Science

Mechanism of Action

Oryza Sativa Germ Cell Culture Extract operates through a rich composition of antioxidants, vitamins, minerals, lipids, and amino acids. It actively neutralizes free radicals, mitigating oxidative stress and the visible signs of premature aging. Its lipids, including linoleic acid, are integral for reinforcing the skin's protective barrier and maintaining optimal moisture levels. Key amino acids such as Serine and Glycine, which are natural moisturizing factors, enhance hydration, while B vitamins stimulate collagen production to support skin elasticity. Furthermore, the extract addresses hyperpigmentation by inhibiting tyrosinase, an enzyme crucial for melanin synthesis, leading to a brighter, more uniform complexion. Its anti-inflammatory properties also contribute to soothing irritated skin.
