Botulinum toxin is known as one of the most poisonous biological substance. It is a neurotoxin produced by the bacterium Clostridium botulinum. There are seven distinct forms of botulinum toxin, types A?G. Four of these (types A, B, E, and rarely F) cause human botulism. Botulinum toxin A and B are used for therapeutic and aesthetic procedures. The increasing cases of spasticity, cervical dystonia and chronic migraine, surge in demand for facial aesthetic, and rising number of product launches and approvals by key players are likely to drive the growth of the global botulinum toxin market during the forecast period.
