Science
Mechanism of Action
This ingredient enhances skin health by strengthening the natural barrier, significantly reducing transepidermal water loss. Its complex sugars, including oligosaccharides and polysaccharides, act as potent humectants, while skin-friendly lipids boost barrier resilience. Antioxidant beta-glucans and converted yeast sugars protect against free radical damage, supporting cellular recovery and potentially stimulating collagen synthesis for anti-aging effects. Furthermore, it supplies essential amino acids and peptides that nourish cell growth, activate metabolic pathways, and target melanocytes for skin brightening, while also offering soothing and anti-inflammatory benefits.

Stability
Yeast protein hydrolysates exhibit high solubility at acidic pH 2 and alkaline pH 12, with minimal solubility around the isoelectric point of pH 4-6. Enzymatic treatment significantly enhances protein solubility across various pH ranges, with solubility primarily influenced by molecular weight, amino acid composition, average charge, pH, and ionic strength.
Safety
Safety Profile
The CIR Expert Panel considers Hydrolyzed Yeast Protein safe for topical cosmetic application. Its parent yeast, Saccharomyces cerevisiae, is affirmed by the U.S. FDA as Generally Recognized As Safe (GRAS) up to 5% in food. While adverse reactions are uncommon, patch testing is advisable before broad application. Data regarding topical use during pregnancy or breastfeeding is limited.
