Science
Mechanism of Action
Operates through a four-tiered biological pathway: first, it inhibits melanin synthesis by downregulating the Mitf and tyrosinase pathways; second, it blocks pro-inflammatory signals (NF-κB and MAPK); third, it reinforces the skin’s structural integrity to boost moisture retention; and fourth, it utilizes sesquiterpenoids like atractylenolides to neutralize oxidative stress.
Research
Clinical Evidence
High confidence2%
Key findings
- 01 Demonstrated significant reduction in melanin production and IL-17 mediated inflammation at 1.0%–5.0% concentrations.
- 02 In-vivo trials at 2.0% confirmed visible improvements in microcirculation, redness reduction, and overall skin radiance.

Dusting Analysis
To achieve measurable brightening and anti-inflammatory results, concentrations should meet or exceed 1.0%. Formulations using this extract at levels below 0.5% are likely utilizing it for label-marketing rather than functional efficacy.
The Formula
Formulation
Stability
Maintains high stability in hydro-glycolic bases. It is thermolabile and must be incorporated during the cooling phase of production (below 40°C) to prevent the degradation of volatile sesquiterpenoids.
Synergies
