Botox is a drug made from a neurotoxin produced by Clostridium botulinum bacteria. It works by temporarily paralyzing muscles when injected in small doses by preventing nerve signals from reaching muscles. While mainly used cosmetically to reduce wrinkles, botox also has medical uses for treating conditions like migraines, excessive sweating, and muscle spasms by paralyzing the overactive muscles. The botox procedure involves diluting and injecting the toxin directly into muscles, with effects seen within 24-72 hours as it disrupts nerve signaling to muscles.
