Widely used in sunscreen formulations as a chemical UVA filter for its ability to absorb UVA light (310-360 nm) effectively. Protects skin from harmful UVA rays, preventing premature aging, wrinkles, and other photoaging damage. Photostable, meaning it maintains efficacy under sunlight exposure. Often combined with UVB filters and other UV absorbers to provide broad-spectrum protection. Suitable for sensitive skin due to its water-soluble and gentle nature. Helps maintain skin health by reducing the risk of UV-induced damage, including indirect contributions to sunburn when part of a complete formulation. Commonly found in lotions, creams, and sprays for daily sun protection.
