Bacillus … Ferment Filtrate

This ingredient is a fermented filtrate derived from rice bran and soybean, produced through the action of Bacillus microorganisms. Fermentation breaks down the plant material into smaller, more bioavailable compounds that can penetrate the skin more effectively than whole plant extracts.The resulting filtrate contains amino acids, peptides, and polysaccharides alongside natural antioxidants. In skincare formulations, it functions as both a skin conditioner and humectant, helping to improve skin texture and maintain hydration levels.

Fermentation creates smaller molecular compounds that can more easily cross the skin barrier compared to whole plant extracts. The amino acids and peptides act as humectants, binding water to the stratum corneum and helping to maintain hydration. The antioxidants present work by donating electrons to free radicals, stabilising them and preventing oxidative damage to skin cells.The conditioning effect comes from the emollient properties of the fermented botanical compounds, which sit on and within the skin surface to improve moisture retention and smoothness.

This ingredient is typically used as part of a complete formulation rather than applied in isolation. It works well alongside other hydrating and antioxidant ingredients. Apply as directed by your product instructions, whether as part of a serum, essence, moisturiser or treatment. Fermented extracts are often well-tolerated even by sensitive skin, though it is always advisable to patch test new products.

Generally well-tolerated and suitable for most skin types. Those with soy or fermented ingredient sensitivities should check the full ingredient list and perform a patch test first.
