Botox injections are most known for their ability to minimize the look of wrinkles on the face. They're also used to treat problems like cervical dystonia (neck spasms), hyperhidrosis (excessive sweating), an overactive bladder, and lazy eye. Botox injections may potentially be beneficial in the prevention of chronic migraines.

Botox injections temporarily stop a muscle from moving by injecting a toxin called onobotulinumtoxinA. The bacteria that causes botulism, a kind of food poisoning, produces this toxin.
