Does sunblock expire?

[Coolamber]

Found some sunblock when I was cleaning. Not sure how old it is. Does anyone know if it expires. Looked on the bottle, no date found.

There's been a thread in "Around the House" on this subject in the past couple of days. You might check there.
HTH!

it is less effective after a year or two.

Definitely! It is suggested that it be replaced after every season. I used expired sunblock once when I was in high school (didn't know it was) and got a horrible sunburn. Please just throw it away. It's just not worth it.

Thanks, I was not sure where to post. I think I will just trash it. To bad looks like a new bottle that got pushed to the back and hidden.
