The final stage of a perfume’s development on the skin, where the base or bottom notes become most prominent and enduring. This phase occurs after the initial top notes have evaporated and the heart notes have mellowed. In natural perfumery, dry down reveals the deep, rich scents derived from materials like resins, woods, and musks, which are known for their longevity and stability. These base notes provide the lasting impression of the fragrance, creating a signature scent that can linger for hours. The art of crafting a well-balanced dry down is crucial for natural perfumers, as it ensures the perfume evolves beautifully over time, maintaining its complexity and allure.
