What Is Saccharomyces/Rice Bran Ferment Filtrate Extract?

Saccharomyces/Rice Bran Ferment Filtrate Extract is produced by fermenting rice bran using Saccharomyces yeast, then filtering the resulting liquid to create a concentrated extract. This fermentation process breaks down the rice bran's compounds into smaller, more bioavailable molecules that the skin can more readily absorb and utilise.

The extract functions primarily as a skin conditioner, helping to improve skin texture and maintain hydration. It typically contains amino acids, vitamins and polysaccharides from the rice bran, which are further modified by the fermentation process to enhance their skincare benefits.

How It Works

Fermentation breaks down complex compounds in rice bran into smaller peptides and amino acids that penetrate the skin more effectively than unfermented rice bran. These components can integrate into the skin's uppermost layers, where they help maintain hydration and support the skin's structural proteins.

The polysaccharides present in the extract form a light film on the skin's surface, which helps reduce transepidermal water loss and keeps the skin feeling smooth. The fermentation byproducts may also provide gentle conditioning benefits without heaviness.

Clinical Evidence & References

Clinical research specifically on this ingredient is limited. However, fermented botanical extracts generally show promise in supporting skin hydration and texture. The fermentation process is recognised in skincare science as a method to enhance the bioavailability of plant-derived compounds.

Rice bran itself has a longer history of use in skincare and contains beneficial compounds including inositol and gamma-oryzanol. The fermented version may offer improved skin penetration, though direct comparative studies are sparse. More targeted research would help clarify its specific efficacy in skincare formulations.

How to Use

This ingredient is typically incorporated into serums, essences and moisturisers at modest concentrations. It works well as part of a layered routine, particularly when applied to damp skin to maximise hydration benefits. It pairs well with other conditioning and hydrating ingredients and does not require special handling or timing considerations.

Safety & Precautions

Generally well-tolerated across skin types. Those with yeast sensitivities should be cautious, though topical application poses minimal risk compared to ingestion.
