Economics of perfume
More money does not necessarily mean better perfumes. Some of the most popular fragrances of the past were relatively cheap formulae. It is possible to mix expensive raw materials and end up with a pricey mess.
Usually, the oil concentration that a fragrance contains affects its price. This is why EDP will typically cost higher than EDT variant of a perfume. Ingredients also considerably impact the price of perfumes. Perfumes using natural exotic rare ingredients for oils (for example, the house of Creed) will tend to be priced higher than those using synthetic oils.
Unfortunately sometimes, what you end up paying for is the marketing cost and the image associated with a brand and not necessarily the cost of raw materials comprising the scent.
When deciding to purchase a new fragrance – let your nose decide!
Lifespan of a perfume
The shelf life of an average bottle of perfume is 5-8 years from the date of manufacture.
It is next to impossible to specify the accurate number of application from a bottle of perfume. A 100ml single bottle typically lasts for around 3 months assuming 8 sprays per day.
Extend the life of your perfume by storing it in cool, dark and dry environments – such as your bedroom. Rapid heat fluctuations (like found in a bathroom) will cause the molecules in a fragrance to break apart. Sunlight does the same thing as well. Ensure the bottle cap is secure, to prevent the fragrance from evaporating.
