Lactococcus Ferment Lysate is produced by fermenting and lysing Lactococcus bacteria — a lactic acid bacteria genus used extensively in dairy fermentation. The lysate releases cell wall fragments, peptides, and metabolites that signal the skin's immune system to strengthen barrier function and reduce inflammation. Similar in concept to Bifida Ferment Lysate but derived from a different probiotic genus with distinct signaling molecules.
Key Skin Benefits
+ Supports skin immune and barrier function
+ Anti-inflammatory signaling molecules
+ Gentle — lactic acid bacteria derived
+ Microbiome-friendly lysate
+ Complements other probiotic ferments
Pros
+ + Probiotic-derived lysate

+ + Gentle and well-tolerated
+ + Synergistic with other ferments
+ + Dairy-safe (no milk proteins)
Cons
− − Less studied than Bifida/Lactobacillus
− − Quality varies by fermentation
− − Requires preservation
