Used primarily as a UV absorber in sunscreen and sun care formulations, where it effectively protects the skin from UVB radiation, helping to prevent sunburn and long-term UV damage. The potassium salt form enhances water solubility, making it suitable for incorporation into lotions, creams, and serums. It may also be included in some dermatological products for potential anti-inflammatory benefits, but caution is advised as it can cause allergic reactions or irritation in sensitive skin.
