Lost Chemistry Ephemeral Dyadic: A Fragrance of Love and Passion Introduction Lost Chemistry by Ephemeral Dyadic is a fragrance that captures the essence of crazy, passionate love—the kind of love that breaks hearts, starts wars, and ruins lives. It is the love that etches itself into your soul, that you feel every time your heart beats, that burns in your memory and returns every time you are alone and the world fades away. This love that still hurts, that makes you sit and stare at the floor, wondering what the hell happened and why.
