Women of a certain age in this town hardly need to be informed of the lip-plumping, wrinkle-eradicating properties of non-animal-sourced hyaluronic acid, rendering this viral campaign for Restylane (thanks, helpful publicists who believe our readers would be interested in their client's miracle product) all the more bizarre. Maybe their market research has revealed that middle-aged producers' wives who've recently been discarded in favor of twentysomething assistants frequently hunt for anonymous revenge-sex on the YouTubes and the MySpaces, where they might stumble upon the ad dramatizing the kind of liberating, youth-restoring cougar-maulings they'll enjoy once the initial swelling and bruising of their first round of injections subsides.
