Science
Mechanism of Action
The fermentation of Camellia japonica flowers with Saccharomyces yeast potentiates the release of key bioactive components, including amino acids, enzymes, antioxidants, and vitamins. These components work synergistically to provide essential nourishment, reduce inflammation, and stimulate the production of vital skin proteins like collagen and elastin. This process improves skin elasticity, refines texture, minimizes the visibility of fine lines and wrinkles, and fortifies the skin barrier through the upregulation of Claudin-1 expression, collectively protecting against environmental stressors and promoting cellular renewal.

Key findings
- 01 An in vitro study on Camellia japonica flower extract (not the specific ferment filtrate) demonstrated a significant pro-proliferative effect, enhancing Human Skin Fibroblast (HSF) cell viability by over 120%. This occurred at concentrations ranging from 0.0000224% to 0.025% (224–250 μg/mL). Direct clinical data for the Saccharomyces/Camellia japonica flower ferment filtrate is not available in the provided research.

Stability
A study examining Camellia japonica petal fermentation for wine production noted initial pH levels maintained at 5, which naturally decreased to 3.89–4.19 post-fermentation. This data indicates pH tolerance during the fermentation process itself, rather than establishing the optimal stability range for the final cosmetic filtrate.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Panel has issued an 'Insufficient Data Announcement' for yeast-derived ingredients as a collective group, requesting additional data points such as dermal sensitization, food use/GRAS status, or 28-day dermal toxicity for a comprehensive safety determination. While the broader category of 'Saccharomyces Ferment Filtrate' is generally considered safe, this specific combination falls within the group requiring further assessment. No specific SCCS opinion or FDA status for this exact ingredient was identified. However, Incidecoder rates its irritancy and comedogenicity as low.
