Science
Mechanism of Action
The fermentation of Camellia sinensis seed oil by Pseudozyma epicola yeast substantially increases its content of free fatty acids, antioxidant vitamin E, and various polyphenols. This enriched fermentate works to enhance skin's hydration, reinforce the hydrolipid barrier, and support natural skin renewal processes. It also offers antioxidant defense and exhibits antiseptic, fungicidal, and bactericidal actions, aiding in the restoration of microbiome balance. Furthermore, the fermentate's altered composition improves skin absorption, leaves a less greasy feel, and provides enhanced emulsifying capabilities for improved cosmetic elegance.

This ingredient exhibits stability under normal storage conditions, requiring protection from direct sunlight and extreme temperatures. Its pH typically ranges from neutral to slightly acidic, dependent on the specific fermentation protocol. Its improved emulsifying capacity is a beneficial characteristic for various cosmetic formulations.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) concluded there was insufficient data to determine the safety of non-leaf-derived Camellia sinensis ingredients, as Camellia sinensis seed oil was assessed in a separate report. EWG advises that 'EWG VERIFIED products cannot contain this ingredient without adequate substantiation.' However, INCI Beauty rates this ingredient with 'No penalty' across all safety categories, suggesting a generally good safety profile in common cosmetic usage. Its irritancy potential is noted as low.
