What Is Aspergillus … Ferment Filtrate?

This ingredient is a filtrate derived from the fermentation of rice, ginger root, and beneficial microorganisms including Aspergillus and Lactobacillus species. Fermentation breaks down the plant material into smaller, more bioavailable compounds whilst the microorganisms produce enzymes and metabolites that have conditioning properties.

The resulting filtrate functions primarily as a skin conditioning agent, helping to improve the feel and appearance of the skin surface through hydration and texture smoothing.

How It Works

Fermentation creates an environment where beneficial microorganisms produce enzymes—particularly proteases and amylases—that break down plant cell walls and create smaller molecular fragments. These fragments, along with metabolites produced during fermentation, can penetrate the outer layers of skin more easily than whole plant material.

The ingredient works primarily through hydration and occlusion; it draws moisture to the skin and helps seal it in, whilst the natural enzymes gently support the skin's natural shedding process without the friction of mechanical exfoliants.

Clinical Evidence & References

Whilst fermented ingredients have a long history of use in traditional skincare, published clinical evidence specifically for this multi-component ferment filtrate is limited. Individual components—ginger root and the enzymes produced by Aspergillus and Lactobacillus species—have been studied separately and show promise for skin conditioning and gentle exfoliation.

Evidence suggests that fermentation increases bioavailability of beneficial compounds compared to non-fermented plant extracts, but well-controlled studies comparing this specific filtrate against placebo or standard conditioning agents would strengthen the evidence base.

How to Use

This ingredient is typically found in serums, essences, and moisturisers. It can be used daily as part of your regular routine. If your product contains this as a key active, apply it to clean, damp skin before heavier moisturisers to maximise hydration benefits. It pairs well with other conditioning and hydrating ingredients.

Safety & Precautions

Generally well-tolerated across skin types. Those with sensitivity to fermented products, ginger, or fungi-derived ingredients should patch test first, as fermented ingredients can occasionally trigger sensitivity in reactive skin.
