The differences among these are the amount of essential oils in the fragrance. The most potent type of fragrance that you can buy is the straight perfume. Next would be Eau de Parfum, then Eau de Toilette, and finally Eau de Cologne. The higher the percentage of essential oils the longer your fragrance will last, and the less you need to apply.
- Perfume (Parfum): It is the strongest fragrance available, consists of a 15-30% concentration of perfume essence. This means that not only do you need to use less, but also that the fragrance lasts longer, typically for up to 6 hours, depending on skin type.
- Eau De Parfum (EDP): It is lighter than Perfume, with an 8-15% concentration, but still has long lasting characteristics, from 3 to 5 hours. It is less expensive than pure perfume.
- Eau De Toilette (EDT): It is lighter than EDP, with a 4-8% concentration of the essence. It usually lasts for 2 to 4 hours.
- Eau De Cologne (EDC): It is lighter than EDT, often referred to just as Cologne and has the greatest dilution of fragrances with a 3-5% concentration of perfume essence. It usually lasts for 2 hours.
- Tester: Testers are an excellent way to purchase a perfume or a cologne at a discount rate, without compromising on the quality. Testers are made by the manufacturer to help promote their fragrances. They usually come in a plain box and may have “Tester” somewhere on the bottle. They are not used. Testers contain the original quantity mentioned on the bottle.
