Hey Lubianka!
We can assure you that fragrance is 100% authentic and gave you an answer to every question you had about the fragrance and reassured you of your concerns. We even offered a full return.
The MOST likely reason, which we've seen time and time again this summer and last is that the fragrance chemistry is messed up (short-term) because of the heat the fragrances endure during the transit process during summer. We do inform customers to allow it to sit 3-5 days in a dark room temperature room to allow the fragrance to settle again. 9/10 this works for our customers.
As for the fragrance being outside of cellophane, that is standard for Creed purchased in massive bulk. Creed only come wrapped in cellophane if they're intended for a boutique and or retail store.
We do admit that the quality of the perfume may be temporarily degraded due to the temperature, but we do stand by our answer that the fragrance isn't inauthentic as we do purchase from authorized distributors.
