Perfume should be kept in a dry, cool place away from sunlight or heat. Sunshine is the first big enemy that perfume stores, it can decompose the spice material in perfume. Too hot or too cold can also upset the balance of essential oils in the perfume, which in turn can change the scent. Perfume without sprinkler head ,has to use itas soon as you open, otherwise it will evaporate slowly. If you have perfumes that have not been used for a long time, they can be stored in a tupperware out of the light, which can greatly prolong their life.
