Curious about the various levels of perfume? Perfumes are complex combinations of natural materials and synthetic products in various concentrations. The most expensive and heavily scented product is extrait perfume or pure perfume or parfum which contains the most perfume concentrates (as much as 40 percent). Eau de parfum contains less "juice" generally as high as 15 percent perfume concentrates. This is the most popular concentration. Eau de toilette is far lighter with less than six percent perfume concentrates and does not last as long. The higher the concentration of scent the longer it lasts. A scent will change as it wears on your body and reveals its various layers. Fragrances include top notes, the "first impression" that the scent makes on your nose, heart notes that form the body of the scent and base notes which form the foundation of the scent. It is the heart and base notes that stay with you throughout the day.
