Science
Mechanism of Action
It operates as a biopolymeric humectant, creating a breathable mesh on the skin's surface that traps water molecules within the stratum corneum to halt trans-epidermal water loss. Beyond hydration, it serves as a secondary antioxidant by neutralizing reactive oxygen species and offers physical photoprotection while modulating melanin production through tyrosinase inhibition.

Key findings
- 01 Promotion of fibroblast proliferation for wound healing and anti-aging at 0.01-0.04%.
- 02 Dose-dependent tyrosinase inhibition for brightening at 0.025-0.1%.
- 03 Moisture retention capabilities exceeding hyaluronic acid in arid conditions at concentrations up to 2.0%.

Dusting Analysis
Because it is a 'green tea' derivative, brands often include it at trace levels (0.01% or less) for marketing. However, moisture-retention and significant brightening efficacy require concentrations of at least 0.1% to 1.0%.
The Formula
Formulation
Stability
Highly stable at room temperature in aqueous solutions; however, the molecular structure may undergo hydrolysis if exposed to heat exceeding 80°C or extreme pH environments.
Synergies
- Hyaluronic Acid
- Glycerin
