Science
Mechanism of Action
The extract functions through a triple-action pathway: it inhibits tyrosinase activity to suppress melanin synthesis, utilizes a dense profile of flavonoids (quercetin and kaempferol) to neutralize oxidative stress, and downregulates pro-inflammatory cytokines like TNF-α and IL-6 to prevent micro-inflammation-induced aging.

Key findings
- 01 US Patent US9956151B2 (2018): Validated concentrations between 0.001% and 5% for the significant reduction of hyperpigmentation, wrinkles, and skin laxity.
- 02 Phenolic Compounds Research (2022): Isolated specific molecules showing inhibitory activity against alpha-glucosidase, supporting metabolic skin health.
- 03 Journal of Ayurvedic and Herbal Medicine (2023): In vitro data confirmed substantial inhibitory effects on LOX and XOD enzymes, marking it as a high-performance anti-inflammatory.
Transparency
Dusting Analysis
Due to patent claims suggesting efficacy at extremely low levels (0.001%), many formulations include it at 'label claim' concentrations that may provide antioxidant protection but fail to deliver visible brightening or anti-aging results.
The Formula
Formulation
Stability
The extract exhibits high thermal stability up to 120°C. However, its chemical integrity is compromised in environments with a pH below 3.0 or above 10.0.
Synergies
- L-Ascorbic Acid
- Niacinamide
- Tranexamic Acid
Conflicts
- Strong oxidizing agents
- Highly acidic exfoliating peels
Safety
Safety Profile
While not formally reviewed by the CIR, its long-standing history as 'Tiebaojin' in topical traditional medicine and low irritancy scores suggest a high safety margin.
