Common Name(s): Leuconostoc ferment lysate filtrate,leuconostoc species (heterofermentative lactic acid bacterium) ferment,general substrate (lysate form) ferment filtrate
DESCRIPTION
What It Does: Delivers bioactive compounds from leuconostoc species (heterofermentative lactic acid bacterium) fermentation to condition and support skin health.
Why It's Used: Fermentation of general substrate (lysate form) by leuconostoc species (heterofermentative lactic acid bacterium) produces enriched filtrate with enhanced bioavailability of skin-beneficial compounds.
How It Works: Microbial fermentation transforms general substrate (lysate form) components into smaller, more bioavailable peptides, organic acids, and metabolites that support skin barrier function and microbiome balance.
