Alcohol, that’s why they evaporate quickly.
Perfumes are just smelly water with lots of alcohol and some perfume oils. Body mists contain the most alcohol and least oil, EDP and extraits the least alcohol and most oils.
Perfumes may cause allergic reactions but rashes go away after a while. I’m not sure why you’re getting acne from a body mist which has little oil. It’s a body mist right, not an EDP? Whichever it is, there must be something clogging your skin; thus, the acne. Or the high alcohol content might be drying out you skin so the skin is responding by producing more oils and in turn, acne.
I’d try to spray on clothes instead of skin.
So sorry you’re experiencing that, collecting fragrances is a great hobby to have. ☺️
