Planning on taking one more sunny vacation this summer?
Be sure to check the expiration date on your sunscreen. They generally have a three year dating system, so they may not be effective beyond that expiration date. The chemical sunscreens (like PABA and avobenzone) are particularly unstable.
Slather on a good sunscreen, and enjoy the rays!
