Science
Mechanism of Action
The ingredient functions by delivering metabolites derived from the Saccharomyces yeast fermentation of apple fruit and sucrose. This biotransformation process breaks down larger molecules into smaller, more skin-accessible compounds such as amino acids, peptides, organic acids, and antioxidants. These components are understood to enhance skin conditioning, contribute to hydration, and provide antioxidant support. The hydrolyzed conchiolin protein further enriches the filtrate with amino acids and peptides, specifically aiding in skin moisturization and reinforcing barrier integrity.

Stability
While direct stability data for this precise blend are not available, fermentation processes involving apple and yeast commonly yield acidic conditions. For example, fermented apple juices can see pH values drop from approximately 5.55 to 3.75, and apple cider raw material typically ranges from pH 3.0-3.8. This suggests the ingredient may be stable or perform optimally in a moderately acidic environment, though the specific optimal pH range for the final filtrate is unconfirmed.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed 'Yeast-Derived Ingredients' and 'Apple-derived Ingredients' as broader groups. Saccharomyces cerevisiae, a common yeast species, holds FDA Generally Recognized As Safe (GRAS) status for food use as a flavoring agent and adjuvant at levels not exceeding 5%. However, this specific complex blend, SACCHAROMYCES/APPLE FRUIT/HYDROLYZED CONCHIOLIN PROTEIN/SUCROSE FERMENT FILTRATE, has not undergone individual review by the CIR Expert Panel or the SCCS for cosmetic applications, and a specific FDA cosmetic status or maximum concentration is not identified in current research.
