 I have summarized the first premise in the argument in a way that refers to the image because it is difficult to fully capture the (almost magical) transformation the advertisement promises if we try to translate it into words. The implicit premise in the standardization is a key part of the argument because it is a key assumption made in the move from the (visually) explicit premise to the conclusion. So understood the argument can be analyzed and evaluated as an argument which has a questionable explicit and implicit premise (and an inference which is an instance of the fallacy “Affirming the Consequent”).
