Botulinum toxin is a neurotoxin that temporarily paralyzes muscles by blocking nerve signals. Its primary healthspan relevance is indirect, stemming from the potential psychological benefits of a more youthful or relaxed appearance, which can positively influence mood and social perception. It also has approved medical uses for conditions like chronic migraines and muscle spasticity.
