The advertisement by Proactive, clear skin acne treatment, using jessica simpson as one of their customers is an example of a Post Hoc fallacy. This is due to the fact that the commercial asserts the idea that anyone who uses their product has the potential to have a life just like Jessica Simpson. Most people are aware of the fame attached to Jessica's name, therefore the company uses this to their advantage. The use of a major public figure to insinuate that people who use their product could become 'famous' is not logically correct. In reality, there is no correlation between using Proactive skin care and becoming famous.
