In perfumery, essence refers to the concentrated aromatic oils extracted from natural raw materials such as flowers, fruits, spices, woods, and resins. These essences are the fundamental building blocks used by perfumers to create fragrances. Each essence contributes its unique scent profile, ranging from floral and fruity to woody and spicy, ensuring diversity and complexity in perfume compositions. Extracted through various methods such as distillation, expression, and enfleurage, essences form the core ingredients that define the character and quality of natural perfumes.
