Anthelios SX is a light, non-greasy, fragrance-free daily use moisturizer with sunscreen that combines Parsol 1789 (avobenzone) and an innovative ingredient, Mexoryl SX (ecamsule) to help provide UVA protection. It is allergy-tested, PABA-free, suitable for sensitive skin and offers 24-hour hydration. Anthelios SX has complete broad spectrum protection. Anthelios SX contains MEXORYL™ SX, the most effective FDA-approved organic filter designed to protect against short UVA rays (maximum absorption at 344nm) with high photostability, a key factor in sunscreen protection efficacy. This high photostability means the sunscreen will maintain a higher UVA protective ability longer and not degrade as quickly as other FDA approved UVA filters when exposed to the sun.
