Roll-on perfume oils, generally, are much more concentrated, as you apply them directly onto the pulse points, rather than spritzing them into the air. “It’s much more reactive to the heat of your natural body temperature,” says Johnston. Plus, these are typically formulated with more fragrance itself: “At by/rosie jane, our eau de parfum is traditionally between 25 and 30% fragrance, but our oils are between 50 and 100% perfume,” she continues.
Perfume oils also typically contain carriers like jojoba or coconut oil, which hydrate the skin simultaneously–and hydrated skin, as we mentioned, can help a fragrance last. Finally, they’re easy to throw into your bag for touch-ups later on, if you notice the scent starting to drift off.
