I just bought the Eye Envy starter pack and I have some questions. First of all, are you supposed to refrigerate both the solution and the powder or just the solution? Secondly, the EE website says that the solution only lasts 2-3 weeks if left unrefrigerated. At the store where I bought the EE, it was not being refrigerated. The solution has a very unpleasant smell to it. Is that smell normal or should I question whether or not the solution has gone bad?
