Science
Mechanism of Action
This potent blend primarily operates as an antioxidant, effectively preventing undesirable oxidation reactions that can lead to ingredient degradation and compromise cellular integrity in the skin. The Saccharomyces ferment fraction delivers a rich supply of essential minerals, amino acids, beta-glucan, and vitamins, which collectively contribute to significant skin moisturization, soothing effects, and possess potential for skin brightening and the mitigation of wrinkle appearance. Concurrently, Pichia kudriavzevii supports skin health by degrading organic acids, releasing beneficial hydrolases, and exhibiting probiotic properties.

As a ferment extract filtrate, this ingredient is typically a liquid or semi-liquid, rendering dusting concerns irrelevant in formulation.
The Formula
Formulation
Stability
The Pichia kudriavzevii organism, integral to the fermentation, exhibits notable robustness with high tolerance to extreme pH levels, elevated temperatures, and hyperosmotic stress. While specific optimal pH ranges for the final cosmetic filtrate are not explicitly defined, a reference Saccharomyces cerevisiae extract has been reported to maintain stability within a pH range of 4.0-5.0. Given its nature, this ferment extract filtrate is generally anticipated to be water-soluble.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has conducted safety assessments for a broad category of 'Yeast-derived ingredients,' encompassing various Pichia and Saccharomyces species. However, this specific combined ferment extract filtrate has not undergone an individual review by CIR or SCCS. Nevertheless, component ingredients like Saccharomyces cerevisiae are generally recognized as safe (GRAS) by the FDA for food applications, typically at levels not exceeding 5%, and grape-derived ingredients are approved food additives. Pichia kudriavzevii itself is commonly found in food fermentation processes, with some strains having been evaluated for probiotic properties. Specific maximum dermal concentrations or comprehensive sensitization data for this combined ingredient are not currently available.
