Science
Mechanism of Action
The extract operates through a multi-pathway approach: it optimizes the skin's antioxidant profile by stimulating Superoxide Dismutase (SOD) activity and scavenging free radicals. On a structural level, it triggers the synthesis of endogenous hyaluronic acid and modulates collagen metabolism to maintain dermal density, while its unique iridoid and glycoside content offers natural UV-absorbing properties and inhibits tyrosinase to regulate melanin production.

Key findings
- 01 Demonstrated significant DPPH radical scavenging activity in vitro, confirming its status as a high-performance antioxidant.
- 02 Observed measurable improvements in hyaluronic acid production and biomarkers related to moisture retention and collagen metabolism.

Dusting Analysis
Due to its potency and cost, this extract is frequently included in 'label-only' concentrations. Formulations containing less than 0.1% may provide basic antioxidant support but likely fail to trigger the collagen-metabolism and hyaluronic acid stimulation benefits observed in higher-concentration in vitro studies.
The Formula
Formulation
Stability
The extract exhibits excellent long-term stability (up to 48 months at standard conditions) when maintained in an acidic environment below pH 8.5.
Synergies
- Vitamin C
- Hyaluronic Acid
- Ferulic Acid
Conflicts
- High-alkalinity formulations (pH > 8.5)
Safety
Safety Profile
While EFSA raised concerns regarding high-dose oral ingestion (novel food status), topical application has been validated via human patch testing to be non-stimulating and safe for cosmetic use.
