Common Name(s): Lactococcus ferment extract,lactococcus ferment extract,lactococcus postbiotic ferment,biotransformed active filtrate
CAS Number: N/a
DESCRIPTION
What It Does: Provides lactococcus-specific postbiotic metabolite profile alongside substrate-biotransformed actives with enhanced sc penetration.
Why It's Used: Lactococcus ferments deliver unique organism-characteristic metabolites in a stable cosmetic format — the organism selection determines the distinctive bioactive profile beyond standard fermentation.
How It Works: Lactococcus fermentation: homofermentation → nisin bacteriocin (broad-spectrum gram-positive antimicrobial) + lactic acid + co₂.
