Science
Mechanism of Action
This extract operates through a multi-pathway approach: it neutralizes reactive oxygen species (ROS) via EGCG polyphenols, inhibits Matrix Metalloproteinases (MMPs) to prevent collagen degradation, and modulates sebum production by influencing the AMPK/mTOR cellular signaling pathways. Its high L-theanine concentration specifically targets inflammatory cytokines to dampen the skin's stress response.

Clinical Evidence
High confidence1%
Key findings
- 01 Topical 2% concentration demonstrated a significant reduction in sebum secretion and clinical improvement in acne vulgaris (JDD).
- 02 Concentrations between 0.1% and 2.0% significantly inhibited pro-inflammatory cytokine production, mitigating UV-induced oxidative damage.
- 03 Formulations at 0.0975% have been clinically utilized to provide immediate soothing relief to fatigued or dull skin.

Dusting Analysis
While this ingredient appears frequently in 'natural' marketing, it is often included at levels below 0.1% solely for label claims. For therapeutic sebum regulation and collagen protection, a concentration of 1-2% is required.
The Formula
Formulation
Stability
Highly prone to oxidation when exposed to light, heat, or oxygen, which can cause the formula to discolor. It remains most stable in slightly acidic environments.
Synergies
- Vitamin C
- Hyaluronic Acid
- Niacinamide
Conflicts
- Iron salts
- Strong oxidizing agents
- High pH environments (>7.0)
Safety
Safety Profile
While leaf-derived extracts are confirmed safe up to 0.86% in leave-on products, the CIR lacks specific characterization data for the sprout variant; however, no significant adverse effects are noted in current dermatological literature.
