La Roche-Posay Anthelios UVMune 400 Invisible Fluid SPF 50+ is designed for those who want daily sun protection with a high level of defence and a lightweight feel on the skin. It suits sensitive skin and has a minimalist formula tested for gentleness.
The formula is designed to provide protection against both UVA and UVB radiation, as well as infrared radiation. It contains Mexoryl 400, which protects against very long UVA rays, and Netlock technology which helps the protection spread evenly and adhere well to the skin.
The product is also water-, sweat- and sand-resistant, making it suitable for daily use and more active days. It is light, non-sticky and leaves no white marks.
The sun protection is specifically developed for sensitive skin and tested under dermatological control. The formula is also hypoallergenic and developed with a minimal ingredient set to reduce the risk of irritation.
SPF 50+ provides very high protection from the sun. The broad protection covers UVA, UVB and infrared radiation. La Roche-Posay highlights Mexoryl 400, which protects against ultra-long UVA rays.
Netlock technology gathers microdroplets into an even and stable film on the skin. This helps the sun protection feel light, not run and not migrate. The formula also includes La Roche-Posay Thermal Spring Water.
