The ad copy shows a comparison of a woman's photo - one supposedly taken from Week 1, and the other on Week 6. Now, it doesn't really take a genius to figure this out, but it is so blatantly obvious that the "Week 1" photo and the "Week 6" photo are one and the same. The only difference is the Week 6 photo went through some digital image manipulation to remove the wrinkles and whiten her complexion. But everything from the angle of the photo, the lighting effect, the facial expression, etc. point clearly to the fact that its the same photo!
Now, I am not saying that the product does not do what it claims to do. Perhaps it can really perform miracles in 6 weeks. What I just find offensive with the whole campaign is the fact that they obviously used digital image manipulation to fool people. If they were really serious in their claim, why not take a real photo of that woman in Week 1, then again in Week 6 and let the audience decide. Using Photoshop is a cop-out.
