The difference between the sprays and perfume oils is mainly due to concentration of pure perfume in the fragrance, combined with the additional alcohol elements which may affect the overall performance of the perfume spray.
This difference in potency influences the longevity and projection of the scents. The intensity of performance when it comes to perfume oils is incomparable to its alcohol-mixed spray counterpart. On average our perfume oils last between 10-12 hours, with very good and intensified projection for at least 5 hours.
A good spray usually can last 6-8hours before needing a refresh, with an average projection time of around 2-4 hours. This does not mean the oils have a stronger scent as the smell received is dependent on the ingredients used to make the fragrances.
Whereas edts tend to be sprayed on clothing, perfume oils are usually used directly on skin pulse points. This allows the scents to intertwine with your body’s own chemistry individualising the scent to you. Nonetheless, both can be used wherever you desire.
Lastly perfume oils are much more versatile and can be mixed into some of your other skincare products, if you regard yourself as an apothecarist.
