Aspergillus/Rice Ferment

Aspergillus/Rice Ferment is created by fermenting rice (often rice bran or red rice varieties) using Aspergillus, a microorganism commonly used in food and cosmetic production. During fermentation, the microorganism breaks down the rice's complex molecules into smaller, more bioavailable compounds including amino acids, peptides, and polysaccharides.In skincare formulations, this ingredient functions primarily as a humectant—a substance that draws moisture into the skin. The fermentation process enhances the concentration and effectiveness of rice's naturally occurring bioactive components,…

Fermentation fundamentally changes rice's chemical structure. The Aspergillus microorganism produces enzymes that decompose larger molecules into smaller peptides and amino acids. This process increases bioavailability—essentially making the beneficial compounds easier for skin cells to recognise and absorb.Once in the skin, these fermented compounds work as humectants by binding water molecules and holding them in the outer layers of the skin. Research also suggests they may trigger fibroblasts (the cells responsible for producing collagen and elastin) to increase synthesis of these struct…

Aspergillus/Rice Ferment is typically found in serums, essences, and hydrating creams. It pairs well with other humectants and hydrating ingredients. Use as directed by the product formulation—most commonly once or twice daily after cleansing and before other treatments. There is no need for special precautions beyond following the product instructions.

Aspergillus/Rice Ferment is generally well-tolerated and considered safe in cosmetic use. Those with known mould or fungal sensitivities should patch test first, though fermentation produces a stabilised ingredient rather than a live culture.
