Science
Mechanism of Action
This extract operates through a four-fold biological pathway: it inhibits pro-inflammatory 'pyroptosis' (programmed cell death) by suppressing MAPK and NF-κB signaling, neutralizes nitric oxide and reactive oxygen species via its flavonoid content, provides antimicrobial defense through specialized peptides called shepherins, and limits melanin synthesis by interfering with tyrosinase activity.

Key findings
- 01 In vivo testing of a 2.0% active complex demonstrated significant clinical reductions in facial redness and capillary blood flow through pyroptosis pathway targeting.
- 02 In vitro analysis at 100.0 µg/mL showed a 65% inhibition of PGE2 and marked suppression of inflammatory cytokines TNF-α and IL-6.
- 03 Concentration-dependent radical scavenging reached an EC25 of 0.2 µg/mL against Nitric Oxide radicals.
Transparency
Dusting Analysis
While potent at micro-levels for antioxidant protection, clinical results for redness reduction and anti-inflammatory relief are typically tied to concentrations near 2.0%. Formulations using it at 'label-only' concentrations (<0.1%) likely fail to trigger the pyroptosis-inhibiting benefits.
The Formula
Formulation
Stability
The extract is thermostable up to 60°C; however, encapsulation in liposomes is recommended to enhance the penetration of its sensitive flavonoid profile.
Synergies
- Vitamin C (stabilizes antioxidant activity)
- Niacinamide (complementary barrier support)
- Hyaluronic Acid (carrier for water-soluble phenolic compounds)
Conflicts
- Strongly alkaline environments (pH > 12)
- Cationic surfactants
