Nah can’t give you specifics but it’s pretty easily researched. you need to keep your perfumes in a cool, dark place with no humidity. it’ll last longer. i have vintage dior fomulations that are very very old but still smell on point because how i handle them. i’m talking decades. but it can be a matter of years if you keep them in sunlight or in your bathroom. i know some hardcore fumeheads and some perfumers that have wine coolers and fridges to store theirs….i’m not at that level yet. i need all that space for gelato and alcohol slushies.
