Zinc oxide

Zinc oxide is like magic powder that you put on your skin to help protect it. It's made from a fancy metal called zinc and oxygen that you can't see because they're too tiny.

When you put zinc oxide on your skin, it acts like a shield by reflecting the sun's harmful rays away from your skin. This is very important because the sun's rays can hurt your skin and make it red, bumpy, or even burn it!

But don't worry, zinc oxide is here to help! It can be found in special creams, lotions, or even in some types of makeup to help keep your skin safe and healthy. Just ask a grown-up to help you put some on before you go outside to play or swim, and you'll be protected from the sun's rays all day long!
