Botulinum toxin, or botulinum neurotoxin, is a highly potent neurotoxic protein produced by the bacterium Clostridium botulinum and related species. It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis.
Allergan Botox refers to a brand of botulinum toxin type A, commonly known as Botox, which is produced by Allergan, a global pharmaceutical company. Botox is widely known for its use in both cosmetic and medical applications. It works by temporarily paralyzing muscles to reduce the appearance of wrinkles and fine lines, providing a smoother, more youthful appearance.
