Does sun block expire?

i found a bottle of sunblock and it doesnt have an expiration date on it, it just might be older than a year. It's a Coppertone brand with spf 45; does sun block lotion really expire?

Answer:
Certain sunblocks do expire, but some dont. The only risk your taking by wearing an expired sunblock is not getting proper sun protection! So to be safe I would just buy some new sunblock. Hope I helped.

yes

yes it does . If it wasn't bought this season toss it and buy a new bottle. You might find the sunblock won't do it's job and you will burn. better to be safe than sorry.
