Application and care
Can I leave perfume in the car
Do not use a parked car as routine perfume storage, especially where it can become hot or exposed to direct light. Carry only what you need and remove it with your belongings.
A HUME Fragrance buying guide

Separate carrying and storing
A necessary journey is different from leaving the bottle in a glove compartment for days.
Avoid deliberate heat
Warming perfume is not a recommended way to improve its scent or projection.
Ask about specific exposure
If a bottle was left in heat and now seems different, contact the maker with the facts rather than trying to repair it yourself.
Try this before you buy
Remove any bottle routinely kept in the car and choose a more stable storage location.
