Over the July 4th celebrations, you will most definitely be enjoying family and friends outside, and you should be wearing sunscreen while you’re out in the sun.

When you choose sunscreen for yourself and your family, it's important to know what the safest option is.

Conventional sunscreens contain four times as many hazardous chemicals and ingredients linking them to cancer and birth defects.
