This sunscreen is terrible. It claims that it's sweatproof, but it is not and I bought it for my hubby who sweats very easily... My hubby used it when we went to the beach and I sprayed his back for him, and he sweat (as per usual). A few hours later when I went to reapply to him, he had this red streak down the middle of his back... Wherever he sweat, the sunscreen went off with it, and he had a burn in the shape of the sweat line. Everywhere else it was fine, except his back. They shouldn't consider this sweat-proof if it clearly cannot stand a man's sweat! For $20 for a sunscreen, I'd rather spend it on one that does what it's supposed to.
