Science

Mechanism of Action

Oryza Sativa Bran/Germ Extract offers comprehensive skin benefits through its diverse composition. It acts as a powerful antioxidant, combating free radical damage and mitigating premature aging, attributed to components like ferulic acid, vitamin E (tocopherols and tocotrienols), and gamma-oryzanol. It enhances skin hydration and reinforces the moisture barrier by providing essential fatty acids (linoleic acid, oleic acid), squalene, and other lipids, thereby preventing transepidermal water loss. The extract also contributes to skin brightening and reduction of hyperpigmentation through the gentle exfoliating action of natural phytic acid and the inhibition of melanin synthesis by gamma-oryzanol and phenolic acids. Additionally, its B vitamins and phytocompounds confer anti-inflammatory effects, effectively calming redness and soothing irritated skin while also supporting overall collagen integrity.
