SACCHAROMYCES/SOY PROTEIN FERMENT.

Valuable / SKIN CONDITIONING

Saccharomyces/Soy Protein Ferment is an advanced bio-fermented complex derived from Saccharomyces yeast and soy protein. This innovative ingredient delivers robust antioxidant protection, deep hydration, and supports cellular regeneration to enhance skin elasticity and radiance. Its calming properties further contribute to reduced skin sensitivity and irritation.

Science

Mechanism of Action

This ferment acts as a potent skin conditioning agent through a dual-action mechanism. The Saccharomyces component effectively neutralizes free radicals, while supplying vital polysaccharides and peptides that significantly boost skin moisture retention and stimulate cellular repair. Simultaneously, the soy protein fraction introduces phytoestrogens and cryptic peptides, which are shown to support wound healing by enhancing dermal extracellular matrix synthesis and encouraging re-epithelialization. The inherent anti-bacterial, anti-inflammatory, and antioxidant benefits of soy protein are amplified by the fermentation process, which generates highly bioavailable bioactive peptides and smaller molecular compounds, optimizing their penetration and efficacy within deeper skin layers.

Stability

The fermentation process for Saccharomyces cerevisiae typically thrives within a pH range of 4.0 to 6.0. Soybean fermentation, especially for protein enrichment, is optimized around pH 3.0, with observed finished product pH values ranging from 4.69 to 6.51. This suggests the ingredient is stable and active across a broad mildly acidic to slightly acidic pH spectrum, crucial for maintaining its beneficial properties in cosmetic formulations.

Safety

Safety Profile

CIR Status
Insufficient data
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) has classified this specific combined ingredient as having 'insufficient data' for a full safety assessment, though some individual yeast-derived components are deemed safe. Saccharomyces cerevisiae, a component, is generally recognized as safe (GRAS) by the FDA for food use up to 5%. No specific SCCS status is available, and Paula's Choice has not yet rated it. However, INCI Beauty indicates 'No penalty' across all safety categories, and its irritancy profile is noted as low.
