Alpha Dream Technologies pheromone formulas contain a unique silicone carrier that promotes a timed, linear release of pheromones. When their formulas are sprayed on to the skin, the effect is most pronounced for the first 4-6 hours, depending on the ambient temperature. The silicone base is more advanced than most pheromone products available, as it bonds to the skin and forms a water-resistant layer that delivers the pheromones over a longer period of time.
