Requirements of the health and quarantine authorities: All cosmetics (including perfumes) sold in the country need to clearly indicate the production and use period. Therefore, the shelf life of the perfume bottle is generally 3-5 years, and the perfume after opening is best used up within 24 months or 36 months, which is the recommended use period, not the requirement that it must be used up within this period.
But in fact, perfume is mainly composed of essence and ethanol, alcohol itself has the effect of disinfection and corrosion, so perfume actually has no fixed shelf life. If preserved well, the taste can still be very good after 10 years, which is the "antique aroma" that many people like to collect; If kept in a poor environment, even within the so-called shelf life, it will still deteriorate.
When saving the perfume, pay attention to placing the perfume at room temperature away from the light, and avoid shaking the perfume when usually used to prevent excessive volatilizing of the alcohol flavor, resulting in the fragrance of the perfume becoming lighter.
