N-420 is a type of sunscreens used in the operation of windows and other glass products. It is a type of Neutrogena sunscreen that has been specially designed to protect against both UVA and UVB rays. It is made with a special blend of active ingredients including titanium dioxide, zinc oxide, and micro-encapsulated octisalate helps for an invisible and lightweight protection. This particular sunscreen offers a physical and chemical protective barrier, which means it not only physically blocks the sun's rays, but also chemically alters any harmful UV radiation that may penetrate through. It is not water-resistant, so it will need to be re-applied every two hours or after swimming or sweating.
