Science
Mechanism of Action
Functioning as a potent postbiotic, this ferment filtrate delivers a diverse array of bioactive compounds that profoundly influence skin physiology. It actively mediates skin inflammation, aids in managing various skin conditions, and helps prevent allergic contact dermatitis. By selectively decolonizing skin pathogens and balancing the skin's native microbiome, it fortifies the epidermal barrier, enhances moisture absorption, and helps mitigate visible signs of aging. Furthermore, its demonstrated antimicrobial properties against harmful bacteria and fungi, combined with its natural antioxidant capabilities, shield the skin from free radical damage and soothe irritation by reducing redness. The ingredient also assists in optimizing skin's pH balance, and specific postbiotics within the filtrate, such as lactic acid, can act as tyrosinase-inhibitors, offering potential benefits for skin depigmentation.

Dusting Analysis
Given its complex profile as a postbiotic rich in bioactive compounds, this ingredient is valued for its specific mechanistic benefits rather than being used at sub-efficacious concentrations.
The Formula
Formulation
Stability
The fermentation process inherently creates an acidic environment, typically within a pH range of 3.0 to 5.0. This precise acidity is crucial for the optimal activity of beneficial enzymes, such as glutamic acid decarboxylase (GAD), and ensures the stability and efficacy of its key bioactive compounds.
