Science
Mechanism of Action
This extract functions through several molecular pathways: it upregulates the AQP3 gene to enhance cellular water transport and stimulates ceramide synthases (CerS2, CerS4, CerS6) to fortify the lipid barrier. Its high antioxidant profile—including alpha-carotene and beta-cryptoxanthin—neutralizes reactive oxygen species (ROS) and suppresses MMP-1 expression, effectively mitigating UVB-induced collagen degradation and oxidative aging.

Dusting Analysis
As a popular botanical extract, it is frequently included at very low concentrations (below 0.1%) for marketing purposes ('label appeal') rather than for its enzymatic or barrier-repairing benefits, which typically require higher inclusion levels.
