How to store and keep them so that they can last long for best use
Yes, perfumes do expire. The shelf life of a perfume can vary depending on the ingredients and storage conditions, but most perfumes last around 3-5 years. After this time, the scent may change or weaken, and the perfume may not perform as well as when it was first purchased.
Not sure if “expire” is the term, but depending on their concentration, the scent definitely changes due to reactions over longer periods of time
