This is a very good question.

Today, there are various Botulinum toxin type A injectables available, marketed under different brand names such as Dysport and Xeomin, but Allergan Botox is still considered the GOLD STANDARD.

FDA labeling states that Botox is not interchangeable with any other product like it on the market. While many brands have tried to replicate Botox's unique formula, Allergan is the only one that has been thoroughly researched, tested and studied for its efficacy.
