Aspergillus … Ferment Filtrate

Aspergillus/Rice/Rice Bran Ferment Filtrate is a liquid extract produced by fermenting rice or rice bran using Aspergillus fungi. During fermentation, the fungus breaks down rice components into smaller, more bioavailable molecules. The resulting filtrate is a conditioning ingredient that sits between active treatment components and emollients in formulation.In skincare products, it functions primarily as a skin conditioner and emollient, helping to maintain moisture and create a smooth skin feel. It's included in formulations to support the skin barrier and improve texture.

Fermentation breaks rice proteins and carbohydrates into smaller peptides and sugars that can penetrate or condition the outer skin layers more effectively than whole rice particles. These molecules act as humectants (drawing water to the skin) and emollients (smoothing the surface), helping to maintain hydration and improve skin feel.The fermentation process also may produce naturally occurring compounds that support skin comfort, though the specific active molecules vary depending on fermentation method and duration.

This ingredient is typically used as part of a complete formulation rather than in isolation. It works well in serums, essences, toners, and creams where it blends smoothly with other hydrating or conditioning agents. Use it as part of your regular routine—there is no need to cycle it or limit frequency, as it is gentle and non-irritating for most people.

Aspergillus/Rice/Rice Bran Ferment Filtrate is generally well-tolerated. Those with known rice allergies should patch-test first, though topical application carries lower risk than ingestion.
