Perfume oil can last for many hours, but there is no exact number that will be the same for everyone.
Your skin, the fragrance itself, where you apply it, how much you use and how often that part of your body gets washed can all affect longevity.
That is why the neck is one of the areas Lily Essences recommends. Fragrance on the wrists may disappear faster simply because your hands are washed throughout the day.
With Lily Essences, one application is normally enough for the day, and some wearers may continue noticing the fragrance into the next day when it is applied to an area that has not been repeatedly washed.
Different oils can also perform differently on the same person.
For a little extra staying power, try applying a thin layer of petroleum jelly to the skin before the perfume oil.
