The Original Roll-On Pheromone Perfume. In 1985, our master perfumer had the intuition to formulate alluring fragrances with human-compatible pheromones: “The Original,” Pure Instinct’s first pheromone fragrance, was born. The lightly fragranced oil absorbs quickly and leaves the skin soft to the touch, blending perfectly with your body’s chemistry. Make it your signature scent. Perfectly suitable not only for day-to-day use but also for an intriguing date night.
