Don't waste your money on this jellyfish sting protective lotion. After reading of the instruction, I and my wife carefully applied a good amount of the lotion to cover every inch of skin that can be exposed before getting into water. We checked each other and made sure to cover ever inch of exposed skin. Guess what? We still got stung by jellyfish, not once, not twice but a lot.
