The Egytians was the fist people ever to make perfume. They used-smelling oils on their bodies before getting dressed. Some perfume recipes, that date from about 5.000 years ago, still exist. Most of the perfumes at that time are made from flowers and only the very richest people could afford buying them.

Today, perfumes are usually created with a perfume company. As well as ingerdients from over 500 plants, other ingredients are making by chemists in a laboratory. One of the most famous place that produces perfume is the town of Grasse in France. Its climate makes it perfectly for growing flowers - around 4.000 kilos of rose, for example can be used to make just a small number of perfume. After a perfume is made, much time and money is spent on desiging a bottle and box and advertises it
