Percocet used for pain relief is a narcotic medication and prescriptions can prevent people from getting high on Percocet without medical reason.In fact, the Percocet high feeling can get you into lots of problems.
I think the formula of the perfume itself decides how fast it will spoil. My perfumes from Britney Spears Curious and Salvatore Ferragamo went bad within a year and a half. The Britney Spears one developed some precipitation and started smelling like alcohol, while the Salvatore Ferragamo just smelled plain weird.
Remove the scent of perfume from your skin by rubbing a cotton ball or pad soaked in witch hazel, rubbing alcohol, hand sanitizer or even unflavored vodka over the area where you applied it. A paste made of equal parts baking soda and water can also be used to get rid of perfume odor on your skin.
