when does sunblock expire?

Question:

Answers:
whenever the date on the bottle is!

Other Answers:
on that little date thats printed on the bottle

The expiration date should be on the bottle.

read the bottle if no dates are listed and it does not smell gross it's probably just fine.

it depends on the strength of it, i think. SPF 15--15 minutes; SPF 45--45 minutes and so forth

It depends on what the bottle says. Its usually around 3-4 hours if you apply a copious amount. Just a bit of advice: Buy the one's that are water resistant if your going to be around water and always remember to Slip Slop Slap!

SPF 15-30 last for 30 mins to an 2 hours so we need to re-apply them afterwards. While sunblock with SPF 30 and above could last for 4-8 hours. Thats what I know from my dermatologist 's advice. But they are right, reading labels and instructions from the bottle will help.
