Science
Mechanism of Action
This ingredient functions as a robust skin conditioning agent, improving the appearance of dry or damaged skin by reducing flaking and restoring suppleness. It stimulates hyaluronic acid synthesis in the skin via Glycokines, bolsters the skin's natural moisturizing factor, and strengthens the epidermal barrier. Furthermore, it exhibits antioxidant properties against free radicals, provides anti-aging benefits by addressing collagen breakdown, and offers soothing effects that calm inflammation. Its essential amino acids and peptides can target melanocytes for brighter skin, while beta-glucans stimulate Langerhans cells and promote collagen production.

Stability
Hydrolyzed yeast components generally maintain stability across a broad pH range. However, their foaming capacity is poor between pH 3.0 and 9.0, with emulsifying activities slightly higher at near acidic pH.
Synergies
- Other water-binding agents (to enhance hydration and barrier function)
- Ingredients within specific complexes (e.g., Optim Hyal, to stimulate hyaluronic acid synthesis)
Safety
Safety Profile
The CIR Expert Panel concluded that Hydrolyzed Yeast and its extracts are safe for cosmetic use under current practices, provided they are derived from appropriate yeast species. The FDA has affirmed Saccharomyces cerevisiae (a common source) as 'generally recognized as safe (GRAS)' for certain food uses up to 5%. It is considered safe for topical application, with adverse reactions being uncommon, though patch testing is recommended for individual sensitivities.
