Essences are concentrated aromas that form the base of any fragrance. They are blends of natural extracts, essential oils, plants, fruits, flowers, herbs, and other synthetic compounds, produced in laboratories, which imitate or enhance certain natural scents. The choice of a perfume’s essences and their concentration determine the type of final fragrance: Perfume, Eau de Parfum, Eau de Toilette, Eau de Cologne.
