Eucerin Sun Fluid Anti-Age SPF 50 is a very high factor daily facial sunscreen for all skin types. It helps to prevent premature skin ageing caused by sunlight (known as photoaging) and protects skin from sunburn and sun-induced damage. While most modern sun care products protect against UVA and UVB rays, Eucerin Sun Fluid Anti-Age SPF 50 takes sun protection to the next level by also working to combat the oxidative stress caused by High Energy Visible Light (HEV Light). The formula moisturizes as it protects, boosting skin's own ability to retain moisture, plumping skin from the inside out and reducing the appearance of deep wrinkles.
