Leuconostoc Ferment Lysate Filtrate

Leuconostoc Ferment Lysate Filtrate is a fermentation-derived ingredient produced by breaking down Leuconostoc bacteria and filtering the resulting liquid. Fermentation processes can concentrate beneficial compounds and create smaller molecular components that may penetrate or condition skin more effectively than the raw ingredient alone.In skincare formulations, this ingredient functions primarily as a humectant and skin conditioning agent, helping to soften the skin surface and support hydration. It's often used in moisturisers, essences, and treatment serums where a gentle, nourishing ef…

Fermented ingredients work by delivering amino acids, peptides, and other small molecular compounds that the fermentation process breaks down from the original bacterial source. These components can absorb into the skin's upper layers and hydrate the stratum corneum (the outermost skin layer).The filtration step removes bacterial cells themselves, leaving behind a liquid rich in metabolites and breakdown products. This conditioning effect is typically gentle and well-tolerated, making fermented filtrates a popular choice in formulations targeting sensitive or compromised skin.

This ingredient is typically used in leave-on formulations such as serums, essences, toners, and moisturisers. Apply to clean skin before heavier creams or oils to allow absorption. It can be used daily as part of a regular skincare routine and layers well with other hydrating or conditioning ingredients.

Generally well-tolerated across skin types. As with any fermented ingredient, those with sensitivity to fermentation-derived products should patch-test first.
