Cinnzeylanol is primarily used in cosmetic and skincare formulations for its antioxidant and skin-conditioning properties. It helps protect the skin from oxidative stress caused by environmental factors such as UV radiation and pollution. Due to its ability to support skin barrier function, it is commonly found in anti-aging creams, serums, and moisturizers. It may also contribute to improving skin elasticity and reducing the appearance of fine lines. Additionally, Cinnzeylanol is utilized in some natural and plant-based beauty products owing to its origin from botanical sources, offering a stable and mild active ingredient suitable for sensitive skin types.
