Botox is an FDA-approved neuromodulator and cosmetic injectable made from botulinum toxin type A, a highly purified protein derived from the bacterium Clostridium botulinum. When administered in small, controlled doses, Botox works by temporarily blocking nerve signals to targeted muscles, allowing them to relax. This reduction in muscle activity helps smooth dynamic wrinkles in the face and neck, softens the appearance of fine lines, and can help prevent new lines from forming over time.​
