Science
Mechanism of Action
This extract operates through a dual-action pathway: it inhibits pro-inflammatory signals like prostaglandins and cytokines (IL-6, TNF-α) via the MAPK and NF-κB pathways, while simultaneously boosting the production of essential barrier proteins such as filaggrin and loricrin. Its rich flavonoid content, specifically apigenin and luteolin, provides a robust antioxidant shield against environmental aggressors.

Clinical Evidence
High confidence2.5%
Key findings
- 01 Clinical data indicates that concentrations between 2-5% optimize skin barrier fortification and deep hydration.
- 02 Research into pharmaceutical applications shows a range of 1.5-2.5% is the 'sweet spot' for accelerating wound healing and reducing acute inflammation.
- 03 Safety assessments confirm efficacy for soothing benefits in leave-on cosmetic applications at 0.5%.
Transparency
Dusting Analysis
While often included in marketing for its 'calming' reputation, many commercial formulas use it at negligible levels (below 0.1%). To move beyond a label claim and achieve physiological barrier support, concentrations should ideally meet or exceed 0.5%.

Formulation
Stability
Displays maximum stability in acidic environments (pH 3.0–5.0); active flavonoids degrade significantly in alkaline conditions above pH 8.0. Formula integrity is compromised if processed above 70°C.
