Lactobacillus Ferment Lysate is obtained by optimized fermentation of Lactobacillus pentosus. Lactobacillus Ferment Lysate improves the function of the skin barrier by increasing the formation of tight junction proteins, which contribute to the stabilization of cell assemblies in the skin.(1) In the manufacturer's studies, Lactobacillus Ferment Lysate was found to inhibit the secretion of inflammatory cytokines. Overall, these results show that Lactobacillus Ferment Lysate has anti-inflammatory properties that can strengthen the skin's barrier function, limit transepidermal water loss, increase skin hydration and help restore the skin after external aggressions(2).
