PHYTIC ACID

Last update on Jun 29, 2026

Phytic Acid, also known as inositol hexaphosphate. It is a naturally occurring antioxidant and chelating agent found in many plant seeds. In cosmetics, it is valued for its ability to bind metal ions, stabilize formulations, and provide mild exfoliating and brightening benefits. It is commonly used in serums, toners, masks, and anti-aging products. It improves stability, enhances brightening effects, and supports skin clarity while being relatively gentle compared to traditional acids.
