A Spritz That Makes Your Perfume Last Twice as LongI have a theory that some people are stickier than others. (Stay with me.) On some, things like lipstick and perfume last all day; on others, they need to be reapplied frequently. If you’re a fragrance lover who happens to fall into the latter camp,Fragrancelock, $34, is for you. It’s an essential oil-based spray you spritz over your favorite perfume, and it makes the scent last twice as long. I have no idea how this sorcery works (something about creating a mesh on your skin), but it does. I sprayed my favorite perfume on both arms and added a spritz of Fragrance lock on only one side — at the end of the day, you can guess which arm still smelled delicious (while the other smelled like arm).
