Science
Mechanism of Action
The extract operates through a multifaceted approach, supplying the skin with vital components such as vitamins (e.g., B, C), amino acids, and beta-glucan. Its primary actions include robust antioxidant protection, aiding in cellular nourishment, and stimulating collagen synthesis to improve skin elasticity. It contributes to strengthening the skin's natural barrier, thereby minimizing transepidermal water loss and offering some protection against environmental stressors. Additionally, its anti-inflammatory properties can soothe irritation. The presence of heat shock proteins (HSPs) may also contribute to cellular repair and anti-aging benefits, while its humectant nature boosts moisture retention.

Stability
This ingredient exhibits water solubility. While the optimal pH for the stability of the final cosmetic ingredient is not definitively established, studies on the wheat germ fermentation process with Saccharomyces cerevisiae suggest peak total phenol content around pH 6.0.
Safety
Safety Profile
The CIR Expert Panel has indicated 'Insufficient Data' for yeast-derived ingredients (including Saccharomyces cerevisiae, a component of this ferment), citing a need for confirmatory dermal sensitization data for cosmetic applications. Although the FDA generally recognizes Saccharomyces cerevisiae as safe (GRAS) for food use up to 5%, some individuals, particularly those with sensitive skin, may experience localized reactions such as itching or irritation.

Verdict
This ferment extract shows promise for skin hydration, barrier support, and anti-aging benefits due to its rich nutrient profile, but comprehensive safety data for cosmetic use, including sensitization and specific concentrations, remains insufficient.
