Lactobacillus Ferment Lysate Filtrate

Lactobacillus Ferment Lysate Filtrate is a processed ingredient derived from Lactobacillus bacteria that have been fermented and then broken down (lysed) to create a filtrate. This filtrate contains the cellular components and metabolites produced during fermentation, which are then incorporated into skincare formulations.The ingredient functions primarily as a skin conditioning agent, working to improve the skin's texture, hydration levels, and overall appearance. Because it comes from a fermented source, it may contain peptides, amino acids, and other bioactive compounds that can support …

When bacteria are fermented, they produce metabolites and break down into smaller molecular components. These fragments—including amino acids, peptides, and other organic compounds—are collected in the filtrate and added to skincare products.Once applied to skin, these components are thought to absorb into the stratum corneum (the outermost layer) where they can help bind moisture, support the skin barrier, and provide conditioning effects. The exact mechanism depends on which specific compounds are present in the filtrate.

This ingredient is typically used in serums, moisturisers, and essences at concentrations determined by the formulator. Apply to clean skin as part of your regular routine. It works well in both AM and PM regimens and can be layered with other skincare actives, though patch testing is advisable if your skin is reactive.

Lactobacillus Ferment Lysate Filtrate is generally well-tolerated and considered safe for topical use. Those with severe sensitivity to fermented ingredients should patch test first.
