Science
Mechanism of Action
This ingredient functions as a potent tyrosinase inhibitor, effectively disrupting the melanogenesis process to reduce hyperpigmentation. At a molecular level, it modulates the Yin-Yang-1 (YY1) protein to support epidermal maturation, while its Atractylenolide compounds (I, II, and III) suppress NF-κB/Caspase-1 activation to mitigate inflammatory responses. Additionally, its polysaccharide content acts as a humectant to bolster surface hydration.
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Demonstrated an 84.6% tyrosinase inhibition rate at a 0.5% concentration in whitening assays.
- 02 Significant DPPH free radical scavenging observed at concentrations as low as 0.2% (2000 μg/mL).
- 03 Formulations reaching 6.18% in complex herbal serums show verified efficacy in skin barrier repair and antioxidant protection.
Transparency
Dusting Analysis
While it provides basic soothing benefits at 0.1%, clinical brightening effects require concentrations closer to 0.5%. Levels below 0.1% are typically included for marketing claims rather than physiological change.
The Formula
Formulation
Stability
Contains a hybrid of water-soluble polysaccharides and oil-soluble sesquiterpenes. It is sensitive to extreme thermal shifts and degrades in environments outside the physiological pH range.
Synergies
- Niacinamide
- Vitamin C derivatives
- Herbal extracts like Paeonia Lactiflora (Sanbai Powder context)
Conflicts
- Strong oxidizing agents
- Highly acidic formulations (pH < 4.0)
Safety
Safety Profile
Recognized as safe by EU COSMILE standards for use as a skin protectant and abrasive. While oral use in TCM is historically extensive, topical CIR evaluation is currently pending.
