Aspergillus … Ferment Filtrate

Aspergillus/Saccharomyces/Rice Ferment Filtrate is a liquid derived from the fermentation of rice using beneficial fungi and yeast. During fermentation, these microorganisms break down rice components into smaller, more bioavailable molecules—a process that can enhance the ingredient's functionality in skincare formulations.In cosmetics, this ferment filtrate primarily functions as a humectant and skin conditioner. Humectants draw moisture into the skin, whilst conditioning agents help improve skin texture and appearance.

The fermentation process breaks down complex rice carbohydrates and proteins into smaller molecules that the skin can more readily absorb or benefit from. This makes the ingredient potentially more effective than unfermented rice extracts.As a humectant, this filtrate works by drawing water from the air and deeper skin layers to the outer surface, helping to plump and hydrate the stratum corneum (the skin's outer layer).

This ingredient is typically found in serums, essences, and toners where it can be applied to clean skin before heavier creams or oils. As a humectant, it works best when applied to damp skin to lock in hydration. It layers well with most other skincare ingredients and can be used once or twice daily depending on your skin's needs.

Generally considered safe and well-tolerated across skin types. Those with fermentation sensitivities or yeast-related concerns should patch test first.
