Lactobacillus/Salix Alba Bark Ferment Filtrate

Lactobacillus/Salix Alba Bark Ferment Filtrate is a processed ingredient created through the fermentation of white willow bark using beneficial Lactobacillus bacteria. The fermentation process breaks down the plant material, releasing and concentrating bioactive compounds whilst producing a filtrate—a liquid extract free of solid residue.This ingredient functions as both an antioxidant and a skin conditioner. The white willow bark component traditionally contains salicylates and phenolic compounds, whilst the fermentation process may enhance their bioavailability and create additional benef…

The antioxidant action comes from phenolic compounds present in white willow bark that can neutralise reactive oxygen species. These molecules help prevent cellular damage from environmental aggressors like pollution and UV exposure.As a skin conditioner, the fermented filtrate forms a thin, protective layer on the skin surface that helps retain moisture and maintain skin elasticity. The fermentation process may also produce additional bioactive compounds—including organic acids and peptides—that further support skin condition and barrier function.

This ingredient is typically incorporated into serums, toners, and moisturisers where it can remain in contact with the skin. Use as directed by the product formulation—usually daily as part of your regular routine. Like all skincare ingredients, results develop gradually; consistent use over several weeks is more meaningful than short-term application.

Fermented botanical extracts are generally well-tolerated by most skin types. However, those sensitive to salicylates or with severe plant sensitivities should patch-test first, as white willow bark may trigger reactions in susceptible individuals.
