What is non nano zinc oxide?

Non nano zinc oxide is a form of zinc oxide that has particles larger than 100 nanometers in size. This means that the particles are too large to be absorbed into the skin and are instead left on the surface, providing a physical barrier against harmful UV rays. Non nano zinc oxide is commonly used in mineral sunscreens due to its ability to provide broad spectrum protection against both UVA and UVB rays.

Non nano zinc oxide is considered to be reef-safe, as it does not pose a threat to coral reefs and marine life like some chemical sunscreens do. It is also suitable for sensitive skin, as it is less likely to cause irritation or allergic reactions compared to chemical sunscreens.

Overall, non nano zinc oxide is a safe and effective sun protection ingredient that provides long-lasting protection against the sun’s harmful rays.
