I am having excellent luck with this sunblock! I have sensitive skin and am extremely sensitive to some aerosol and scented products. This has not been an issue with me in any way. We do apply this outside for more ventilation. I have not used this on small children. This has primarily been tried by adults in my household. It’s super easy to apply, not oily, and so far is providing sun protection. I have not used this and then entered water. Our use has been for just everyday running around. It has not irritated anyone’s skin and no one has been burned by the sun- so gonna say it’s a win. This is very likely my new brand. I will update this review over the summer with how it holds up at the beach and pool. It’s doing a great job for basic outside recreation and play

Nice refreshing sunscreen

Great spray sunscreen. Don't even notice any difference between this organic sunscreen and regular sunscreen. It sprays nice and evenly and provides good protection for a reasonable time. I've used this during a number of workouts out in the sun, sweating, for a few hours at a time. It sprays pretty lightly on, and stays on. Once it sprays on, while it feels light, you do feel it (like a little sticky on your skin), same as any other sunscreen really though.
