Science
Mechanism of Action
The ingredient is a ferment product where Streptococcus zooepidemicus generates both hyaluronic acid (HA) and lactic acid. Hyaluronic acid is renowned for its exceptional water-binding capacity, contributing to superior skin hydration and viscoelasticity, which can also support the skin's natural healing processes. Lactic acid provides mild exfoliating action to promote cell turnover, alongside its humectant properties for added moisture. Concurrently, fermented wheat peptides introduce antioxidant activity, which helps to neutralize free radicals and protect skin integrity.

The Formula
Formulation
Stability
The optimal pH for Streptococcus zooepidemicus fermentation for hyaluronic acid production typically falls between pH 7 and 8. The hyaluronic acid component itself is polyanionic and highly water-soluble at typical cosmetic pH ranges, with a pKa of 3-4 for its carboxyl groups. However, the specific optimal pH range for the stability of the entire STREPTOCOCCUS ZOOEPIDEMICUS/WHEAT PEPTIDE FERMENT in a final cosmetic formulation is not explicitly documented.
Safety
Safety Profile
While there are no specific safety assessments for this combined ingredient, its individual components have known considerations. Hydrolyzed wheat proteins carry a risk of Type I hypersensitivity reactions if their average molecular weight exceeds 3500 Daltons; thus, cosmetic formulations must restrict peptides to this molecular weight or less. Additionally, Streptococcus zooepidemicus, being a bacterium, produces endotoxins that necessitate rigorous purification for cosmetic-grade hyaluronic acid to ensure product safety.

Verdict
While this ingredient theoretically offers promising hydrating, exfoliating, and antioxidant benefits, its 'insufficient data' CIR status and lack of specific clinical studies for the combined ferment necessitate further rigorous research for conclusive efficacy and safety.
