Where designer perfumery chases broad appeal, a house like Initio Parfums Prives pursues a specific vision — and Side Effect is a clear expression of that philosophy. An EDP built on Warm Spicy, Rum, Vanilla, Tobacco, Sweet, composed by Unknown, it offers something mainstream perfumery rarely delivers: genuine singularity at a price that can still be justified.
