La Roche-Posay Anthelios UVMune 400 Invisible SPF50+ Sunscreen offers SPF50+ protection with exclusive MEXORYL400 filter technology, helping to defend against UVA, UVB and Ultra Long UVA rays. The formula is water, sweat, and sand resistant for long-lasting, ultra-high protection. Designed with comfort in mind, the cream hydrates skin without feeling greasy. MEXORYL400 is a breakthrough revolution in UV protection in 30 years; new exclusive UV filter protects against even the most insidious UV rays: ultra-long UVA (380-400nm). Netlock Technology is another breakthrough ingredient in suncare. The polymers lock the oil within micro-crystals, making the formula non-greasy. These crystals group to form a strong network of protection providing homogenous, non-migrating and very resistant protection. Addition of glycerin helps to hydrate and moisturise the skin after initial application. Gentle, anti-eye-stinging, fragrance free formula, the La Roche-Posay Anthelios UVMune 400 Invisible Sunscreen showcases the best of the brand's skincare technology, tested for efficacy and mildness.
