Science
Mechanism of Action
This ingredient functions as a biological shield by binding to specific membrane receptors on keratinocytes. Through competitive inhibition, it physically intercepts inflammatory signals to halt the cytokine cascade (IL-1α, TNF-α) and reduces the activity of Phospholipase A2. Simultaneously, it stimulates the synthesis of β-endorphins, which provides a neuro-soothing effect that alleviates sensations of stinging, itching, and general discomfort.
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical trials involving seborrheic dermatitis demonstrated a 59% reduction in erythema and an 81% decrease in scaling over a 28-day period.
- 02 In vitro studies confirm the inhibition of ICAM-1 cell adhesion and a significant reduction in Prostaglandin E2 (PGE2) release.
Transparency
Dusting Analysis
To achieve the neuro-soothing and redness-reduction benefits documented in clinical data, concentrations between 1% and 3% are required; inclusions below 0.5% are typically for label claims rather than therapeutic efficacy.
