Science
Mechanism of Action
This extract operates through a triple-action pathway: it inhibits tyrosinase to modulate melanin production, suppresses MMP-1 enzymes to prevent collagen degradation, and actively stimulates Type 1 procollagen synthesis. Additionally, its high concentration of caffeoylquinic acid derivatives provides robust antioxidant protection against oxidative stress-induced cellular damage.
Research
Clinical Evidence
Medium confidence2%
Key findings
- 01 A 28-day human clinical trial demonstrated that a 2% concentration significantly enhanced skin translucency and tone uniformity through thioredoxin-mediated detoxification.
- 02 Ex vivo patent modeling confirmed significant reduction in melanin biosynthesis alongside a measurable increase in dermal elasticity markers.

Dusting Analysis
While many formulations include this extract at concentrations below 0.5% for marketing claims, clinical data suggests that a 2.0% threshold is necessary to achieve significant improvements in skin brightness and detoxification.
