Science
Mechanism of Action
Faex Extract works through a complex blend of peptides, amino acids, and vital B vitamins that hydrate and reactivate dermal functions. It acts as a protective barrier, shielding the skin from environmental stressors and pathogens, thereby supporting the natural skin barrier. Its sugar content aids in water retention, preventing dehydration and enhancing skin conditioning. As a biosurfactant, it assists in skin cleansing and addressing texture concerns. Rich in beta-glucan, vitamins, and flavonoids, it delivers antioxidant benefits, aiding in inflammation recovery and neutralizing free radicals. Furthermore, it can promote improved skin elasticity and a youthful appearance by mimicking collagen, and forms a protective film on the skin.

Dusting Analysis
Faex Extract exhibits a wide range of effective concentrations depending on the desired outcome. While antioxidant benefits are observed at very low percentages (e.g., ~0.03-0.05%), significant antibacterial effects, particularly against Cutibacterium acnes, require much higher concentrations (up to 40%). Formulators claiming strong antibacterial or anti-acne benefits at concentrations below 1% may be dusting, as robust efficacy against specific bacteria like C. acnes necessitates significantly higher inclusion rates.

Stability
Faex Extract is water-soluble with a characteristic acidic reaction pH of 6.6. No specific optimal pH range for stability in cosmetic formulations was identified in the provided data.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has issued an 'Insufficient Data Announcement' for yeast-derived ingredients, including Faex Extract, requesting further dermal sensitization and food use/GRAS data for cosmetic safety assessment. While yeast-related infections are primarily linked to live yeast strains, finished cosmetic products are not expected to contain viable yeast. The US FDA considers baker's yeast extract (from Saccharomyces cerevisiae) as Generally Recognized As Safe (GRAS) for food flavoring at concentrations not exceeding 5%.
