Sinapic acid is widely used in the cosmetic and pharmaceutical industries due to its strong antioxidant properties. It helps protect the skin from oxidative stress and UV-induced damage, making it a valuable ingredient in anti-aging creams and sunscreens. Its anti-inflammatory and antimicrobial activities support its use in formulations targeting acne and skin irritation. In food preservation, sinapic acid acts as a natural stabilizer, preventing lipid oxidation and extending shelf life. It is also being studied for potential health benefits, including managing blood sugar levels and reducing the risk of chronic diseases like diabetes and cardiovascular disorders. Additionally, it serves as a building block in synthesizing other bioactive compounds and functional materials.
