Widely used in sunscreens and skincare products for its strong UV absorption, especially in the UVB range. It helps protect the skin from sun damage by filtering harmful ultraviolet radiation. Due to its water solubility and photostability, it is often combined with other UV filters to enhance broad-spectrum protection. Commonly found in lotions, facial creams, and cosmetic formulations where long-term stability and safety under sunlight exposure are important. Also used in some hair care products to prevent UV-induced color fading and damage.
