Science
Mechanism of Action
The fermentation process utilizes Aspergillus species to break down bulky green tea catechins into smaller, high-affinity polyphenol derivatives known as Teadenols A and B. These molecules penetrate the epidermal layers more effectively to inhibit tyrosinase (preventing hyperpigmentation) and elastase (preserving skin elasticity), while simultaneously neutralizing oxidative stress induced by UV exposure.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 Comparative studies show significant improvements in wrinkle depth and skin luminosity at concentrations between 1-3% compared to non-fermented counterparts.
- 02 Bioactive Teadenol A exhibits anti-acne and barrier-strengthening properties at concentrations as low as 0.001-0.1%.
Transparency
Dusting Analysis
While very low concentrations (below 0.1%) provide some antioxidant benefits from Teadenols, the significant anti-aging and brightening effects verified in clinical catalogs require a minimum of 1%. Formulas listing this ingredient at the bottom of the INCI list may only be utilizing it for claim purposes.
The Formula
Formulation
Stability
Highly stable in aqueous solutions; the spray-dried powder form is easily dispersible. Should be kept in UV-protected packaging to prevent the oxidation of active phenolic compounds.
Synergies
- Niacinamide
- Hyaluronic Acid
- Vitamin C
Conflicts
- Strong oxidizing agents
- Highly alkaline environments (pH > 8.0)
Safety
Safety Profile
Classified under the broader safe profile of Camellia sinensis leaf derivatives. It is well-tolerated when formulated to be non-sensitizing.
