This is a great sunblock and helps with my oily skin. My face gets oily throughout the day a lot that I had to wash my face every 2 to 4 hours. This cut that down to every 8 hours. I haven't tested the water proofing of it, so I'm not sure how it holds up. But, if it's able to absorb all the oil that my face makes (as disgusting as that sounds) then I believe the waterproof works great. There's also not greasy like texture like a lot of sunblock out there, so I highly recommend it for your face.
