Perfumes Structure & Behaviour - Most common complaint Why the fragrance Does Not last long enough on my skin.
Knowing that perfumes smell by evaporating, you can take better care in applying them. When applying, spread the perfume, but don't rub it in vigorously, because the heat you create will evaporate the top notes and weaken the overall smell.
Chemical reactions can also morph your perfume on the shelf. Visible light has enough energy to bust the bonds in fragrance molecules, and bright sun will singe your perfume in as little as a week. Air can also corrode your fragrance by oxidation -- the same process that turns uncorked wine into vinegar. Storing your perfume at room temperature, in the dark and in a spray bottle preserves it well. Then, it will have a shelf life of at least five years.
But what about your chemistry?
Many people complain, as to why the fragrance does not last on our skin, or that their is something wrong with the fragrance, as it is weak on their skin, and does not last long.
Your own body temperature and oiliness seem most important and play a big role in why the fragrance lasts differently on different people. The top notes will evaporate faster from warm and dry skin than cool and oily skin. Otherwise, by the time the heart notes emerge, the perfume smells the same on everyone.
You have learned about your perfume's structure and behavior. You have spread, but not rubbed vigorously.
