1. First off, don't put perfume on over any kind of scented lotion or oil. Perfume chemicals interact in all sorts of crazy ways, so something that smells great on your bare skin could be downright noisome paired with the wrong moisturiser.
2. Another thing many people don't realise is that rubbing your wrists together, which causes friction, can cause uneven development over the course of a day, poor wear, and the wrong proportions of different notes. Instead, spray or dab wrists separately, or touch them together gently.
3. And finally, don't use more than a single spritz if you're wearing eau de parfum that's in an atomiser. Body mists and eau de toilettes are more dilute and therefore better for all-over spritzing, but your typical perfume is designed to be used sparingly.
