How to Store and Care for your Perfume
Always keep the cap on your perfume bottle closely tight. Oxygen is a big enemy to perfume and will spoil its chemical composition.
Keep your perfume away from heat and direct sunlight. Your perfume should be kept in a cool dark place if you want it to retain its quality for a long time. If you like to keep your perfume on a counter, use it within a year.
Apply your perfume with the stopper that comes with your perfume bottle and not with your fingers, so that you do not spoil your perfume with residues off your fingers.
Your perfume should last about 5 years if properly stored and cared. However, be aware that it could spoil earlier than that. If it changes color, darkens or clouds, it means that the perfume molecules are breaking down and that your perfume has spoiled.
