Science

Mechanism of Action

Rich in polyphenols (proanthocyanidins, resveratrol), linoleic acid (Omega-6), oleic acid (Omega-9), and vitamin E, it provides strong antioxidant protection and reduces transepidermal water loss. Its high linoleic acid content supports skin barrier integrity, regulates sebum, and offers soothing anti-inflammatory effects.
