Xeomin (incobotulinumtoxinA), made by Merz Pharmaceuticals, is a neurotoxin approved by the US FDA for the treatment of moderate to severe frown lines between the eyebrows. IncobotulinumtoxinA is made from the bacteria that causes botulism. Botulinum toxin blocks nerve activity in the muscles, causing a temporary reduction in muscle activity.
Frown lines form when facial expressions are made as the muscle under the skin contracts. Over time, as your skin ages, these repeated expressions cause lasting frown lines. Neurotoxins, such as XEOMIN®, are prescription medications that block the release of chemicals that cause these muscle contractions so frown lines are softened.
Worldwide, more than 84,000 people have been treated with Xeomin injections. The U.S. is actually the 20th country to approve this new drug. It is available in 50-unit and 100-unit vials.
Better or worse then Botox?
The same ingredients in Botox are used in Xeomin, though Xeomin is somewhat of a purer form of the toxin. Xeomin has no additives, just botulinum toxin type A. This may mean that there is less risk of developing antibodies against Xeomin than other available neurotoxins. The body develops antibodies in response to a foreign invader and attacks. In theory, antibodies could prevent a neurotoxin from having its desired effects. The effects of Xeomin occur within one week, and the results last from three to six months, making it comparable to Botox in terms of both onset and duration of action.
