Hi there! Tank you fo reaching out to us about you recent Alien Fragrance purchase. We are sad to hear that you feel that the scent has changed. While it is possible that minor changes have been made in the formula of a product; however, the performance should meet or exceed previous results and may not be noticeable at all. There are different reasons why a formula might be changed; availability of ingredients, changing industry requirements, and product improvements are common examples. The ingredients listed on the physical product are always the accurate listing. However, if your perception of the perfume has changed slightly, this may be due to several factors, such as the method of application (the olfactory effect of perfume is different depending on whether it is sprayed or applied onto the skin), the ambient temperature, or even becoming accustomed to it. We hope this information has been helpful and we appreciate you taking the time to reach out.
