How to Store Perfume
Keep your perfume away from sources of direct light and heat. Strong lighting, both natural and artificial, will cause for your perfume to lose it’s potency and colour. Heat is also a factor that can decay the quality of your perfume.
Bottles that have spray caps are preferable to those which do not. Bottles that use the cap as a means of application to the skin allow for bacteria from the skin to enter the perfume bottle itself and therefore contaminate the perfume.
