Lactococcus Ferment Lysate
What is Lactococcus Ferment Lysate?
Lactococcus Ferment Lysate is a cosmetic ingredient obtained through the controlled fermentation of Lactococcus lactis, a lactic acid bacterium commonly used in food production. The process involves lysing, or breaking open, the bacterial cells to release intracellular components such as peptides, amino acids, polysaccharides, and metabolites. Primarily categorized as a skin conditioning agent in cosmetics, it functions by forming a lightweight film on the skin surface that helps lock in moisture and reinforces the natural lipid barrier. This mechanism supports skin's suppleness without greasiness, making it suitable for daily use in creams, serums, and masks. Derived biotechnologically, it offers a stable, non-living postbiotic alternative to whole probiotics, ensuring consistent performance in formulations.
