The world of perfumery has three arch-nemeses in life: heat, light, and humidity. This triple threat works cooperatively to degrade the molecules in your perfume, reducing the purity of the perfume and introducing off-notes, causing catastrophic damage to the scent profile.
The biggest dilemma perfume lovers may face is the need to showcase their beautiful perfume bottles. I am also one of them. For your regular perfumes that you use frequently, you could place them on table tops that are not directly affected by light, away from a direct heat source. Nonetheless, as long as you aren’t placing your perfumes on the countertops of your shower rooms, your perfume should live a happy life of ~2 years.
To protect your most valuable perfumes, it’s recommended to seal the bottles and place them in a dark and dry location to hide them from danger. Perfumes that are stored this way can theoretically become immortal to degradation.
