Science

Mechanism of Action

This oil delivers its beneficial effects through a concentrated profile of fatty acids (including oleic, linoleic, palmitic, and stearic acids), vitamins (E, B, D, A), and a comprehensive array of antioxidants such as gamma-oryzanol, ferulic acid, coenzyme Q10, beta-carotene, lycopene, and squalane. These components actively protect the skin from free radical damage and oxidative stress, thereby combating premature signs of aging. It improves skin elasticity, minimizes the appearance of wrinkles, and helps reduce dark spots and hyperpigmentation by inhibiting tyrosinase activity. Furthermore, it supports skin barrier repair, acts as an occlusive agent to boost hydration, soothes irritation, and stimulates microcirculation for natural regeneration and a youthful glow.
