There are several different types of Botulinum toxins (A, B, C, E, F).The Botulinum Toxin used for cosmetic purposes is the Type A Botulinum or BTX-A. Botulinum Toxin of type A is marketed under the names of Neurotoxin, Neurotoxin-Cosmetic (USA) and Vistabel (Europe) by Allergan Laboratories and under the name of Dysport by the Ipsen-Biotech Laboratory. Neurotoxin and Dysport are the specialities used in medical indications (ophthalmology, neurology, and otorhinolaryngology). Vistabel and Neurotoxin-Cosmetic are the specialties of the Allergan laboratory which obtained the marketing authorization (A.M.M and FDA approvals) for wrinkle correction but their action is exactly identical to that of Neurotoxin.
