Some perfumes can last a decade, while others can last less than a year. The average perfume will last three to five years. In general, perfumes with heavier base notes will last longer than those with lighter and more delicate fruity or citrus notes. The duration of the perfume depends on the chemical composition and on how the perfume is stored.
Many perfumes don't have a set expiration date and can last between 1 and 10 years.
