Science
Mechanism of Action
It functions via a triple-action pathway: first, by inhibiting pro-inflammatory cytokines such as IFN-gamma and IL-17 to reduce redness; second, by blocking lipoxygenase enzymes to prevent oxidative damage; and third, by upregulating the filaggrin pathway to boost the synthesis of Natural Moisturizing Factors like Pyrrolidone Carboxylic Acid (PCA).

Key findings
- 01 A 3.0% concentration demonstrated a 29.9% increase in skin PCA levels within 24 hours, significantly improving barrier hydration.
- 02 Clinical trials at 1.0% to 2.0% showed a measurable reduction in erythema and sensitivity by modulating inflammatory signaling molecules.
- 03 In vitro testing confirmed potent anti-inflammatory activity (IC50 7.01 µg/ml) through enzymatic inhibition.

Dusting Analysis
Because it is an expensive botanical extract, it is often included at sub-clinical levels (<1.0%) for marketing purposes. To achieve the physiological barrier repair and anti-redness benefits seen in clinical data, concentrations between 1% and 3% are required.
The Formula
Formulation
Stability
The extract is sensitive to photodegradation and high alkalinity; stability is best maintained in slightly acidic environments below pH 7.0. High flavonoid content may lead to darkening if exposed to strong oxidizers.
