Perfume design is the art and science of creating fragrances that evoke emotions and memories. It involves blending various aromatic compounds, essential oils, and solvents to produce a unique scent. Perfume designers, often called perfumers, use their knowledge of chemistry and olfactory perception to craft fragrances that appeal to different preferences and occasions. The process typically begins with selecting top, middle, and base notes, which together create a harmonious scent profile. Top notes are the initial scents perceived, while middle notes form the heart of the fragrance, and base notes provide lasting depth. This careful layering results in a well-balanced perfume that can be enjoyed throughout the day.
