Science
Mechanism of Action
This extract operates through several key pathways. Its antioxidant capacity stems from compounds like vitamin E derivatives, such as garcinoic acid, which also aid in reducing pyrimidine dimers and supporting DNA repair. Flavanones contribute to maintaining skin elasticity by inhibiting elastase. Additionally, unsaturated fatty acids, including linoleic acid, are believed to reinforce the skin barrier and promote wound healing. The extract also demonstrates anti-irritant, soothing, and broad-spectrum antibacterial and antifungal activities.
