiotic / Bio-ferment
- Appearance: Light yellow to brownish liquid or powder (depending on form)
- Solubility: Water-soluble
2. Source & Production
Bifida Ferment Lysate is obtained by:
- Culturing Bifidobacterium through controlled fermentation
- Lysing (breaking down) the bacterial cells
- Filtering and purifying the resulting bioactive components
The final ingredient does not contain live bacteria, making it safe and stable for cosmetic use.
3. Key Components
- Peptides
- Amino acids
- Nucleotides
- Vitamins
- Cell wall fragments
- Fermentation metabolites
These components work synergistically to support skin health.
4. Main Functions in Skincare
- Skin barrier repair – strengthens the stratum corneum
- Enhances skin resilience – improves resistance to environmental stress
- Anti-aging support – helps reduce fine lines caused by damage
