I don't think there is one that lasts for 24 hours, but the fact is some sunscreens last for a short space of time, so the Sun Protection Factor is good but limited in duration, and you may need to apply it 2-3 times a day.

There might be some kind of consumer organisation or website, that does indpendant testing, that might be able to give you specific statistics for many well known brands, but I don't really know what else to say.

I know sunscreen last 2 or 3 multiply the spf. so if it's 50 multiply by 2 or 3, that's how long it could stay...:)

I heard the protection doesn't go up after SPF 15, so you just hafta keep applying. Good luck!

You should reapply sunscreen about 3 times a day, if you are staying outside all day, that is. About every 2-3 hours is a good idea.

And always wear something over SPF 30 or more. If you have a habit of staying outside more than 3-4 hours, it's wise to go up to SPF 50 or more for even better protection.
