Science
Mechanism of Action
This ferment filtrate delivers essential nutrients, antioxidants, and beneficial metabolites to the skin. It works to mitigate inflammation, stimulate the skin's intrinsic collagen synthesis, and enhance elasticity. The fermentation process yields valuable polysaccharides, peptides, amino acids, minerals, and vitamins that nourish and hydrate the skin, strengthening its natural barrier. Furthermore, it may contain heat shock proteins (HSPs) which bolster cellular resilience against environmental stressors, alongside soothing compounds that can alleviate redness and irritation, making it suitable for sensitive skin.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that 'Saccharomyces Ferment Filtrate' is safe in cosmetics, particularly when derived from yeast species affirmed for both dermal sensitization and food use. The US FDA recognizes *Saccharomyces cerevisiae*, a core component of this fermentation, as Generally Recognized As Safe (GRAS) for food applications up to 5% and as a multipurpose additive. Specific maximum concentrations for this exact ingredient by CIR are not specified, although incidental ingestion of the related 'Saccharomyces Ferment Filtrate' in certain products has been reported up to 0.065%.
