Aspergillus … Ferment Filtrate

This ingredient is a ferment filtrate — a liquid extract created by fermenting pumpkin seed with beneficial fungi (Aspergillus and Saccharomyces species). Fermentation breaks down the plant material into smaller, more bioavailable compounds, which can include amino acids, polysaccharides, and other organic molecules.In skincare, it functions primarily as a skin conditioner, helping to support hydration and maintain the skin's texture. The fermentation process is thought to enhance the bioactivity of the raw ingredient, making it more effective in formulation than unfermented pumpkin seed al…

Fermentation creates a more permeable form of the plant material, allowing active compounds to penetrate the skin more readily. The resulting filtrate can deposit humectants and hydrating polymers on the skin surface, which help bind water and prevent transepidermal water loss.The fermentation process also produces secondary metabolites — substances the fungi generate during fermentation — which may have additional soothing or antioxidant effects, though the extent of these varies depending on fermentation conditions and the final product.

This ingredient is typically used as part of a broader formulation rather than in isolation. Apply products containing it to clean skin, morning and evening, as part of your regular routine. It works well alongside other hydrating or conditioning ingredients and does not require special preparation or timing.

Generally well-tolerated across skin types. Those with known sensitivities to fungi, pumpkin or fermented ingredients should patch-test first.
