What are the various types of Botulinum Toxin ?

There are several types of Botulinum toxins (A, B, C, E, F). The Botulinum Toxin used in dermatology is the Type A Botulinum or BTX-A. Botulinum Toxin of type A is marketed under the names of Botox®, Botox-Cosmetic (USA) and Vistabel® (Europe) by Allergan Laboratories and under the name of Dysport® by the Ipsen-Biotech Laboratory. Botox® and Dysport® are the specialities used in medical indications (ophthalmology, neurology, and otorhinolaryngology). Vistabel® and Botox-Cosmetic are the specialities 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 Botox
