The latest wrinkle-filler Juvederm, which is set to be launched officially into market by January 2007 and has patients lingering for it. Before its official launch into market, Juvederm dermal filler has been injected on many people, free of cost to test the efficacy of the injection. Doctors selected by Juvederm's parent company Allergan, have been conducting these tests to test to know, how Juvederm compares with Restylane. Experts say that Allergan should conduct a scientific trial where participants don't know which product they receive and doctors evaluate results. The company is trying to create a buzz, through the trial release. Experts are disappointed at Allergan's drive to create a buzz as a part of marketing strategy. They feel that it is not scientific or legitimate.
