Science
Mechanism of Action
This ingredient operates through a multi-pathway approach: polyphenols and catechins neutralize oxidative species to prevent DNA damage, while water-soluble polysaccharides (TFP-1) act as humectants to lock in moisture. Furthermore, floratheasaponins provide conditioning benefits and possess natural antimicrobial properties that support a balanced skin microbiome.
Research
Clinical Evidence
High confidence5%
Key findings
- 01 A 12-week clinical trial demonstrated that a 5% concentration significantly diminished periorbital 'crow's feet' wrinkles and enhanced skin elasticity.
- 02 In vitro testing showed a 71.5% antifungal efficacy at 6.4 mg/mL, highlighting its role in maintaining skin purity.
- 03 Single-blind trials confirmed significant anti-sebum activity when applied in toner formulations, making it effective for oil regulation.

Dusting Analysis
Because it is an 'aqueous extract,' brands frequently use it at very low percentages (under 1%) simply to claim 'Green Tea' on the label. To achieve the clinically validated anti-aging and sebum-regulating benefits, it should be used at 5% or higher, or as a primary base.
The Formula
Formulation
Stability
Highly sensitive to oxidation and light; catechins can degrade and cause browning if exposed to air or alkaline environments. Best stored in opaque packaging.
Synergies
- L-Ascorbic Acid
- Hyaluronic Acid
- Niacinamide
Conflicts
- Iron salts
- Strong oxidizing agents
- Highly alkaline ingredients (pH > 7.0)
Safety
Safety Profile
While the CIR has flagged flower-specific data as insufficient compared to leaf extracts, current clinical use shows no adverse effects at functional levels up to 5%, and leaf-derived waters are safely used up to 30%.
