Performance & Formulation Insights for FermentEx Lactoba

How Lactobacillus Ferment Works

FermentEx Lactoba is a postbiotic ingredient, containing the beneficial metabolites and cellular fractions produced by Lactobacillus during fermentation. Unlike live probiotics, postbiotics are non-living, offering enhanced stability and safety for topical use. These bioactive compounds work harmoniously with the skin’s natural ecosystem to support a balanced microbiome. By favoring beneficial microflora, this ferment helps crowd out harmful bacteria, reduce visible irritation, and fortify the skin’s defensive barrier—resulting in calmer, more resilient skin better able to withstand environmental stressors.

Formulation Guidelines

FermentEx Lactoba is a clear, water-soluble liquid that integrates easily into serums, emulsions, toners, and cleansers. For optimal stability, add it to the water phase or during the cool-down stage at temperatures below 40 °C (104 °F). It is stable within a typical cosmetic pH range of 4.0–7.0 and is compatible with common actives including hyaluronic acid, niacinamide, and botanical extracts. While Lactobacillus Ferment exhibits some antimicrobial activity, it is not a standalone broad-spectrum preservative and must be paired with an effective preservation system.
