Science
Mechanism of Action
This intricate ingredient leverages the power of fermentation to enhance a synergy of botanicals and yeast on the skin. Saccharomyces ferment filtrate, rich in vital minerals, amino acids, beta-glucan, and vitamins, actively works to fortify the skin's natural barrier, significantly improve hydration, and foster a healthy skin microbiome. It functions as a potent antioxidant, neutralizing free radicals, and may stimulate cellular processes to support natural collagen and elastin synthesis. Apple fruit extract contributes humectant properties from its natural sugars, while its malic and gallic acids provide gentle exfoliation, promote skin brightening, and offer mild antibacterial effects. It is also a source of antioxidants like Vitamin C, phenolic compounds, and flavonoids, crucial for defending against environmental damage and promoting a youthful appearance. Melon fruit extract, abundant in vitamins A, C, E, flavonoids, and fructose, deeply nourishes skin cells, enhances moisture levels, provides soothing relief, and assists in mild cellular turnover by removing dead skin cells. The overall fermentation process significantly increases the skin's absorption of these active compounds, simultaneously enriching the blend with newly formed amino acids, peptides, and organic acids.

The Formula
Formulation
Stability
This ingredient maintains stability within a pH range of 3.5 to 6.5, with optimal performance typically observed at a slightly acidic pH of 4.5 to 5.5. To preserve its integrity, avoid temperatures exceeding 60°C. It should be incorporated into formulations during the cooling phase.
Conflicts
- Highly acidic or highly alkaline active ingredients that shift the product's pH outside the 3.5-6.5 optimal range.
- Robust preservative systems that might compromise the efficacy of its active or semi-active components. Formulators should opt for broad-spectrum preservatives effective within slightly acidic, water-based environments.
Safety
Safety Profile
The CIR Expert Panel has twice declared 'insufficient data' for 'Yeast-Derived Ingredients,' which encompasses Saccharomyces Ferment Filtrate, requesting further dermal sensitization data and information on food use/GRAS status for specific yeast species. While Saccharomyces cerevisiae (baker's yeast) is generally recognized as safe (GRAS) for food in certain contexts, this classification does not directly apply to the safety assessment of this specific cosmetic ingredient blend.
