In an ad for something like, say, shampoo, toothpaste, a toothbrush or face wash or somesuch, you'll see a little animated close-up of the effect said product is supposed to have on you. Like... glowy thingies smoothing your flaky hair or a nice blue barrier forming against that nasty plaque. The celebrity, non-celebrity or voice over person will witter on about the benefits that the product will have on your hair, teeth, pores, etc. Sometimes, fancy chemical names (often made-up or proprietary) and Techno Babble are thrown around. Compare with Shaving Is Science.
