Consumer Reports recently tested 65 popular brands of sunscreen and found out something shocking! That SPF 30 you’ve been buying might actually only really work like SPF 8 if you’re in and out of the water a lot. 43% of the sunscreens they tested didn’t stand up to water and had significantly lower SPF values than they claimed on the bottle.

A full report from CBS News can be found here, but here are the best bets if you need to get out into the sun this weekend:

1. La Roche-Posay Anthellos 60 Melt-In Sunscreen Milk lotion
2. Pure Sun Defense SPF 50 lotion
3. Banana Boat SunComfort Continuous Spray SPF 50+
4. Aveeno Protect + Hydrate SPF 30
5. No-Ad Sport SPF 50 lotion
6. Equate Sport Continuous Spray SPF 50
