Botox (made by Allergan) has had a strong hold on the facial aging and line production market on the face. This has allowed it to charge any price it wanted. Now, however, there are 2 new competitors being released in the United States this year. With the release of any new product, it is usually better to wait a period of time prior to being the first. These products are VERY SIMILAR to Botox and have been tested extensively so this bodes very well for its safety. The good news is now we can expect Botox prices to drop in the next year or so.
Dysport aka Reloxin (made by Medicis). Early use of it by injectors has shown that it diffuses more or spreads out more than Botox which may mean it may not be as ideal for facial applications.
