I'm sure the sunscreen works, but I was not really able to use it effectively.First of all, it has very thin coverage so you really have to spray and spray to get enough out. Second, you have to rub it in after you spray, so you may as well just have a bottle of lotion. Third, the way the bottle and cap are designed, once your hands are even the slightest bit greasy or slippery (from rubbing in the lotion), it is impossible to hold on to and spray without it slipping out of your hand.I would not buy this again and it was a waste of money because I ended up buying another brand at the local drugstore on vacation and not even using this.
