Science
Mechanism of Action
The complex functions through high-density natural tannins that cross-link with epidermal surface proteins, resulting in a temporary micro-tightening effect on pore walls. It simultaneously downregulates oil production by inhibiting the enzyme 5-alpha reductase, while Resveratrol from Polygonum Cuspidatum neutralizes oxidative stress.

Key findings
- 01 In vivo testing on 20 subjects at 2% concentration showed a 25.3% reduction in visible pore diameter and a 32.1% decrease in oil secretion over 28 days.
- 02 In vitro studies confirm significant 5-alpha reductase inhibition, indicating sustained sebum regulation and anti-inflammatory properties.

Dusting Analysis
Because of its complex INCI name, brands often include this at trace levels for marketing claims; however, clinical data proves that a minimum of 1-2% is required to achieve measurable pore reduction and oil control.
The Formula
Formulation
Stability
Aqueous stability is high within slightly acidic ranges. It is imperative to keep formulation temperatures below 60°C to preserve the integrity of the heat-sensitive polyphenols.
Synergies
- Niacinamide (complementary sebum regulation)
- Hyaluronic acid (hydration balance)
- Salicylic Acid (enhanced pore clearing)
Conflicts
- Iron salts (causes dark chelation discoloration)
- Strong oxidizing agents
- Alkaline environments (pH > 8.0)
Safety
Safety Profile
While the complex is a blended entity, its primary botanical components like Camellia Sinensis and Safflower are extensively reviewed and documented as safe in cosmetic applications.
