Summary

Skin Conditioning Moisturizing Hydrating Skin Brightening Reduces Hyperpigmentation Antioxidant Anti-aging Anti-inflammatory Gentle Exfoliation

Science

Mechanism of Action

This extract functions primarily by enhancing skin hydration through its rich amino acid profile, including natural moisturizing factors (NMF) like Serine and Glycine, which strengthen the skin's moisture barrier. It visibly brightens skin by effectively inhibiting melanin overproduction and tyrosinase activity, thereby reducing hyperpigmentation. Furthermore, it provides significant antioxidant protection via compounds such as vitamin E, ferulic acid, and gamma-oryzanol, which neutralize free radicals and support collagen integrity, contributing to anti-aging benefits. Its anti-inflammatory properties offer soothing effects, and natural phytic acid provides a gentle exfoliating action.
