BOTOX®, a registered trade mark of Allergan Inc., and Dysport® (Ipsen's product) are different forms of purified botulinum toxin A, and are produced by the bacterium Clostridium botulinum, the cause of a dangerous disease called botulism. Botulinum toxin is a neuromuscular blocking agent, which means it causes paralysis of the injected muscle by preventing the release of acetylcholine from motor nerve terminals. Without its nerve supply, the muscle fibre withers away. The muscle strengthens again as the nerves regenerate.

Botulinum toxin reduces sweating by blocking the sympathetic nerve fibres that control sweat glands.
