With proper care and storage, perfume can last for years and retain its original scent. I was gifted the bottle of Chanel perfume by a family friend who said she didn't like the scent. When I spritzed it, it smelled rancid. The perfume had gone bad. How does perfume go bad though? And more importantly, how can you make your perfume last throughout the day?
Store in fridge
Toilet waters (Eau De Toilette/diluted perfume) and Cologne can be kept in the fridge because they have a higher alcohol level and contain less essential oils. Do not store actual Perfume or Eau De Parfum because extreme temperatures at any end can alter the scent by destroying the top notes. Direct sunlight and temperature changes, such as storing in a bathroom, is the quickest way to ruin your perfume.
Spray on pulse points
So most people don't know that heat activates the scent molecules in perfume. If you spray your perfume on your pulse points the flow of your blood will warm these areas and really bring the scents out.
Moisturize or apply Vaseline where you plan to spray your perfume. This will create a barrier that will prevent your body from absorbing the oils/scents, and keeps it on the surface. It also helps it stick and help the scent last longer.
Use a perfume oil as it is more concentrated, or layer the oil formula under the perfume on top to really give it a lasting kick.
Don't rub your wrists together or rub anything after spraying your perfume. By rubbing it, it immediately starts breaking down molecules and diminishing the scent.
