Science
Mechanism of Action
The extract operates through a multi-faceted biological pathway: it suppresses melanin synthesis by inhibiting tyrosinase activity while simultaneously upregulating the mRNA expression of Thymosin beta-4 (Tβ4). This stimulation of dermal fibroblasts accelerates the production of essential extracellular matrix proteins, including collagen, elastin, and fibrillin, to improve skin density.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Upregulation of Thymosin beta-4 (Tβ4) in dermal fibroblasts leading to enhanced collagen and elastin synthesis (US Patent 9,114,089 B2).
- 02 In vitro tyrosinase inhibition studies showing IC50 values between 44.62-60.20 µg/mL for potent depigmenting effects.
Transparency
Dusting Analysis
Because clinical efficacy for anti-aging and brightening is documented at concentrations as low as 0.1%, many formulations include it at 'label claim' levels (below 0.05%) which may fail to trigger the Tβ4 upregulation required for structural benefits.
The Formula
Formulation
Stability
The extract is stable in standard emulsions but susceptible to color shifts or degradation in extreme pH environments (below 3.0 or above 8.0) due to its phenolic content.
