What Is Bacillus … Ferment Filtrate?

This ingredient is a ferment filtrate derived from Artemisia vulgaris (mugwort) that has been processed using Bacillus fermentation. Fermentation breaks down plant material into smaller, potentially more bioavailable compounds, which are then filtered to create a liquid extract.

The resulting ingredient functions primarily as a skin conditioner, helping to support the skin's hydration and overall condition. Fermented plant extracts are used in skincare for their potential to deliver beneficial compounds from the original botanical source.

How It Works

Fermentation alters the structure of plant compounds, potentially making them smaller and easier for the skin to absorb. This process can also generate new beneficial molecules produced by the Bacillus bacteria during fermentation.

Once applied, the extract works as a skin conditioner by helping to maintain hydration at the skin's surface and supporting the skin barrier's overall health and appearance.

Clinical Evidence & References

Published clinical data specifically on this ferment filtrate is limited. However, mugwort (Artemisia vulgaris) has been studied for its antioxidant and anti-inflammatory properties in traditional use, and fermentation as a processing method is recognised in cosmetic science as a way to preserve and potentially enhance bioactive plant compounds.

More targeted research would be needed to establish specific efficacy claims for this particular extract in skincare applications.

How to Use

This ingredient is typically used as part of a complete skincare routine. It works well in serums, toners, and essences where it can be applied to clean skin before heavier creams or oils. There are no known restrictions on combining it with other skincare ingredients, though as with any new product, patch testing is sensible if you have sensitive skin.

Safety & Precautions

Generally considered safe for topical use in cosmetics. Those with known sensitivity to Asteraceae plants (daisy family) should exercise caution, as mugwort belongs to this family.
