Yes. Heat and humidity can break down your perfume and cologne faster, causing the scent to change or fade more quickly when you wear it. Ideally, store your fragrance in cool, dry place. You should also pick darker areas as light also affects the integrity of the fragrance.
If you have unopened bottles, keep them stored safely in a drawer or cabinet until you're ready to use them. This extends their shelf life, which can be over a decade when unopened.
