First there was Botox Cosmetic; then 2009 brought the Botox alternative Dysport. In 2010, expect to see a few more Botox rivals, including a topical form of the popular wrinkle relaxer and at least one more injectable. A couple of injectable Botox cousins are in development, but PurTox will likely be the next to get a nod from the Food and Drug Administration (FDA). The main difference in these injectables seems to be how long the results last and how quickly the products start to work on your crow’s feet.
