La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF50 is a high-performance, dermatologically tested sunscreen engineered to provide superior protection against harmful UVA and UVB radiation. Featuring the exclusive Mexoryl 400 filter, this formula is specifically developed to shield the skin from ultra-long UVA rays, which penetrate deeply to contribute to long-term skin damage and premature aging.

Key Features and Benefits:
* Advanced UV Protection: Expertly formulated to defend against ultra-long UVA rays (380-400nm) while maintaining high-level SPF50+ protection against UVB radiation.
* Invisible Finish: The ultra-lightweight, fluid texture absorbs rapidly into the skin without leaving a white cast, greasy residue, or sticky film, making it an ideal base for daily use under makeup.
* Water and Sweat Resistant: Engineered to withstand significant moisture and perspiration, ensuring consistent and reliable protection throughout the day.
* Skin-Friendly Formulation: Rigorously tested on sensitive skin and eyes, this fragrance-free, paraben-free, and non-comedogenic formula is designed to prevent pore blockage.
* Comfortable Wear: This minimalist, hypoallergenic formula offers high tolerance and is suitable for all skin types, including individuals prone to sun-related skin sensitivities.

Usage Instructions:
Apply the product generously to the face and neck area 15–20 minutes prior to sun exposure. To maintain optimal protection, reapply frequently and liberally, particularly after swimming, sweating, or towel-drying. Shake well before each use.
