How do Dysport and Bocouture compare in volume needed and effectiveness?

I suggest getting only FDA approved treatments if you are in the US and this includes Dysport, Botox or Xeomin. Best, Dr. Emer.

Bocouture is a Merz product that is a cosmetic UK brand of a botulinum toxin product marketed in the United States as Xeomin.  Xeomin is very similar in dose and clinical behavior to BOTOX made by Allergan.  While Xeomin is widely available to licensed physicians in the United States, it is generally not available to non physicians.  Bocouture is not FDA approved for the United States.  Generally the federal government prohibits the direct importation of prescription drugs included products like botulinum toxin.  You could face civil and criminal prosecution.  I strongly suggest you consult your personal attorney before doing this.

Bocouture is not approved for use in the U.S. so whomever is trying to sell it to you is committing a crime by importing and dispensing illegal products. "This
